  • 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), ...

  • 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 ...

  • Compost Leachate Pond Bioremediation Case Study - Composting Facility, Northern California

    Our client runs a composting facility that receives green waste, food waste and other compostable material from residential and commercial sources, to create rich, black compost Challenge As part of the facility, the compost leachate pond has repeatedly experienced problems with the incoming influent high chemical oxygen demand (COD) and ...

  • Flavour Industry Wastewater Management Case Study

    This study is carried out to propose an appropriate treatment technology for wastewater discharged from a flavor production factory. Industrial wastewater discharged from this factory ranges between 50–70 m3/d with an average value of 60 m3/d. The major source of pollution in this factory is due to cleaning of the vessels therefore the treatment has been carried out on the end-of pipe wastewater. ...

  • Organic matter degradation in a greywater recycling system using a multistage moving bed biofilm reactor (MBBR)

    Greywater is an important non-conventional water resource which can be treated and recycled in buildings. A decentralized greywater recycling system for 223 inhabitants started operating in 2006 in Berlin, Germany. High load greywater undergoes advanced treatment in a multistage moving bed biofilm reactor (MBBR) followed by sand filtration and UV disinfection. The treated water is used safely ...

  • On-site treatment of domestic wastewater using a small-scale horizontal subsurface flow constructed wetland

    A small-scale horizontal subsurface flow constructed wetland, located in North Greece, was designed and constructed to treat wastewater from a single-family residence. A three-year monitoring program was undertaken to evaluate the performance of this system. The monitoring campaigns were organized every 7 days. Water quality samples were collected at the inlet, at intermediate points (i.e. at the ...
