Seawater evaporator
WebThe RO process involves the use of pressure to force the seawater through a semi-permeable membrane for the removal of sodium and chloride. The process initially involves pre-treatment by using any of the methods such … WebEvaporator pumps. The unevaporated seawater in an evaporator gradually becomes a concentrated brine and, like the early steam boilers with seawater feed, this brine must be intermittently blown down every six to eight hours and dumped overboard. [5] Early evaporators were simply mounted high-up and dumped their brine by gravity. [1]
