AGAR® (Attached Growth Airlift Reactor) Biological Treatment Process

The unique AGAR process is an innovative biological treatment process that uses thousands of special carriers designed to create an enormous total surface area for biofilm growth – enhancing your wastewater treatment process without expanding your footprint.

The process can be operated as either a fixed-film only or an integrated fixed-film activated sludge (IFAS) process.

What this means to you:

Improved oxygen transfer; reduced operating cost
Reduced maintenance; elimination of plugging; reduced cost
Allows for expansion/upgrade without additional tankage; reduced cost
Nitrogen removal without increased hydraulic retention time
Fixed-film biomass is attached to carriers designed to remain in the aeration basin even under hydraulic upset conditions; due to biofilm layers on the media, toxic upsets typically do not affect all active biomass and recovery is much quicker than with suspended growth systems.
