Simple, cheap and low waste system for drinking water treatment using fabricated polymeric spiral wound ultrafiltration modules

Abstract

Simple, cheap and low waste system for drinking water treatment was designed and installed as a pilot system. Ultrafiltration polymeric membranes were prepared using polyvinylchloride and polyvinylidene di fluoride. The membranes were prepared by phase inversion process and were characterized by scan electron microscope, mechanical testing and membrane performance test. Spiral wound polymeric membranes modules were fabricated and used in fabricated pilot system. Continuous tap water stream was used in this experiment for six months. The results indicated that PVC spiral wound membrane module provides high productivity 9.36 m3/d, with organic removal (COD) 100%, blue green algae removal 100%, 95.7% for total algae removal and clear bacteria from water efficiently. The results of this study affirm that none of the water quality parameters (chemical or biological) that were monitored in this study exceeded the Standard Specification for Egyptian Drinking Water.
