Application: PURON® MBR Effectively Removes Phosphorous

Controlling phosphorous discharge is a key factor in preserving surface water quality. Today, new legislation and regulations strictly limit phosphorous discharge into sensitive waters. Typically, conventional phosphorus removal processes using biological and tertiary treatment steps are capable of providing effluent total phosphorous in the range of 0.5 to 1 mg/L, levels which exceed many regulatory requirements.

Municipal wastewater treatment plants are now looking to membrane bioreactor (MBR) technology as a solution for phosphorous removal. MBR technology is already being adapted at a rapid pace due to two main advantages compared to conventional biological wastewater treatment—significantly improved effluent quality and a substantially smaller footprint.
