Facultative bacteria blend

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, the blend releases very high numbers of 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. The product is capable of de-nitrification and phosphorus removal without the need for separate processes and typically eliminates noxious odor within a week of application.
