Biosettler wastewater treatment

Description:

Scientists at the QUESTOR Centre, Queen's University of Belfast have developed a product enabling improved wastewater treatment. The BioSettler™ enhances the final settlement process in wastewater treatment plants allowing additional treatment to occur, aiding compliance with discharge consents to surface waters.

Settlers (also called clarifiers or settlement basins) are an integral part of almost all biological treatment plants and function to remove suspended solids by sedimentation. The BioSettler™ allows for an improved form of final settlement for wastewater that will allow additional aerobic treatment to occur during the period of settlement or clarification.

Benefits

•       Utilises the retention time of final stage settlement allowing aerobic treatment to take place within same settlement environment.

•       Aerobic biological treatment is preferably facilitated by bubble-free aeration supporting a large biomass density for effective wastewater treatment.

•       Settlement is improved, BOD is reduced and nitrification/de-nitrification can be achieved in a smaller sized tank.

•       Capital, space and civil costs are greatly reduced when compared to existing solutions to the problem – both new and retrofits.

•       Low energy requirements compared to membrane bioreactors.

Applications

•       Large-scale municipal or industrial wastewater treatment plants.

•       Small-scale sewerage treatment tanks.

•       Can be adapted to existing plant refits or upgrades to improve settlement efficiency.
