Abstract

In this work, domestic wastewater taken from Alarein wastewater treatment plant Abha, Kingdom of Saudi Arabia, has been examined. Conductivity, pH, turbidity and TDS properties were measured for various samples. A 0.2Ám tangential flow hollow fiber microfiltration system was used for wastewater treatment and permeates were re-tested. Results obtained showed reduction of various wastewater properties. Turbidity was noticed to have higher reduction value from 10.2 NTU to 1 NTU for wastewater sample. It has been found that permeate flux increases by increasing the transmembrane pressure and crossflow velocity. The impact of fouling was also studied by looking at the reduction of permeate flux with time at various operating conditions. From the results it has been found that the use of microfiltration system has proven reliability in improving wastewater quality to be utilized for drinking purposes.
