It is stuffed to efficient use of heat from steam to evaporate the waste water. Water is heated in a series of SS 316 Vessels each one held at a low pressure than the last. Here multiple effects relates to the sequence of evaporators in which the pressure depleting progressively from one unit to the unit at next stage so that the vapor from each unit except the last unit heats the liquid in the next unit.
The multiple-effect evaporators consist of one or more evaporator units to save amount of steam used, which is concentrated and condensed only at the first-effect heat exchanger. The total volume of water get evaporated at the first-effect evaporator body is condensed at the second-effect heat exchanger, which also provides energy to the second-effect evaporator body and this process continues for rest of the effects except the vapor from the last effect which flows to a condenser.
The last-effect evaporator body is calibrated at a very high vacuum with an air ejector (steam-jet) through mechanical vacuum pump. This drive force prevents scale of pressure to be drop to be dropped among the multiple effects.
The Evaporators with more effects require less pressure and steam. We can say a five-effect evaporator requires 25 % of less steam than a single effect evaporators.
