UF pretreatment for SWRO: pilot studies

摘要: In recent years, the water filtration industry has seen an increase in planning and design of reverse osmosis plants for treatment seawater potable use. past, conventional chemical physical based pretreatment was utilized to reduce fouling RO membranes. last decade, hollow fiber ultrafiltration (UF) membranes have been introduced into municipal market surface ground under influence water. UF proven be cost effective practical these applications. Due need better pretreatment, use is now being considered as a viable solution (SWRO) plants. Although few commercial installations exist, extensive piloting SWRO underway. This paper will discuss two pilot studies which were recently completed. Each study purpose RO. Both pilots operated on Pacific Ocean however, one deep basal well whereas second with open intake. Ultrafiltration can provide product consistently low turbidity SDI (silt density index) levels, regardless quality. systems require significantly less space often power consumption than systems. As result, membrane are needs, especially locations limited or variable
