Municipal Wastewater

Tertiary Treatment


A vast majority of wastewater treatment facilities in the United States, most of which were built decades ago, are not able to meet low nitrogen discharge limits. Pollution resulting from the operation of these plants has therefore led to severe environmental problems. The limitations of these existing facilities present a serious technological hindrance for water reuse applications requiring nitrogen removal, including groundwater replenishment.

Proven to function effectively in filtration, BBF is capable of simultaneously removing nitrogen while occupying equal or less space compared to traditional tertiary filtration options such as sand filters. This compact footprint makes BBF an ideal choice for retrofitting outdated wastewater facilities looking to update their technology with nitrogen removal processes under space limitations.

Treated wastewater is easily accessible and can be stable in quality and quantity, making it a high value alternative water resource. In order to reuse treated wastewater, removal of nitrogen and solids is an essential step before advanced wastewater treatment process.

BBF Benefits for Tertiary Treatment

  • Further treat the nitrogen from secondary treated water

  • Can be operated under various water quality conditions and can ensures stable water quality through its filtration function (Turbidity <2 NTU)
