Construction of the HERBST-Filter


The microorganisms grow in the HERBST-Biofilter on a special HELATROP®-substrate which is flown through by the discharged air that has to be purified. The high effectiveness of the HERBST-Biofilter at a loaddition w need of floor space can be achieved by an ideal process conduct of the biological decomposition. The growth of the microorganisms is e.g. advanced by the of custom-designed nutrients. The inner operating parameters such as micro-organism population, pH-value, nutrient accommodation and pollutant load are adjusted to each particular case at the same time. Despite the intensive biological decomposition in the HERBST-Biofilter the HELATROP®-substrate is not subject to any aging. The usual change of the substrate can thus be omitted.
