Biologically Active Filter Technology Applications For Wastewater Treatment Upgrade

By Mark Drake, PE (NC), LEED AP, Product Manager, Kruger Inc. (Veolia Water Technologies)

Wastewater treatment facilities are subject to many different drivers for completing upgrades. Among the most prevalent drivers is a need to keep current with ever-changing, and increasingly stringent, environmental regulations. These regulations frequently require upgrading a primary treatment facility (i.e. only screening and primary clarification) or secondary treatment facility (biological treatment for removal of BOD and TSS) to tertiary treatment and the removal of BOD, TSS and Total Nitrogen (TN).
