Upgrading of the Existing Wastewater Treatment Plants in Egypt Using Discfilter

Abstract

Wastewater can be used after treatment. Using of the treated wastewater depends on the quality of the final effluent. The implementation of new wastewater treatment plants is very expensive; hence, upgrading of existing wastewater treatment plants can be considered as a suitable alternative. In this study, upgrading of wastewater treatment plant in Kom Hamada was evaluated by adding discfilter to improve the quality of the final effluent. TSS, BOD₅, COD, and helminth eggs were obtained for the influent and effluent over a period of four months. The average removal efficiencies of  TSS, BOD₅, and COD were found to be 79.98 %, 28.17 %, and 30.4 % respectively. The helminth eggs were totally removed. The effluent obtained after using discfilter was suitable for irrigation according to the Egyptian regulations for reuse of treated wastewater.
