The anaerobic digestion process naturally lowers the BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand) in the effluent waste stream. Depending on the waste stream, the typical BOD & COD reduction levels achieved are over 90% of the original levels. The TSS (Total Suspended Solids) levels of the waste stream are typically reduced over 50%, resulting in significant wastewater reduction.
Clean water is also a byproduct of BioStar’s nutrient recovery system. This wastewater reduction means waste is diverted from sewage treatment facilities and landfills. Depending on the waste stream and the amount of sewage treatment surcharges that are being assessed by the local municipality, food processors in particular can pay for the majority of a BioStar Organics facility by simply reducing or eliminating these surcharges.
Reducing oxygen-demanding organics in agricultural wastewater is an important step in maintaining our ecosystem’s water quality. These organics, as well as nitrates, remove oxygen from the water and kill fish and other beneficial aquatic life. BioStar’s manure anaerobic digestion offers a responsible way to manage agricultural waste.
