Evaluation of Efficacy Wheat Stalks in Reducing Ammonia Solution (NH3)

Biological nitrification, in the system that has a proper substrate to replace bacteria is more efficient than other systems. The major problem substrates, such as substrates that are made of synthetic polymers are their high cost of production and environmental problems. The aim of this study using wheat stalks as a substrate cost as well as review performance on the survival of fish.

To do this, the study added 10% and 5% of the word water storage tank size (240 liters size) of wheat stalks (starch). Control over two groups, one control (no wheat stem) control group (three treatments with three replications). You can calculate this student 10, best, most, 24, 48, 72 and 96 hours after adding ammonia. A weight of 0.28 g is added to each tank in the test volunteer. Treatments at this stage observe pre-budget law, leading to limited reservoirs of wheat stalks containing mosques. Mortality rates were counted 24, 48, 72 and 96 hours after the addition of ammonia. There was no food. One-way ANOVA was used to compare data between treatments and each one by time. The means were compared by SPSS software using LSD test at 0.05 level of confidence.

The results showed that the ammonia treatment is significantly different than the control group (p > 0/05). The amount of ammonia in treated compared with each other, there was a significant difference (p > 0/05). Greatest amount of ammonia reduced to 10% of the wheat stalk; Lowest fish mortality rates in the second stage of the treatment, 10% of wheat stem (2 number), as well as the control group (without wheat) had the highest mortality of fish (15 number). Results of our study showed that nitrification cycle in the reservoirs that 10% of the volume is dedicated to wheat straw up to 32 times more efficient than the other tanks (tanks without wheat). Well as present study showed that the use the wheat stalks can have a significant role in the increasing the chance of survival of fish, in the face of hyper-acute ammonia.
