BOD & COD Applications

  • Respirometer Applications

    Measurement of the aerobic biodegradability of plastic materials (US Standard ASTM D5338, European Standard ISO 14855)

  • TOC Correlation to BOD or COD

    Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement does not allow an operator to use the data for process optimization and. although COD requires less time than the BOD, its analysis includes the use of hazardous chemicals and has no constant analysis capability.

  • 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.

    Biological waste water treatment plants solutions for brewing industry

    The brewing process generally generates unique, high-strength waste water as a by-product. The waste water typically has a high concentration of Biological Oxygen Demand (BOD) form the carbohydrates and protein used in brewing beer. Brewery waste water usually has a temperature of > 25 °C.

  • Biological wastewater processes for petrochemical

    This wastewater typically contains a lower biochemical to chemical oxygen demand.  We determine biodegradability of each waste stream and the presence of toxic or inhibitory compounds.

    Wastewater solutions for the industrial effluent pollution management

    Problem: Industrial manufacturers face stringent regulations for discharging wastewater to the environment and municipal sewer systems. Biochemical Oxygen Demand (BOD) is a primary concern for many discharge limits, as wastewaters high in BOD can have adverse impacts on the aquatic environments by leading to oxygen depletion. In some cases, as a means to supplement BOD, it is also desirable to monitor chemical oxygen demand (COD) of industrial effluents. Both of these tests, are time and labour intensive reducing the frequency at which they can be measured for a given effluent.

    Water Testing for Environmental Applications

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many cases, there are restrictions on wastewater that is discharged to city sewer systems or to other publicly owned treatment facilities. Many jurisdictions even restrict or regulate the runoff of stormwater — affecting not only industrial and commercial land, but also residential properties as well.

    Online water analysers for process water and waste water industry

    Process and waste water are the most challenging water for instrumentation. Mostly, these water are characterized by highly fluctuating loads, very high salt concentrations as well as a high particle density. Hence, the accurancy and speed of measurement depends on the measurement system itself and the used oxidation technique. Obviously, application-specific analysers provides huge advantages against standard analysers, that are used for every application.
