Concentrate Enhanced Recovery Reverse Osmosis (CERRO)

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 cost of approximately $0.59/m? ($2.25/kgal). Cost-effective high-recovery desalination technologies, such as CERRO, are essential for drought-proof water supply in arid cities such as El Paso.
