Comparison of Chemical and Biological Phosphorus Removal from Wastewater in Numaniya WWTP

Abstract

The water quality management for surface water aims to reducing the eutrophication by controlling and reducing the input phosphorus to the lakes and waterways. Two methods are currently being used around the world to remove phosphorus in wastewater: biological and chemical phosphorus removal. This study was conducted to predict and compare the efficiency of phosphorus removal between designed biological process for Numaniya WWTP and chemical process as well as EBPR plus chemical process. Results obtained from the study demonstrate that combination between the EBPR plus chemical process removal performs better than other choices in terms of effluent quality and alum cost .
