Continuous Flow Seawater RO System for Recovery of Silica Saturated RO Concentrate
$0
Abstract
In a previous research study that was funded by the Texas Water Development Board (TWDB) and El Paso Water Utilities (EPWU), it was shown that a batch-treatment seawater reverse osmosis (SWRO) system can recover more than 85% of the water from the silica-saturated RO concentrate that is generated at the KBH desalting plant in El Paso, TX. Final feed water total dissolved solids (TDS) concentrations as high as 75,000 mg/L were routinely achieved. In this project, the pilot plant was converted from batch treatment to continuous flow. This project investigates how to recover most of the water from RO concentrates that are saturated with silica without fouling the RO membranes.
Originally funded as WERF project Desal-09-12.
