COD removal Applications

  • COD reduction

    Ozonation for biorefractory COD removal

    By Newland Entech Europe based in Villaviciosa de Odón, SPAIN.

  • BOD and COD Removal

    Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD / COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. These include: Predigestion of wastewaters which contain moderate to high levels of compounds that are toxic, inhibitory, or recalcitrant to biological treatment (e.g.,...

  • Premium

    Anaerobic water purification systems for anaerobic COD removal

    In anaerobic treatment, bacteria convert organic compounds (COD) to biogas in an environment without oxygen. Not only do the bacteria remove contaminating compounds from the effluent, thereby reducing discharge costs, they produce green energy at the same time.

  • Premium

    Anaerobic water purification systems for aerobic COD removal

    In an aerobic treatment system, air is injected which is used by aerobic bacteria to convert BOD to carbon dioxide and water.

  • COD Reduction

    Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water. In wastewater treatment, it indicates the efficacy of a treatment process and is expressed in milligrams per litre (mg/L) or parts per million (ppm). Removing certain fractions of COD in waste streams can be particularly challenging, especially to levels safe for discharge to the environment.

  • Industrial wastewater treatment for industries

    MIOX is the lowest cost supplier of chlorine for disinfection and oxidation of wastewater prior to discharge. Mixed Oxidant Solution (MOS) chemistry is more effective at biofilm control, Biochemical and Chemical oxygen demand removal (BOD/COD), breakpoint chlorination of ammonia and hydrogen sulfide (H2S) removal.

  • Filtration technology for Wastewater treatment industry

    THE AQQA FILTRATION TECHNOLOGY IS USED IN WASTEWATER TREATMENT TO: seperate the mixed liqour from the clear water phase in Membrane Bio Reactors (MBR). remove bacteria and virus from wastewater. remove particles (and attached organic and inorganic material) from any wastewater, thus reducing the freight of chemicals and the charges for the COD load (e.g. in Germany).

  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is...
