Wet scrubbers
Wet scrubbers
- Physicochemical treatment system
- Especially effective for the elimination of water-soluble gaseous pollutants derived from sulphide (hydrogen sulphide, mercaptans) and from nitrogenous (ammonia, amines)
- Lower initial capital investment than biological technologies
- Small footprint compared to biological technologies
- Low VOCs abatement
- Legalization of chemical reagents storage required according to APQ regulations
- Continuous or discontinuous operation
- Requires qualified operators
- The overall odour elimination efficiency can be improved by connecting a polishing unit in series (conventional biofilter or activated carbon unit)
- Sectors: urban and industrial wastewater treatment plants, MSW treatment plants, pharmaceutical and chemical industries
