Analysis of Moringa Oliefera Seed Powder Reaction in Treatment Wastewater Comparing with Aluminum Sulphate and PAC Reaction

Due to the fact that in arid and semiarid areas, access to high quality water resources my have limitation, using purified wastewater for irrigation plays an important role. Although wastewater are so little comparing with needed irrigation water but using this much water can cause that we use higher quality waters for better consumption. This research has been alone in laboratory and there has been utilized the jar test set.
In this research has been attempted to analyze, the effects of moringa seed powders (Oliefera species) in comparison with Alum and Poly Aluminum Chloride (PAC) in wastewater treatment. For performing the experiments, we utilized urban wastewaters with mediun density. Efficiency of each coagulant was assessed by measuring a number of parameters including the hardness (total, Calcium and Magnesium), turbidity, electrical conductivity (EC), acidity, Coliform (fecal and total) before and after the treatment. It is noticeable that all methods of measuring the qualitative parameters were based on those described in the book of Standard Method.
This research showed that in optimum concentration Alum, PAC and Oliefera were able to decrease turbidity up to 99.5, 99 and 97.7 percent, respectively. The efficiency of eliminating total, Calcium and Magnesium hardness, fecal and total Coliforms in the best condition were 40 (100 mg Oliefera), 72.5 (100 mg Oliefera), 67(80 mg Oliefera), 99.8 (combination of 100 mg Oliefera and 15 mg Alum) and 99.7 (combination of 100 mg Oliefera and 15 mg Alum) percent, respectively.
Discussion and The results showed that the efficiency would be higher if Oliefera be combination with Alum or PAC. The Moringa seed powders decreasing sedimentation time, comparing with the Alum and PAC. So much, so that the sedimentation time was decreased from 30 min to 10 min. we have to remark that the bulk produced sludge in Moringa seed powder has less density comparing with the Alum or PAC. It also was easier to drain.
