A wastewater evaporator is a device that removes water from liquid effluent by turning it into
vapour and leaves pollutants behind. A wastewater evaporator’s purpose is to minimize the
volume of waste products and do wastewater recovery. Evaporation technology can be used to
reclaim precious items or separate dangerous materials through wastewater flows. It can be used
to concentrate or remove salts, other harmful elements, and heavy metals from a solution.
Categories of Evaporation
Evaporators have diversity of sizes and shapes. The
parameters that are used to classify evaporators are
following:
• The layout of the heat exchanger
• The technology utilized to transmit energy
towards the solution.

WORKING
Heat is transported from condensing steam toward a
fluid at low temperature over a metallic heating
surface, which drives the evaporation process.
This leads in rise in the concentration of solutes.
