Abstract
Laundry wastes are nuisant to individual purification if they rise anywhere the city sewage system is not. They have to be pretreated before their biological treatment because they contain high amounts of: surfacant, phosphate, etheric extract, suspension, COD and BOD. Purification of laundry wastes was performed by coagulation process with addition of flocculant. Among applied agents iron chloride was best. Optimum of coagulation condition was determined with 1000 mg/L FeC13, 0.2–0.3 mg/L of Magnafloc 336 as flocculant aid and pH in the range from 5.65 to 6.1. A high degree of reduction was obtained for all indices but residual concentration of anionic surfacants was still so high for purification by activated sludge method.
