Abstract
Abstract In recent years, membrane-based ultrafiltration (UF) and reverse osmosis (RO) have become popular worldwide as possible alternative methods to conventional ion exchange and clarification processes for the production of potable water. The performance of UF and RO membranes was evaluated for treatment of surface and ground water from Prakasam District of Andhra Pradesh, India; namely, jagarlamudi well water (JWW), jagarlamudi pond water (JPW), veerannapalem old pond water (VOPW), and veerannapalem new pond water (VNPW). Pilot-scale UF and RO systems were built indigenously by incorporating commercial hollow fiber polyacrylonitrile UF and thin film composite polyamide RO modules, respectively. Operating parameters such as feed concentration, pressure, and cross-flow velocity were varied to study their effect on membrane performance. Effect of fouling on flux and rejection characteristics of the membrane was evaluated. RO membrane exhibited a rejection of 96.4% for JWW and VOPW feeds with reasonable ...
