Abstract

Fabric filtration is a new trend in waste water reuse applications. In an attempt to improve the waste water quality resulting from a compact unit composed of an up-flow anaerobic reactor to obtain waste water effluent quality which is complying with the law 48/1982 for discharge in agricultural drains, and which can be used safely for unrestricted irrigation, this research study aims at testing the performance of four different fabric materials at the bench scale level at different operating conditions in order to identify the optimum operating conditions for the selected material. In this research, nonwoven fabrics and woven fabrics were tested as separation media. The effect of different water heads (pressure) and flux rates were tested to evaluate the fabric material removal performance. Two parameters were used to evaluate the removal of suspended solids and organic material namely; TSS and COD. Based on the results of this research study, nonwoven fabrics were found to be promising as separation media for the waste water and more effective than woven fabrics. Low flux rates and low water heads showed better results compared to high flux rates and pressure. The selected fabric material will be tested at the full scale real wastewater resulting from a village existing in a rural area in Egypt.
