Since treating waste water is not a new occurrence many sites already own an aerobic treatment plant. Disadvantages like high energy consumption and sludge production are no new issues to many customers. With the DACS retrofit we can easily upgrade your treatment plant. An existing aerobic tank can be converted into an anaerobic DACS reactor within very limited time frame. By upgrading the anaerobic treatment you can multiply your treatment capacity. Sludge disposal is brought to a minimum. Instead of consuming huge amounts of energy the DACS will produce lots of energy from waste water.
