Gas scrubber for deodorization

When neutralising or decontaminating wastewater or sludge, odours arise which are caused by hydrogen sulphides, amines, mercaptans or other organic gas compounds. These gases become a significant nuisance.

VSS-Umwelttechnik develops systems which are individually dimensioned according to the respective gas components and concentrations. Wash-out of the gases is effected via oxidative gas scrubbing. Where required, multistage systems are also applied (see illustration).

Employment of our systems leads to the elimination of odour nuisances, the TA air limit values or other legal requirements are met.
