The AGAR© is a fixed biofilm moving bed process that uses suspended biomass carriers with extended surface area for biofilm growth, along with carefully designed reactor hydraulics. The aerobic AGAR® process can fit in most activated sludge systems and can be implemented in a variety of configurations. The Attached Growth Airlift Reactor technology combines a unique fully open and fully protected biomass carrier with a highly efficient aeration and mixing design. This results in superior effective surface area for biomass growth and optimal oxygen transfer
The unique AGAR® Aeration design is using either fine or coarse bubble diffusers to create a double role motion in the reactor. The double role motion, create constant collisions between the carriers and keeps a thin and viable biofilm on the carriers. Due to the unique aeration design – double roll pattern, in most cases, no additional air is required for the rolling motion and air supplied to fulfill the biomass demands is sufficient for both biological activity and mixing.
