| Abstract |
Methods for control of pesticide contaminated wastewater were studied. Evaluation of practices that are currently used to handle pesticide contaminated wastewaters was followed by development of a system that could be used to collect the pesticide contaminated wastewaters. Then a treatment plant was developed to remove pesticide from contaminated wastewaters and produce a high-quality effluent. Three physical-chemical treatment options were evaluated. A flocculation/coagulation/sedimentation step was evaluated using alum as the coagulant. Additional studies were done using filtration and coalescence. Flocculation/coagulation/sedimentation removed a high percentage of the pesticides. The filtration and coalescence steps were less effective. The supernatant from the first step was then passed through activated carbon columns. A hydraulic loading rate of .5L/s-sq m was determined to be adequate with a residence time of approximately 15 minutes. The concentration of the pesticides in the clear effluent was usually less than 1 mg/liter. |
