The report gives results of laboratory and pilot studies on the biological treatability of wastewaters from the manufacture of ethylenebisdithiocarbamate (EBDC) fungicide. At concentration levels representative of EBDC production units and total plant wastewaters discharged to publicly owned treatment works (POTWs) (1 mg/L), results indicate little reduction in EBDC levels or in ethylene thiourea (ETU), an important decomposition product of EBDC as a result of biological treatment. Results of algal (Selenastrum capricornutum) and fish (Daphnia magna) bioassays on the treated wastewater indicated inhibition of algal growth and fish mobility, although little toxicity was indicated. Chemical oxygen demand (COD) removal by the biological (activated sludge) treatment unit was unaffected by the fungicide wastewater, although nitrification was reduced or absent in these units.
