Abstract
Post-treatment of effluent from an Upflow Anaerobic Sludge Blanket (UASB) reactor, that was fed with domestic sewage, was conducted in an integrated pond system to remove bacterial pathogen and further polishing of effluent quality. Rapid and efficient pathogen removal can be achieved in shallow stabilization ponds but their effluent biochemical oxygen demand and total suspended solids was relatively high, due to the presence of algae. Passing stabilization pond effluent through the duckweed ponds was expected to remove algae due to reduced light penetration. Duckweed ponds have revenue generating potential since the produced biomass can be used as animal fodder. However, when applied separately, their pathogen removal is poor.
