Wastewater reuse has become more important over the years. Ultrafiltration (UF) is a key process in multiple applications of wastewater reuse including Reverse Osmosis (RO) pretreatment. The importance of UF is essentially the complete removal of solids. UF systems produce permeate with low Silt Density Index (SDI) and can reduce Total Organic Carbon (TOC) and phosphorous (P) with coagulant addition. This paper will discuss the pilot test results of UF treated wastewater effluent from a lagoon wastewater plant in New Hampshire. The pilot uses a new pressurized hollow fiber UF cartridge. The membrane cartridge is designed to produce high quality permeate at low fouling rates with difficult feed water. The membrane cartridge was able to handle high coagulant doses to produce excellent permeate quality. The coagulant dose was adjusted to both reduce permeate Total Organic Carbon (TOC) and control membrane pore plugging. An on-line UV254 monitor was used to control the coagulant rate in order to maintain permeate TOC levels as the feed water quality changed. The permeate could be used for direct reuse or as RO feed to reduce dissolved solids. Copyright © 2014 by the American Water Works Association. Source

Membranes are now an essential part of water recovery and recycling with industries striving to comply with increasingly stringent regulations to reduce or reuse wastewaters. It is rapidly replacing conventional methods to treat water. The articie gives an overview of the membrane systems and their applications in chemical industry. Source
