| Abstract | This study was carried out in order to determine the wastewater flows and characteristics of the pesticide formulation plant, and to investigate the feasibility of treating pesticide wastewater by activated carbon.
The quantity of wastewater from the pesticide formulation plant was about 5 m3 per month. The wastewater was characterized by a very high concentration of COD, and containing various kinds of pesticides. Endrin and DDT of the chlorinated pesticide group were found to be the major components in the waste
water. Concentrations of Endrin and DDT were found to be as high as 570 mg/land 60 mg/l, respectively. pH of the wastewater was maintained at about 8-10 by addition of caustic soda. Powdered activated carbon at a dose of 2.0 mg/l can remove 90% of Endrin from the original concentration of about 20 mg/l within 1 h; while granular
activated carbon at a dose of 25 g/l gave the same removal efficiency. It was found that pH of the wastewater had only minimal effect on adsorption. |
