DWS BVBA products

To effectively condition high biogas volumes of biogas low in hydrogen sulfide (H2S < 1%) DWS advises the application of our highly-effective biological scrubber. This biotrickling filter utilizes chemolithotrophic bacteria to oxidize the hydrogen sulfide into sulfur or sulfate at a low capital cost and without large energy inputs, as it can be in case of membrane separation or chemical biogas scrubbers. For the continuous operation, the biofilter requires only nutrients (nitrogen, phosphorous and potassium) and atmospheric air.
