Multi Effect Evaporator (MEE)

A multiple-effect evaporator is an apparatus for efficiently using heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used to heat the next, and only the first vessel (at the highest pressure) requires an external source of heat and thus saves energy and overall operational cost.

MEE is widely used for product concentration and has now been used for recovery of water from wastewater which can be reused for industrial operations thus reducing overall fresh water demand of the industry leading zero liquid discharge and sustainable development.

Our systems are energy efficient as they utilize waste heat, multiple effects, mechanical vapor recompression (MVR) and/or thermal vapor recompression (TVR). We offer Material of Construction (MOC) viz.  CS (IS 2062 Gr A/B, SA 516 Gr 60/70, BQ), SS 316, SS 304, SS 316 L, SS 304 L. SS 310, TITANIUM, HASTALLOY and combinations as per effluent characteristics and industry requirement.

We have successfully installed wastewater treatment plants inclusive of Multi Effect Evaporator for water recovery for ball bearing, and pharma formulation industries.
