Fixed-Bed Biofilm Activated Sludge (FBAS)

Fixed-Bed Biofilm Activated Sludge (FBAS) is a type of Integrated Fixed Film Activated Sludge (IFAS) system that leverages the use of various natural AND artificial media to provide a habitat for a diverse fixed-film bacterial culture which metabolizes the contaminants in wastewater.

These populations of organisms live in an attached form on fixed bed media inside the reactors, as opposed to being in constant motion as is the case with conventional solutions such as Activated Sludge or MBBR.

 

Providing a stationary habitat allows an incredibly diverse and robust biofilm to grow and thrive inside the reactors, ultimately offering  significantly improved nutrient removal, energy efficiency, and resiliency, all in much less space than conventional approaches.

With nearly two-decades of experience in the development and design of fixed-film wastewater treatment solutions, Organica’s FCR (Food-Chain Reactor) represents the best-of-breed in FBAS wastewater treatment plants (WWTPs).
