Chloride removal from wastewater
Chloride removal from wastewater
(OP)
Dear Experts:
I have been asked to find a way to remove chlorides from 2.1 million gallons of petroleum contact wastewater. Chlorides must be reduced from 850 mg/l to 500 mg/l (Cl-). This project is a one time treatment and discharge. Therefore, both RO and Ion Exchange are not economically feasable. Evaporation is not a viable option. Silver chloride and/or lead chloride precipitation are obviously not workable options. I have seen several references to Ultra HIgh Lime with Alumina Treatment but have not found a good description of how or if it works. Is there any other method of removing chlorides from water???? Better yet, is there a referance available that compares and contrasts the various methods on one text??????
Thanks in advance

Chloride Removal:
HPT Research, Inc. is presently engaged in a R & D project for the removal of salt from water. Excellent reductions of chlorides have been achieved in both bench top and pilot plant tests of food processing brine solutions. Between 90% to 94% reductions in chlorides and BOD have been realized in the pilot plant treatment of olive brine solutions. The process is presently being tested for possible use in the pre-treatment of ocean water prior to Reverse Osmosis Desalinization. Initial results indicate the HPT Salt Removal process has the potential of increasing the efficiencies and economies of Reverse Osmosis desalinization.
