The TETRA® ColOX™ system is an advanced aerobic biological treatment system which combines the best elements of activated sludge (suspended growth) processes and trickling filter (attached growth/fixed-film) systems with innovative design features to achieve superior performance. Configured as a Submerged Packed Bed Reactor, the ColOX system utilizes both fixed-film and suspended growth biomass, offering greater efficiency, operational reliability and versatility than any other aerobic biological treatment process.

TETRA ColOX aerobic bioreactor systems provide superior nitrification, BOD reduction and filtration of suspended solids for water and wastewater applications where aerobic biological treatment is used.
