  • Organics Monitoring (TOC)

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small. Organic Matter Organic ...

  • PeCOD® Case Study: 15 Sewer Use By-Law Monitoring: Batch Release Tracing City of Austin, Texas

    Municipal wastewater treatment plants are designed to process a calculated range of organic loading in the raw influent. The calculation of this loading is based on characteristics of the plant’s region, such as population and industry type. Organic loading is most often quantified by the concentration of parameters such as Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Rapid Monitoring of Municipal Wastewater Primary Effluent - Case Study

    The primary effluent of a Municipal Wastewater Treatment Plant (MWWTP) is monitored to understand organic loading going to the next stage of treatment, the activated sludge process. This process removes organics via consumption by microorganisms living in the sludge. Knowing the composition of incoming primary effluent is important to prevent organic overloading and improve process optimization ...

  • Relationship between land use and water quality in a small watershed in South Korea

    Recent research and monitoring undertaken by various institutions have emphasized measurements of river-water quality. Based on the results, government agencies have set guidelines to improve river-water quality management. However, the relationship between water quality and land use/land cover (LULC) has not been examined closely in South Korea to date. This study investigated this relationship ...
