Acidic Waste Water Treatment

Acidic wastewater is an invariable by-product in the surface finishing of glass and metal. Neutra‘s state-of-the-art wastewater neutralisation units help protect the environment and recover valuable materials.
The process wastewater is neutralised through addition of lime milk to precipitate the acidic constituents, after which it is pumped into a receiver tank and then pressed through a cloth on a filter drum for separation into solid and liquid fractions. The liquid fraction is then either piped to an industrial process water tank for use in further neutralisation cycles or discharged into the sewage system, while the filter cake made up of solid constituents can be recycled or dumped at hazardous waste landfills. Depending on requirements, Neutra supplies semi- and fully-automatic units complete with an integral control system.
