Abstract

Domestic wastewater pretreated in USAB (Upflow Anaerobic Sludge Blanket) reactors was subjected to different methods of posttreatment in an attempt to identify applicable schemes for developing countries. Among the parameters used for comparison were TSS, BOD, COD, nitrogen, coliform, and pH. The methods compared were sedimentation, anaerobic filtration, aerobic suspended growth and aerobic attached growth. It as found that the sedimentation and anaerobic methods were not as effective as aerobic methods. Aerated lagoons and rotating biological contactors were determined to be the methods of choice due to their efficiency of treatment, simple technology and acceptable costs.
