Ion-exchange pretreatment of water after resin regeneration with reverse osmosis reject brine
Ion-exchange (IX) softening as a practical pretreatment method for membrane desalting of water was conducted at the Bureau Testing Desalinization Test Station, Longmont, Colo. from July 1976 to October 1976. Water was imported from LaVerkin Springs, Utah for use at the test station. The concept demonstrated, was one of reducing calcium in raw LVS (LaVerkin Springs) water below sulfate fouling concentration by IX, desalting by RO (reverse osmosis), and using the recovered reject brine for regeneration of the exhausted IX resin. The test results demonstrated IX pretreatment of LVS water can be operated as a closed-loop exhaustion-regeneration cycle. Only the reject brine from RO need be used to regenerate the IX resin. A process development test program is recommended at the LVS site to determine optimum process conditions, cost, and design criteria for IX pretreatment. (Peters)
