  • What is Chemical Oxygen Demand (COD)?

    Chemical Oxygen Demand (COD) analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Specifically, it measures the equivalent amount of oxygen required to chemically oxidize organic compounds in water. Why Measure COD? COD is used as a general indicator of water quality and is an integral part of all water quality ...

  • What are the differences between Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)?

    Ask the expert: What are the differences between Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)? Answer: Both COD and BOD test methods aim to give an indication of the amount of pollution in a water sample. COD is the amount of oxygen required to chemically breakdown the pollutants whereas BOD is the amount of oxygen ...

  • Research experiences in microwave-assisted chemical oxygen demand determination

    The conventional COD determination through reflux method, although still much in experimental practice for water and wastewater analysis, is time consuming, complex and prone to a number of errors. A simpler, more rapid, environmentally benign but still precise method would hence be more attractive and is, in point of fact, a pressing need. Contextualised within the concept of Green Chemistry, ...

  • PeCOD Case Study – Industrial Waste Water

    Clean Harbors is an industrial wastewater treatment facility in Guelph, Ontario. The facility utilizes highly refined, chemical precipitation processes, which remove heavy metals, suspended solids, and organics to generate safe effluent for discharge into municipal sewer systems. Wastewater is treated to meet municipal discharge requirements for biochemical oxygen demand (BOD5). Since BOD is a ...

  • Incremental sanitation improvement strategy: comparison of options for Hanoi, Vietnam

    Urban sanitation issues should be tackled strategically, and may be addressed effectively when sewerage development is pursued in conjunction with complementary sanitation measures. Five sanitation improvement scenarios employing sewerage, night-soil collection-and-treatment (NSCT) system, and/or septic-tank improvement by annual desludging were analyzed from the perspective of COD loads, total ...

  • Real-time monitoring of membrane bioreactors with 2D-fluorescence data and statistically based models

    The application of membrane bioreactors (MBR) for wastewater treatment is growing worldwide due to their compactness and high effluent quality. However, membrane fouling, mostly associated to biological products, can reduce MBR performance. Therefore, it is important to monitor MBRs as close to real-time as possible to accelerate control actions for maximal biological and membrane performance. ...

  • Isolation, development and identification of salt-tolerant bacterial consortium from crude-oil-contaminated soil for degradation of di-azo dye Reactive Blue 220

    The objective of this study was development and characterization of a halophilic bacterial consortium for rapid decolorization and degradation of a wide range of dyes and their mixtures. The 16S rRNA gene analysis of developed halophilic consortium VN.1 showed that the bacterial consortium contained six bacterial strains, which were identified as Pseudomonas fluorescens HM480360, ...

  • How Shasun maximises the investment in it`s biological wastewater treatment plant

    At the Dudley Shasun facility we have a 7500 m3 biological treatment plant that can treat up to 36 tonnes of waste COD per day. Part of this capacity is utilised to treat up to 15 tankers per day of third party aqueous waste. The waste is very varied, covering everything from leachates at only 2000ppm COD to industrial waste at up to 500,000ppm COD. The Strathkelvin respirometer forms a central ...

  • Biological Monitoring Tools for Recycling Hazardous Effluents

     Abstract Increasing dependence on chemicals and rapid developments in chemical technology have practically triggered the growth of chemical industries in India. Globally, Basel convention guidelines are available for transboundary movement of hazardous wastes. However, at the national levels, health damage, resources losses and ecological impairment due to hazardous wastes indiscriminate ...


  • Correlating Biochemical and Chemical Oxygen Demand of Effluents – A Case Study of Selected Industries in Kumasi, Ghana

    Abstract   This work aims at establishing an empirical correlation between Biochemical Oxygen Demand (BOD5) and Chemical Oxygen Demand (COD) of effluents from selected industries in the Kumasi Metropolis to facilitate speedy ...


  • PeCOD – Petrochemical Industry - Case Study

    Optimizing process efficiency for petrochemical wastewater monitoring is a key step in achieving sustainable energy. Care must be taken to properly monitor and treat wastewater generated from petroleum refineries to ensure contaminants are not released into the surrounding environment. Fast, safe, and reliable detection technology is therefore highly sought after and enables plant operators to ...
