The report gives results of laboratory and pilot studies of the treatability of pesticide manufacturing wastewaters, in an investigation of the suitability of individual pesticide manufacturing wastewaters for discharge to biological treatment systems, whether on site or publicly owned. Aqueous effluents from the manufacture of dinoseb and atrazine were evaluated in a hierarchical approach: the least costly treatments were evaluated first. Preliminary activated carbon filtration (to remove pesticides) followed by biological treatment (to reduce oxygen demand due to other organics) was found effective. Other treatments found inadequate were dilution with municipal wastewater and biological treatment and chemical pretreatment to hydrolyze the pesticide followed by biological treatment. Activated carbon filtration alone greatly reduced the phytotoxicity of the pesticide wastewater even though substantial breakthrough of some organic compounds occurred.
