BBF Biofiltration

Primary Treatment

 
 
 

Repurpose your old primary clarifiers to increase capacity or upgrade your process.

BBF has a 65-80% smaller footprint than primary clarifiers

At the 66MGD Jungnang Treatment Facility in Seoul, South Korea, the footprints shrank for primary treatment by 80% and main treatment by 50% after the installation of the BBF Biofiltration system.

  • Up to 50% higher BOD removal than settling

  • 10% total backwash volume at 1min/3hr cleaning rate

  • Never worry about primary sludge carryover again

  • No air scour necessary – energy savings

Zero chemicals, low energy

Can be installed underground for unparalleled odor control and unique land repurposing

Patented new media has the highest solids loading rate of any biofiltration process in the world

Gravity-based, zero-energy backwash uses only process water for cleaning

The Jungrang municipal treatment facility is one of the biggest in Seoul. This plant has replaced primary clarifiers in its 66MGD treatment train with underground BBF primary filters, and added 132 MGD in additional BBF biofilters to manage wet weather flow. This plant has already met and exceed its treatment targets for over 6 months at full-scale.
