Next Filtration Next-F.O.G.Stop

Next Filtration’s Next-F.O.G.Stop is molecular kinetic technology that optimizes aerobic MLSS operation and increases wastewater throughput up to 40%. It promotes biostimulation of indigenous microorganisms through the uncoupling of microbial metabolic pathways. Trials demonstrate that it amplifies the metabolic rate of organic carbon degradation and lowers the amount of biomass produced. The excess carbon is metabolized and off-gassed in the form of carbon dioxide rather than being converted to biomass or biofilm. Specifically, results show feeding it into the inlet stream of municipal and industrial wastewater facilities led to a decrease of biological oxygen demand and total suspended solids, and an increase of dissolved oxygen. Indirectly, this leads to reduced energy consumption, due to reduced aeration blower rates. 800-783-0310;
