Abstract:

A large malting company, located in Minnesota, utilizes a sequential batch reactor (SBR) to treat incoming wastewater. The wastewater treatment facility, operated by USFilter Operating Services, treats approximately 1.5 MGD of their 1.9 MGD total effluent pursuant to the discharge limits of the operating permit. The treated effluent is discharged to the Minnesota River, with the remaining untreated wastewater and the waste activated sludge (WAS) being discharged to the municipal sewer line. WAS is stored in an aerobic digester for 5 – 7 days prior to being discharged to the municipal sewer. The goals of the study were to determine, if the amount of sludge (volume and dry pounds) could be reduced by 30% and if the amount of aeration required throughout the process could be reduced as well.

Advanced BioCatalytics, Corp. (ABC) has isolated a biologically active cellular fraction, which combined with surface-active agents, leads to an effect similar to the uncoupling of microbial metabolic pathways. This ‘Uncoupling Composition’ (Accell™) has the demonstrated ability to significantly increase the metabolic degradation of organic contaminants by indigenous wastewater microbes, without concomitantly increasing the amount of biomass or biofilm.
