Compact sewage treatment plant CHC-OXIREC-C

biologicalactivated sludgecompact

The treatment plant for low-load activated sludge (extended aeration) with settling tank, compressor, diffuser grid and sludge recirculation system CHC-OXIREC-C is used to treat water of medium and large populations, to remove 80% to 90% organic matter (BOD5). This equipment in GFRP includes a system of oxygen supply and equalization of the mixed liquor through compressor and grid of fine bubble diffusers in EPDM, a compact settling tank and an activated sludge recirculation system through submerged pump. It includes an electrical panel board for electromechanical protection and programming. The treatment plant by low-load activated sludge (extended aeration) with truncated shape settling tank, compressor, fine bubble diffusers grid and sludge recirculation system CHC-OXI-REC-DEC is almost the same than the previous one, but for a higher organic matter removal (BOD5 ≥ 90 – 95%). It is achieved with the incorporation of a truncated cone shape settling tank with central feeding and Thompson perimeter canal. The nitrification-denitrification treatment plants are secondary treatments by low-load activated sludge, with biological nitrogen removal (nitrification-denitrification) and clarification process. Optionally, a phosphorus removal system is available. We find two models that differ from each other in the clarification process: the CHC-OXI-REC-C-ANOX treatment plant carries out its clarification process in a secondary compact settling tank and the CHC-OXI-REC-DEC-ANOX in an independent truncated shape cone settling tank.
