A laboratory investigation of electrodialysis shows that ED is technically feasible of treating brackish water RO concentrate and may prove to be a viable treatment option for minimizing brine production....

Reverse osmosis (RO) membrane desalination may be employed as a technically feasible treatment process for brackish water (BW) sources, but the product recovery ratio for inland BWRO applications is typically from 75-90%. The economic and environmental costs of concentrate disposal significantly limit the development of inland RO applications. Thus...

Concentration of supersaturated brackish reverse osmosis (BRO) concentrate with electro dialysis (ED) research study by the University of Texas, El Paso. Simulated system recoveries were improved from 75-80% to 88-94% adding ED to the treat the concentrate....

Reverse osmosis (RO) desalination may be used for desalination of brackish and saline waters, but the product water may have low concentrations of hardness and alkalinity, which may corrode infrastructure. Addition of pH, hardness, and alkalinity may be required to meet potable water guidelines. Upflow calcite contactors may be used instead of li...

Researchers at UTEP partnered with El Paso Water (EPW) to develop the high-recovery concentrate enhanced-recovery reverse osmosis (CERRO) process. Implementation of full-scale CERRO units at well sites in El Paso have resulted in 70-75% recovery of RO concentrate with a specific energy consumption of 1.23 kWh/m? (4.6 kWh/kgal) and total estimated ...
