Bisphenol A is known as one of the emerging micropollutants with harmful effects on human health. This pollutant enters the environment through the discharge of municipal wastewater treatment plants. In this research, the salting out dispersive liquid-liquid microextraction method was investigated for pre-concentration of bisphenol A in drinking water and urban sewage effluent samples. Due to the high enrichment factor, this method enables the measurement of small amounts of bisphenol A in the examined samples.

In this method, bisphenol A forms a colored hydrophobic derivative of antipyrine with 4-aminoantipyrine in the presence of potassium hexacyanoferrate. In order to extract the resulting derivative, 250 µl of 2-phenoxyethanol was dissolved in 10 ml of the sample. Then, by adding 0.7 g of sodium chloride to the sample, fine droplets of extracting solvent were formed in the sample and the solution became cloudy. After centrifugation, the extraction phase containing bisphenol A derivative settled at the bottom of the test tube, and then, 20 µl of methanol was added in order to reduce its viscosity. The measurement was performed by a high-performance liquid chromatography at a wavelength of 480 nm. To optimize the process, the effect of the amount of 4-aminoantipyrine, potassium hexacyanoferrate, and buffer was investigated. Then, the figures of merit of the method were obtained and the performance of the method was evaluated on drinking water and urban sewage effluent samples.

Under optimal conditions (2-phenoxyethanol: 250 µl, 4-aminoantipyrine 1%: 100 µl, potassium hexacyanoferrate 10%: 80 µl, buffer pH 10: 10 µl, and sodium chloride: 0.7 g per 10 ml of sample), the enrichment factor of 106, the detection limit of 0.1 ng ml-1, the limit of quantification of 0.3 ng ml-1, and the relative standard deviation (RSD) of 3.2% were obtained. Meanwhile, the correlation coefficient (CC) of the calibration curve was equal to 0.9985. Moreover, the results of the analysis of water and urban sewage effluent samples showed that the developed method had suitable performance for the measurement of bisphenol A in real matrix samples.

Considering the low detection limit, high enrichment factor, and proper performance in real samples, this method can be introduced as a sensitive and efficient method for the measurement of very low amounts of bisphenol A in water and wastewater samples.

The remediation of heavy metal manganese from industrial wastewaters has always been a challenging issue for environmental experts. It has been found that different species of microalgae, including Spirulina platensis, can be used in industrial wastewater treatment to remove heavy metals. The main goal of this research is to reduce or remove the heavy metal manganese from the industrial wastewaters of factories by microalgae Spirulina platensis.

In this research, 8 types of industrial wastewaters were collected from different factories and after the algae reached the logarithmic phase, they were mixed with industrial wastewaters. Then, the concentration of manganese metal, the amount of metal absorption and the percentage of microalgae cleaning efficiency were determined by atomic absorption measurement. Also, cutting enzymes were designed for nucleotide sequencing of α-phycocyanin subunit gene from Spirulina microalgae. Then Clonewin software was used to confirm the primers and the target fragment was placed in the expression vector.

The results of atomic absorption evaluation showed that after exposure of spirulina to industrial wastewater for one hour, a significant decrease in the volume of the heavy metal manganese occurred. Also, the result of the α-phycocyanin subunit gene sequence showed 100% homology with the α-phycocyanin subunit gene sequence in the gene bank.

Therefore, Spirulina platensis has the ability to absorb manganese metal in industrial wastewaters from factories, and different expression vectors can be used for homogenization and expression of alpha subunit genes.

Heavy metals are one of the most common environmental pollutants that can enter coastal areas from natural and human sources and affect marine organisms and the human population. Heavy metals are a serious threat to human health, living organisms and natural ecosystems due to their toxicity, persistence and bioaccumulation characteristics. Many heavy metal ions are toxic or carcinogenic to humans. Heavy metals can lead to the destruction of marine ecosystems by reducing the diversity and number of species and through accumulation in living organisms and food chains. Heavy metals enter coastal and marine environments through various sources, including industries, and domestic sewage. Heavy metals from ship traffic effluents are among polluting sources. This study investigated the effect of this pollution on macrobenthic communities. The findings show that heavy metals have an effect on premature spawning, increase in mortality and decrease in the body's defense system in fish, decrease in growth and survival and irregular cell division in sea urchins, increase in mortality, delay in growth and prevention shell development and irregular cell division in crustaceans, and increased mortality, reducing body defenses, delaying growth, losing breeding capacity and reducing eggshell thickness in seabirds, and irregular structure and acute toxic condition and delay in growth in benthos. Urban and industrial activities are the main sources of marine environment pollution. As a result, it can be stated that environmental quality assessment in this sector can provide useful information for pollution control in coastal areas. Recently, the implementation of environmental legal frameworks in the European Community has increased the awareness of the importance of heavy metals in shipping effluents in order to achieve "good environmental status".

Hexavalent chromium is reported to be highly toxic, mutagenic and carcinogenic; hence treatment of water and wastewater contaminated with this element by low-cost and environmentally friendly methods is of great importance. Therefore the aim of present study was to evaluate the efficiency of Fe(II) modified bentonite for hexavalent chromium removal from a simulated wastewater.

In this study, Fe(II) modified bentonite was synthesized. Structure and morphology of bentonite were investigated by XRD and SEM techniques. Experiments were carried out as central composite design with three input parameters namely initial hexavalent chromium, pH and adsorbent dosage at 5 levels. Finally, the results were assessed by adsorption isotherm models.

The findings revealed that complete removal efficiency of Cr (VI) achieved at pH of 2, initial hexavalent chromium concentration of 20 mg/L and adsorbent dose of 5 g/L. The adsorption isotherm model found to fit well with Langmuir isotherm model and revealed that the monolayer adsorption of hexavalent chromium at adsorbent surface was happened. The equilibrium data better fitted the Langmuir isotherm model suggested a monolayer adsorption nature of the modified bentonite.

  The findings in this study showed the promise of use of Fe(II) modified bentonite for Cr (VI) removal. Moreover, response surface methodology can be used as an effective method to optimize hexavalent chromium removal from wastewaters.

The synthetic dyes pollution has turned out to be one of the most important environmental problems. Approximately 10000 different dyes and pigments are used industrially and over 0.7 million tons of synthetic dyes are produced annually, worldwide. Synthetic dyes are extensively in the textile dyeing, leather tanning, paper, food and medicine industries. The majority of these dyes are either toxic to flora and fauna or mutagenic and carcinogenic. The disposal of these wastes into receiving waters cause damage to the environment. Therefore, removing them from environment is imperative various methods for physical and chemical decolorization of dyes in wastewater but these methods are rather costly and sometimes product hazardous by-products. In recent years, biodegradation approach of its cost-effectiveness and safe method. In this method, microorganisms, particularly bacteria are used for removing dyes. The goal of microbial treatment is to decolorize and detoxify the dye-contaminated effluents.

In this study, bacillus albus bacteria were isolated Mazandaran industrial wastewater used as an example of gram-positive bacteria. Decolorization by these bacteria was investigated by a system which contained both medium and dye. The effects of operational parameters of indigo carmine including time, initial dye concentration, temperature, pH, shaking/non shaking, aerobic/anaerobic were tested. Ethics code: IR.UMZ.REC.1397.106

The results demonstrated that over a period of 54 h, at 50° C, 100 mg/l of concentration and pH=10, maximum decolorization of 95 percent was performed.

The present study confirms high effectiveness of bacillus strains in dye removal. The main experiment was focused on decolorization of indigo carmine in aeration conditions.

The entry of antibiotic residues into water resources along with domestic sewage, pharmaceutical, hospital, veterinary, agricultural products and fish ponds is important due to their sustainability and non-degradability. More than 80 types of pharmaceutical compounds and their metabolites have been found in water resources. Annually, about (100 to 200) thousand tons of antibiotics, which are about 15% of all drugs, are consumed in the world. Concentration of antibiotics in wastewater in the range of 3 /. Up to 200 micrograms per liter and above. Advanced oxidation (AOPs), catalytic, photoelectrocatalyst, ozone, hydrogen peroxide, photon reactions, and photofenton and membrane reactions have been used.

A total of 108 effluent samples were taken at pH 4, 7, and 9 at 10, 30, and 50 minutes at 15, 30, and 50 volts after the electrocoagulation process. Determination of cefazolin by HPLC Knauer device with C18 column equipped with UV with movable strontium phase and HPLC Grade water of Merck company with 30 to 70 ratio, set at pH equal to 8 with triethylamine, flow 0.5. Ml per minute and wavelength 270 nm, TS with 2540 B, pH with Eutech5500 device, COD with, 5220 D Alk with 2320A methods.

The removal efficiency of Alk, TS, COD and CFZ is 69.49%, 67%, 86% and 79.42%, respectively.

Electrocoagulation was used to reduce the pollution load of wastewater containing antibiotic compounds and resistant and emerging organic pollutants before discharging wastewater into the environment in order to purify the pollutant into an environmentally friendly process.

Chemotherapy with platinum-base cytotoxic drugs (PBCDs) are commonly used in treatment of different types of cancers. Significant amounts of these drugs enter the hospital effluent via urinary exertion of patients and could adversely affect the environment and different ecosystems.

The samples (n=7) of 24 hours' hospital effluent were collected from a central cancer hospital in Isfahan, Iran using an autosampler for one week. After preparation of the samples, platinum levels were determined by inductive coupled plasma spectrophotometry (ICP-OES). Data on annual PBCDs consumption were obtained from the hospital pharmacy. Data analysis was done applying ANOVA.

Annual consumption of PBCDs was 366.47 gr. Maximum and minimum concentrations of platinum in hospital effluent were 857 and 102 ng/L, respectively (mean concentration: 482.5±257 ng/L). Mean effluent platinum levels were found to be significantly correlated with daily administration of PBCDs (P<0.01).

Daily platinum release of the hospital’s effluent was about 1gr. The incidence of cancer has been increasing in recent years and many private clinics also offer chemotherapy treatments which could exacerbate polluting the environment. So, further studies are needed to evaluate the environmental effects of platinum from hospital effluents.

Petroleum products such as crude oil, gasoline and gasoline are the most commonly used in the world, the major pollutants of water. About 10 million tons of oil are burnt annually in the world. Therefore, the development of new technologies for the elimination and purification of oil pollution is essential. There are several methods for cleaning up oil pollution and its derivatives. In this research, straw and chalk absorber was used as an organic adsorbent to remove diesel oil from wastewater.

The straw and chalk were firstly determined using the FT-IR analysis. Then the adsorption experiments were performed discontinuously using diesel oil laboratory solutions. Optimum adsorption conditions were obtained by changing the factors affecting adsorption including pH, initial concentration of contaminant, contact time and adsorbent amount on adsorption at different levels, The oil absorption was determined by weighting method. Ultimately, the use of adsorbent for laboratory wastewater was studied.

The highest absorbent efficiency at the time of equilibrium was observed for absorbing oil using straw and chalk absorber in 15 minutes, which did not have a significant difference with other contact times (49.85% absorbance, P<0.05) and the lowest value was observed without a significant difference in 3 minutes (37.19% absorption). The effect of straw absorbent values in 2 g/L was significantly higher than other amount of adsorbents (51.48% absorption, P<0.05) and the lowest percentage of adsorption was significantly different from other values in 0.25 And 0.5 grams per liter (38.30%, P<0.05). The fitting of Isotherm showed that the adsorption of diesel oil by straw and chalk with both Freundwich and Langmuir models were consistent with the high R2 (R2 = 0.99 and R2 = 0.96).

Nutrient-rich effluents (mainly nitrogen and phosphorus) may lead to algae blooms and many harmful effects in aquatic environments. Micro-algae have been more effective among the various methods used for the removing of nutrients from wastewater. Microalgae Chlorella vulgaris has specific characteristics such as rapid growth, resistant to systems manipulation, simple and inexpensive production technology, as well as the rapid uptake of nutrients such as phosphate and nitrate. In the present study, two concentrations of chlorella vulgaris microalgae (13 and 26 million cells/mL) were injected into dairy effluent, diluted using distilled water by 25, 50 and 75%, and the amount of nutrient removal and microalgae growth were examined during the growth period. Results indicated that different concentrations of algae at various percentages of dilution (25, 50, 75%) had a significant effect on the removal of nutrients and algal growth (p<0.05). The absorption of nutrients (nitrate, phosphate and ammonia) were 57.01, 51.84 and 43.15 percent respectively that containing lower density of initial algae compared to the treatments of 2nd group (29.15, 51.84 and 43.15 percent) with higher algae concentration. In both algal concentrations, the highest percentage of phosphate and ammonia adsorption were in dilution of 25% effluent and the highest percentage of nitrate adsorption were in the first group with 50% dilution and in the second group with 75% dilution. The more percentage of nutrients (nitrate, phosphate, ammonia) was eliminated compared to the second group (26 million cells / mL) when the microalgae concentration (group I) was 13 million cells / mL. Absorption of nutrients was decreased by increasing the concentration of microalgae. Regarding to the percentage of nitrate adsorption, the higher absorbance in the dilution was occurred at the highest concentration of algae.

Azo dyes are the most commonly used colors in textile industry. These colors are among the pollutant materials in the environment. Moreover, they are discharged into the environment in combination with industrial wastewater and pollute the ecosystem. The purpose of this study was to isolate and detect bacteria biodegrading Methyl Red and Rubin Dyprsy colors from dye waste water. The soil samples and wastewaters from textile dyeing workshops, were utilized in this study. The samples were cultivated on a nutrient agar (N.A) medium containing the desired colors, and some of them were isolated from bacterial colonies after checking. After purification, 100 μl of bacterial stocks and colors at a concentration of 200 ppm were inoculated into the medium containing nutrient broth (N.B) with pH=7. Subsequently, the samples were incubated at 30° C for 6-7 days. The samples were separated and optical density of samples was measured using spectrophotometer after centrifugation in appropriate wavelength for each color (450 nm for Rubin Dyprsy and 490 nm for Methyl Red). Moreover, Gram staining and biochemical tests were carried out to identify strains. According to the results, 8 Gram-positive cocci and coccobacilli strains showed the most capability to degrade evaluated colors. The highest rates of decolorization by O3 and Y4 were observed for Rubin Dyprsy (46.80%) and Methyl Red (80%), respectively. The results showed that indigenous strains can be used for biodegradation of industrial dyes under applicable conditions.

The main objective of this study was to evaluate the surface and deep distribution of Pb, Ni and Cu in the wastewater-irrigated area of south of Tehran using GIS and Hydrus. It was expected to find a comprehensive information of heavy metals distribution and their accumulation in the soil. This study was carried out in wastewater-irrigated area of south of Tehran. Soil sampling from the top surface layer (0-15 cm) and wastewater channels was done. After sample analysis, ordinary Kriging method using different variogram in GIS was applied to explore the surface distribution of Ni, Pb and Cu heavy metals. Moreover, the deep percolation of heavy metals in the soil profile was simulated by Hydrus-1D in a duration of 210 days and the heavy metals concentrations in the soil were estimated. Exploration of the distribution of Pb using spherical model showed that the variation of this element was in the range of 20-70 mg/kg. This amount varied to 50-60 mg/kg for Cu and about 30 mg/kg for Ni. Moreover, the simulation of heavy metals deep percolation using Hydrus revealed that the most accumulation of heavy metals happened in the 0-15 cm soil surface layer and for deeper layer, this trend was descending. Comparing the concentration of Pb, Cu and Ni with the maximum allowable amounts of WHO standards demonstrated that Pb concentration was more than the threshold limit. Finally, the applied models could simulate soil’s heavy metals content for both surface and deep distribution in the studied area.

Environmental management system attempts to create and pursue requirements for the organizations to prevent catastrophic damages causing to their surroundings. One of the most important environmental aspects of thermal power plants is the impact on water resources. Moreover to high level consumption, the produced wastewaters will added to other pollutants.
The produced wastewater from the combined cycle power plant was monitored during one year. To compare pollutants from industrial wastewater with environmental standards, Kolmogorov–Smirnov’s test was employed. The main aspects of wasting and contaminating consumed water resources of power plant has been studied by using Preliminary Hazard Analysis and William fine techniques. Also the effective actions were performed to decrease and monitor the determined aspects.

Among the effective risks on water resources, 77 risks with low priority, 60 risks with medium priority and 12 risks with high priority has been identified. The chemistry refinery’s section and steam’s unit had the most identified risks. Among the risk controlling strategies, reducing risk’s intensity with 73 percent is the most effective strategy. Also, 14 percent of strategies refer to exclusion, 10 percent to transfer and three percent to acceptance of risk
Combining risk assessment methods and environmental pollutants concentration measurements could increased the accuracy and validity of the results by systemizing the identification process.

Background and Karaj River is the biggest aquatic ecosystem in Alborz province which is exposed to a variety of pharmaceutical pollutants. These pollutants have adverse effects of on surface water, biota and even humans. This research aimed to evaluate the level of contamination caused by widely used antibiotics in Karaj River, effluent, and wastewater treatment plants in 20 stations.
Sample preparation and filtration was done and concentrations of pharmaceutical pollutants were measured using HPLC (mobile phase). Data analysis was performed in SPSS V21.
The mean concentrations of antibiotics in Karaj River were as follow: amoxicillin 2.305, erythromycin, 2.229, gentamicin 2.231, and cephalexin 2.325 µg/l. In treatments plants higher concentrations of these antibiotics were found: amoxicillin 7.240, erythromycin 7.301, gentamicin, 7.390, and cephalexin 6.779 µg/l. In wastewater treatment plants the mean concentrations of amoxicillin, erythromycin, gentamicin, and cephalexin were 5.289, 5.362, 5.344, and 4.608 µg/l, respectively.
According to the significant positive correlation between the concentration of such pollutants in water samples, sewage and wastewater, the main reasons for entering these pollutants are believed to be the pharmaceutical residue discharges in urine and sanitary sewer network, septic tanks and sewage discharge of untreated aquaculture facilities in Karaj River. Inefficient treatment processes in controlling and reducing antibiotics are the main causes of high concentration of these pollutants in the environment that needs urgent control.

The aim of the study was to evaluate effluent quality of Ekbatan wastewater treatment plant for agricultural irrigation with CWQI model.
This study was a descriptive- analytical one and lasted for 48 months. In order to determine suitability of effluent quality for being reused in the agricultural irrigation, a total of 22 physicochemical parameters and 3 microbial parameters were measured during four seasons based on one weekly sample (a total of 54 samples). The results were entered into CWQI Calculator software to evaluate the effluent quality for agricultural irrigation.
CWQI value for agricultural irrigation is 56, it means water quality is frequently threatened (conditions often depart from natural or desirable levels). The results also showed that CWQI values for other usage such as drinking, aquaculture and livestock feeding are 30, 38 and 53, respectively and the best possible usage is for livestock feeding.
The results showed that the effluent quality was appropriate for irrigation but was in boundary region. Turbidity and Mercury are the most important factors of low CWQI value. According to the study, the effluent can be used for agricultural irrigation and high quality drinking water usage will be avoided.

Background and Environmental pollution by heavy metals and their transfer to soil and crops are a growing global problem. This study aimed to measure the concentrations of heavy metals in wastewater and sludge wastewater treatment plant in Gorgan, Iran.
In this cross-sectional study, 176 samples of effluent, and returned and dried sludges were analyzed in wastewater treatment plant in Gorgan, during six months in 2016. The concentration of Pb, Cd, Ni, and Cr were determined using polarography (Metrohm797 AV) and furnace atomic adsorption spectroscopy (AA 240 Varian Co.) in the laboratory of Health Faculty in Golestan University of Medical Sciences.
The average concentrations of Pb, Cd, Ni, and Cr in the effluent were 0.105 ± 0.06, 0.0089 ± 0.008, 0.095 ± 0.108, and 0.102 ± 0.175 mg /L, respectively. The concentrations of Pb, Cd, Ni, and Cr in returned sludge were 323.48 ± 217.65, 2.44 ± 3.3, 354.14 ± 322.79, and 388.53 ± 252.59 mg /kg of dry weight, respectively. Also, in dried sludge, the average concentrations of lead, cadmium, nickel, and chromium were 58.48±2.67, N.D, 30.31±1.98, and 506.25±813.81 mg/kg of dry weight, respectively.
The concentrations of heavy metals in wastewater effluent and dried sludge, except in returned sludge, were below the standards. Due to long-term use of effluents, necessity of treatment of other parameters, and the effect of bioaccumulation of metals in sludge, caution should be taken for their agricultural application. Also, because of importance of this type of contaminants in soil and food products, continuous monitoring by water companies is highly necessary.

Background and Many conventional disinfection methods of effluents raise some health, efficiency and economic concerns. In order to increase the efficiency of disinfection of real effluent, in this study, the catalytic ozonation process was performed and economically compared with chlorination.
Magnetic activated carbon was used as acatalyst in a semi-continuous reactor for disinfection of effluent of municipal wastewater treatment plant in Bandargaz, Iran in 2015. The efficiency of disinfection was determined by thermo-tolerant coliform as indication, and the effect of parameters such as catalyst concentration (0, 0.5, 1, 2, and 5 g/L), initial number of coliforms, contact time (1, 2, 5, 10, 20 and 40 min) and catalyst reuse on disinfection process was evaluated. Finally economic comparison was done with the chlorination.
The results showed that the efficiency of disinfection was increased by increase in the concentration of carbon nano-composite and contact time; at 1 g/L concentration of Catalyst about 1.99 log reduction was observed after 2 min exposure time in which the effluent standards were obtained; while 1.91 log reduction of micro-organisms was measured for single ozonation. The first-order kinetics constant of single ozonation (0.42 min-1) showed an approximately 9-fold increase when the catalyst (2 g/L) was added to the solution. After 7 times reuse of nano-composite, the diminution of efficiency was negligible (1.5%); and more than 57% fall of the cost was observed in a 5-year operational period compared with chlorination.
The catalytic ozonation with the new catalyst of effluent could effectively disinfect the effluent in a short-contact-time, and due to economic considerations it can be used as an effective and economical method in wastewater treatment plants.

The results were analyzed by analysis of covariance (ANCOVA) using SPSS 16.
Findings: The mean of TSS, COD, turbidity and fecal coliform in the horizontal roughing filter effluent had the significant difference within various hydroulic loading rates (P The HRF can be used as appropriate option, due to high efficiency and easy operation, to improve the quality of effluent from the polishing pond following aerated lagoons in order to provide national standards.

Rapid growing of Triton X-100 application in industries results in its appearance in effluents and threaten the aqueous ecosystems. Triton X-100 is not biodegradable and can accumulate in food chain. In this study, sorption capacity of six synthesized zeolites with different regular porous structure was studied for triton X-100 (TX-100) surfactant and the results were compared with Clinoptilolite natural zeolite of Damavand region. Within all zeolite studied, Beta(200) showed the highest sorption capacity (about 575 mg/g), which is due to its regular pore structure with large pore diameter, channel intersections, high SiO2/Al2O3 ratio and high surface area. Langmuir monolayer isotherm and pseudo-second-order kinetic equation could provide well-fitted to the experimental data in simulating adsorption behavior of TX-100 over Beta(200) zeolite. The adsorption feature was internal sorption and the intraparticle diffusion might be a rate-limiting control for Beta(200) zeolite. Results of experiments demonstrated that the hydrophobic zeolites with large pore diameter such as Beta(200) could be effective sorbents for industrial wastewater treatment features.
