The treatment plant with biomembranes CHC-OXI-MBR is a secondary treatment by means of membrane bioreactor (MBR), optionally with biological nitrogen elimination (nitrification-denitrification). This biological treatment with separation of biomass from clarified water is carried out by ultrafiltration membranes at atmospheric pressure (nominal pore diameter <0.1 μm). The CHC-OXI-MBR achieves high yields in the removal of organic matter, suspended solids and ammonium (BOD5: 99%, COD: 95%, N-NH4 +: 82%, SST: 99%, fecal coliforms: 99.9%). It is composed of Salher equipment manufactured in GFRP certified by an external body, with strict quality controls in its production process, which are also compact, modular, highly efficiency and easy to install and commission. The advantages of these treatment plants compared to others equipment, Salher brand, are: Exceptional quality of the effluent. Water quality for water reuse, according to regulation RD1620 / 2007. Effluent 100% free of viruses, bacteria and other pathogens. Reduction of the necessary area compared to traditional technologies: 65 – 75%. Elimination of the secondary settling tank and reduction of the volume of the biological reactor. Substitution of the secondary decanter by ultrafiltration membranes. Technology with perfect separation of clarified water and sludge (liquid fraction of mixed liquor). Elimination of problems associated with the settling of sludge. Greater flexibility to face peak flows and contaminating loads. Absence of odors. No bulking problems. Lower production and greater stabilization of sludge. Increase of sludge ages and decrease of mass loads.
