Description

Wet scrubber is a necessary equipment in Aluminium melting or aluminium recycling plant.

A Wet Scrubber is an air pollution control device which uses a liquid to remove contaminants from a gas stream.

The removal process is achieved by bringing the gas stream into contact with the scrubbing liquid, which facilitates mass transfer of the contaminants into the liquid. When the water is recirculated, addition of fresh water is necessary to purge contaminants and replace evaporation losses. Fresh water may be added to the recycle continuously or periodically
