Activated carbon filtration plant

air

Bioscrubbers are used for the biological purification of exhaust air and exhaust gases. For this purpose, a physical gas scrubber is combined with a biological activation unit. First, the raw gas is brought into contact with a cleaning solution in the absorber. In a second step the pollutants transferred to the scrubbing solution are decomposed by microorganisms to carbon dioxide and water in a regeneration reactor. The regeneration reactor corresponds to the activation tank in the wastewater treatment plant. Nutrients required for bacterial growth as well as acids and alkaline solutions for adjusting the optimal pH-value are dosed in. The upstream gas scrubber prevents aggressive pollutants in the exhaust gas from damaging the microorganisms used for cleaning. Two-stage process for odor elimination and exhaust air purification ABIONIK bioscrubbers can be used at air pollutant concentrations of over 100 mg/m3 – depending on the water solubility of the pollutants. We have experience with washing the following groups of substances phenols sulphur compounds carboxylic acids and carboxylic acid esters aldehydes alcohols Absorbers can basically be designed as single or multi-stage units. The decisive factor for the design is a phase interface that is as large as possible to ensure the longest possible residence time of the air pollutants with the carrier material of the biology. In the case of easily degradable substances, a regeneration reactor can be dispensed with, provided that the absorber sump is sufficiently dimensioned. Sedimentation tanks are provided with active aeration if required.
