Treatment of emissions from surface treatment processes

Surface treatment processes can emit pollutant substance’s (ex. solvent evaporation from paints after pigment drop off)

Air Clean provides capture and treatment systems for air emissions utilizing either conventional technologies (scrubber, activated carbon, combustors) or biological technologies.

The latest multi stage biotrickling biological technologies (MónaShell®) are able to remove in a biological way a large numbers of solvents. The efficiency of the biological systems is dependent on the solubility and the bio-degradability of specific chemical compounds in the airstream. By optimising process conditions, low solubility compounds can be successfully treated using biotrickling filters very often in multi stage biotrickling filters.

Every application has to being studied to choose the best technology suited for each case. In general, for removing low concentrations of pollutant on intermittent applications activated carbon and chemical oxidation systems offer the best solution. Whilst for high concentration of pollutant’s thermal oxidation offers the best solution specially in cases which pollutants have a sufficiently high concentration to provide auto combustion without the requirement for supplementary fuel. Biological systems are useful for low to mid-range applications (biofilters generally for high volume low concentration application while biotrickling filters are more commonly used on lower volume higher concentration airstreams).
