The low-load activated sludge treatment plant (extended aeration) with high-efficiency fixed culture CVC-OXIDEP-TC is usually used to treat the water of small towns and is certified according to EN 12566-3 Standard.
This equipment manufactured in GFRP has a system of oxygen supply and equalization of the mixed liquor through a compressor and a fine bubble diffusers grid in EPDM, a fixed bed of plastic material, for fixation and growth of the biomass, a recirculation system of activated sludge through Airlift and a truncated cone shape settler with central supply and Thompson perimeter canal. The CHC-OXIDEP model is exactly the same, but does not include the truncated shape settler.
