SaltMaker VapComp

Mechanical Vapor Recompression (MVR) Evaporator

Saltworks’ VapComp and other MVR evaporators require only electrical power to operate. You may already be reducing your brine volume with membrane systems, an MVR evaporator can help you to take the next step in brine management.

Introducing VapComp

MVR evaporators use a vapor compressor to evaporate brine and condense distilled water. They offer two primary advantages: they only require power to operate (so there is no need for a gas line connection or heat) and are compact. They generally come in two types:

  1. Falling film: wastewater falls down a heated tube, with vaporization occurring on the tube surface. These evaporators are intended for cleaner waters, with less scaling potential.
  2. Forced circulation: wastewater is heated in a high circulation rate heat exchanger, and evaporates in a vessel, reducing the risk of scaling on heat exchanger surfaces. Forced circulation evaporators are intended for more challenging waters, and when making solids.
