DEVOUR contains a synergistic blend of new bacterial strains which have been scientifically developed to combat compounds and chemicals present in waste water effluent. Unlike any other bio-formulation, DEVOUR contains bacterial strains which actually digest difficult compounds such as detergents, paper, oil, grease, hydrocarbons, phenols, etc. DEVOUR's formulation improves the performance of septic tanks, lagoons, activated sludge, trickling filters and water holding basins. These cultures provide the best protection you can buy for waste water applications. It is available in 25-pound containers or in 30 1-pound packets.
