Desalination Using Zeolite Membranes - Water Resources ...

Introduction• Produced water treatment– High salt concentration (as high as 20 wt%, 200,000 ppm)– Dissolvable hydrocarbon– High cost of treatment (∼$1.7/barrel)• Polymeric membrane– Serious hydrolysis at produced water condition– Sensitive to pH changes• Inorganic membrane– High flux ($$)– High thermal and chemical stability ($$)– Regeneration capability ($$)– Perhaps, low pretreatment cost ($$$$$$)
