Zero Discharge Waste Brine Management for Desalination Plants

摘要

Desalination of brackish water at inland locations must consider environmentally appropriate and cost effective brine concentrate management and/or disposal. The Zero Discharge Waste Brine Management for Desalination Plants project examines a systems approach for desalination/brine management via a Salinity Gradient Solar Pond (SGSP) coupled with a Brine Concentrator and Recovery System (BCRS). The BCRS was tested over a broad range of operational conditions with the thermal energy derived from a SGSP. The relationship between system performance and operating conditions was analyzed to determine the economic and technical viability of the BCRS technology. Mathematical and computer models have been developed to describe the physical behavior of the BCRS and to predict its performance.
