DWS BVBA
Biological Biogas Scrubber
FromDWS BVBA
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.

- Acid proof tank construction to ensure the longevity of the installation;
- Proven on many installations media filter applied for the optimal surface area for bacterial growth and low-pressure drop of the filter;
- Low footprint of the treatment unit;
- The only waste after the treatment is liquid sulfate solution that can be discharged into the anaerobic effluent stream – leaving no hazardous secondary waste behind;
- The Operator Control Station of the unit is delivered as a convenient, pre-mounted skid;
- The hydrogen sulfur concentration in the treated biogas stream is suitable to fuel turbines and other equipment.
Our team can assist you in both commissioning and start-up of the unit.
