Sewper Rx Sludge Reduction System

Source: RELIANT Water Technologies


Sewper Rx is a patented polymicrobial blend of facultative bacteria specifically selected for their ability to degrade organic waste and eliminate noxious odor. When it is added to a waste stream, it releases very high numbers of motile bacterial cells that immediately begin degrading or breaking down protein, carbohydrates, fats, oils, grease and cellulose. These bacteria reproduce very rapidly, doubling in number every 24 minutes. Sewper Rx is capable of de-nitrification and phosphorus removal without the need for separate processes and typically eliminates noxious odor within days of application. The by-products of this bioaugmentation treatment are water, CO2 (which gases off) and some remaining inorganic solids (ash).
