SEEDING OF BRACKISH WATER IN A SPRAY-FILM EVAPORATOR
Abstract
When operating on many brackish waters, sea water distillation equipment becomes inoperative in a short time because of heavy deposits of calcium sulfate scale. Investigations are being made to evaluate a calcium sulfate crystal-seeding method for prevention of this scale formation in evaporators. The report covers tests performed at the Office of Saline Water, Roswell Test Facility to investigate the use of crystal-seeding techniques to inhibit the formation of sulfate scale in a horizontal-tube, spray-film evaporator. These crystal-seeding techniques were evaluated on raw well water and well water with silica removed. A control test without crystal seeding was also conducted. The results of these tests indicate that on all waters tested, the crystal-seeding process can inhibit the formation of evaporator scale in a horizontal-tube, spray-film evaporator. (Author)
