  • Biodegradability of Dissolved Organic Nitrogen: Adaptation of the BOD Test

    To prevent eutrophication in receiving waters, many astewater treatment plants are being firected by regulatory agencies to achieve very low levels of total nitrogen (3-4 mg/L TN or lower) in the effluent. Dissolved organic nitrogen (DON) component is included within these total nitrogen limits. The regulations assume that DON is completely biodegradable, and therefore needs to be included in any ...

  • Quaker oats uses skimmer to reduce wastewater BOD

    The Quaker Oats plant in Peterborough, Ontario, Canada produces some seven million cases of Harvest Crunch® cereal and cake mixes annually. In the process, residue from the conveyors, dryers and other processing equipment ends up on the floor. Periodic equipment washdowns add water to the solid and liquid residue, which contains edible fats, starches and sugars. During house-cleaning operations, ...

  • 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 ...

  • Pilot testing of a membrane bioreactor for metals removal

    The City of Davis, California (City) Water Pollution Control Plant (WPCP) is facing stricter effluent permit requirements and compliance with the California Toxics Rule (CTR) effluent limitations. The impact of these requirements will necessitate upgrades to the existing WPCP to include conventional secondary and tertiary processes to control the discharge of biochemical oxygen demand (BOD), ...

  • Biodegradability of industrial textile wastewater – batch tests

    Following new trends we applied oxygen uptake rate (OUR) tests as well as long-term tests (in two batch bioreactors systems) in order to assess the biodegradability of textile wastewater. Effluents coming from a dyeing factory were divided into two streams which differed in inorganic and organic contaminants loads. Usefulness of the stream division was proved. Biodegradation of the low-loaded ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Chemical and Biological Treatability Testing of an Industrial Leachate

    Remediation efforts are ongoing at the Avtex Fibers Superfund Site in Front Royal, Virginia. As part of the future remediation of several surface impoundments used for viscose waste disposal during plant operation, it may be necessary to extract contaminated leachate and groundwater for ex-situ treatment and discharge to the Shenandoah River. This waste stream contains high concentrations of ...

  • Efficient Waste Water Treatment

    Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

  • Beyond the barriers of water reuse

    Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked. An answer can be found in the ways that we apply membrane bioreactor (MBR) technology. As one of the most central components for water ...

  • 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 ...

  • An Investigation into the Water Quality of the Charleston Peninsula Storm Drains

    Since the late 1980’s, the South Carolina Department of Health and Environmental Control (SCDHEC) has expressed concern over extremely high fecal coliform counts found in several of the many storm drains that discharge from peninsular Charleston (City of Charleston, 1998). Although the City of Charleston is responsible for the fifty-plus storm drains, Charleston Water System wants to determine if ...

  • Using UV Fluorescence technology to monitor for organic pollutants in Flood Water

    For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments.  Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters.  There is however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of ...

  • Development of a water quality assessment model: a water quality assessment model based on watershed characteristics by non-linear regression

    Here, a water quality assessment model (WQAM) is developed by non-linear regression as an alternative to physical watershed modeling in South Korea. Three cases and 10 scenarios are applied and reviewed to determine the most appropriate WQAM. The three cases are: (1) the area size allocation of sub-watersheds, (2) the watershed imperviousness ratio, and (3) the combination of the area size and ...
