Inland Desalination with Zero Liquid Discharge for Brackish Groundwater
Because of seawater intrusion and other human activities, groundwater quality is deteriorating in the gulf region. This has led to the use of inland desalination to produce good quality water. Clearly, any desalination process produces two streams; a clean water product stream and a reject concentrate stream (called brine) that must be disposed of. The opportunity to dispose the reject brine in the sea does not exist for inland desalination. Improper disposal of reject brine from inland plants results in major environmental problems. Achieving zero liquid discharge in such plants will avoid the problems of brine disposal and will conserve water resources by maximizing recovery. Available zero liquid discharge technologies are used mainly in industrial applications and they are prohibitively expensive for inland desalination. This project will focus in developing inexpensive and environmentally benign process for inland desalination with zero liquid discharge.
