Multi Effect Evaporator commonly uses sensible heat in the condensate to preheat liquor to be flashed. In this unit high TDS reject water is heated and circulated to increase the salt concentration. It is very expensive to operate as it requires steam for working so we pass only 2-3% of effluent to MEE.
Low steam consumption
Low power consumption
MEE can operate on any hardness value
