Postnum: 262 EntryID:1172
We have a problem of treating an effluent containing about 80,000 ppm of sodium chloride, 20,000ppm of sodium sulphate and an organic resiue of 0.1%(hydroxyquinoline derivatives). The solution is dark brown coloured. Can we convert this into useful salt of sodium chloride?

It is generally very difficult to precipitate salts from water without distillation. It would be even more difficult to separate the NaCl out from the NaSO3 in the process. I have worked with OMI and Crown Environmental in the past with waste water issues as both companies specialize in waste water treatment. OMI does mainly municipal waste, Crown concentrates on industrial wastes.
