A new twist to optimize biofilm treatment for lagoon augmentation

DATE POSTED: July 2, 2019


As published in Western Canada Water – Spring 2019

Biofilm, or fixed-film processes, are not new to wastewater treatment—the approach has been used successfully for decades — and long before activated sludge was introduced.

However, not all biofilm technologies are the same and many experience challenges in achieving low operating costs and optimizing system performance in difficult conditions such as sudden increases in loading, cold water conditions and year-round removal of nitrogen. 

Recent developments in fixed film media, system design and aeration have produced a low-cost, low-energy, low-maintenance process that is installed directly into a treatment lagoon to increase capacity and performance without expanding plant footprint.  

Developed by Bishop Water Technologies, the BioCord™ Reactor system is a fixed-film biological treatment process that is like a condominium for bacteria. Each reactor supports densely arranged, twisted loops of polymer fibres that provide a massive surface area on which preferred, naturally occurring bacteria can thrive.

Read the full article to learn how an optimized BioCord system can help operators overcome many operational challenges.
