Waste air cleaning


  • Scrubbers with countercurrent and semicrossflow (SXF-scrubber) air flow for removal of HCl, Cl2, H3PO4, HF, O3, H2S, NH3, SO2 and organic in water soluble acids from the waste air.
  • NOx removal from the waste air is operating in alkaline pH range for HF removal from the waste air combined with pH regulation. NOx in gasoues phase will be removed from the waste air with redox potential controll as well as dosing of chlorine dioxide for oxidation of NOx to NO3- and will be final neutralised by base.
  • Odors in the waste air occuring in composting, effluent sludge treatment, pharmaceutical industry and municipal sewage plant will be removed with innovativ and new developed process for odor removal. That process is based on scrubbing and adding of sulfuric acid, hydrogene peroxide and chlorine (III) acid to the make up water. That scrubbing process can replace biofilters and needs a lot of less space than biofilter.


  • Stripper for CO2, toluene und xylene removal from the water.


  • Misteliminators for removal of droplets and aerosols up to 2 ┬Ám, for instance Cr6+, H2SO4, HCl and NH4Cl aerosols.


  • Zeolitefilter for removal of inorganic and organic contaminants from the waste air
