  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Pathway‐based approaches for assessment of real‐time exposure to an estrogenic wastewater treatment plant effluent on fathead minnow reproduction

    Wastewater treatment plant (WWTP) effluents are known contributors of chemical mixtures into the environment. Of particular concern are endocrine‐disrupting compounds, such as estrogens, that can affect hypothalamic‐pituitary‐gonadal axis function in exposed organisms. The present study examined reproductive effects in fathead minnows exposed for 21 d to a historically estrogenic WWTP ...

    Leading instrumentation company HACH LANGE is helping a number of key customers save valuable time and costs with its new IL550 TOC-TN analyser. TOC analysis is vitally important in applications ranging from power generation, wastewater, drinking water, surface water and ultrapure water, to agricultural soils, contaminated land and food. HACH LANGE analysers therefore offer a range of options ...


  • The Practical Application of Fine Time Increment, Diurnal, Nitrate Analyses Using Portable In Situ UV Spectrometers in an Effluent Dominated Urban Stream

     ABSTRACT Many wastewater facilities use a nitrifying biological process to eliminate or reduce ammonia concentrations which are toxic to fauna in their receiving water. One byproduct of this process is nitrate. Nitrate is generally non-toxic to fauna in receiving streams at levels produced by a nitrification process. However, chronic exposures of 10mg/L NO3-N, or greater, may produce ...

  • Situation analysis of China’s wastewater discharge

    Great progress has been made in reducing China’s water pollution after decades of efforts. From the perspective of wastewater discharge, the situation of wastewater discharge since 1985 is analysed in this study, with importance attached to industrial wastewater, including wastewater from township enterprises, and to municipal domestic wastewater. In general, the total wastewater discharge in ...

  • Sustainable wastewater treatment chemicals in a dairy

    Problem/Definition Atana Ltd has been tasked in reducing sludge generation produced at the sites effluent plant by introducing a new chemical regime. This would bring considerable savings on their daily running costs; reduce the need for hazardous substances and prevent any corrosive issues through the removal of inorganic chemicals. The plant also has consent issues with FOG and ...

  • Reuse of Wastewater: Johnson & Johnson Medical

     Johnson & Johnson Medical's Sydney plant is recycling water previously discharged from its water purification system. The project demonstrates that common sense 'low-technology' options for recycling industrial process water can ease pressure on both water supply and sewerage systems, and save money at the same time. Background Johnson & Johnson Medical (J&J) ...


  • Efficient Wastewater cleaning for Insulin Production

    Insulin production using biotechnology is now a standard procedure, but it leads to a high level of contaminated wastewater due to tensides which are difficult to break down. A solution provided by EnviroChemie shows how production wastewater output with varying levels of contamination and toxicity can be cleaned efficiently. It combines aerobic and anaerobic steps as well as a low-temperature ...

  • Radionuclides in wastewater treatment plants: monitoring of Sicilian plants

    Three Sicilian wastewater treatment plants were monitored to assess the occurrence and the behaviour of radionuclides. Two sampling campaigns (screening and long-term) were carried out during which liquid and solid samples have been analysed. It was found that 131I mostly occurred in the samples analysed during the screening campaign (43% of the analysed samples contained 131I). ...

  • Elimination of pharmaceuticals from the wastewater of a pharmaceutical plant

    Roche AG had commissioned the company EnviroChemie to develop a new procedure for a new production facility in Mexico, which prevents the undesired release of ecotoxicologi-cally contaminating drugs into the environment and eliminates pharmaceuticals in the wastewater directly at the point of origin, even before the\ enter the general sewage treatment plant. In the first step, the three different ...

  • Improved Wastewater Management for Electroplating: Premier Plating Company

     A custom-designed waste water management system is saving Premier Plating Company $14,400 a year on the cost of treatment and disposal of waste produced by the electroplating process. The company has also reduced water consumption at its plants by a massive 2.2 million litres per year. The system cost only $15,000, so the company’s investment has been paid back in less than a year. The ...


  • Biogas production and potential from U.S. Wastewater Treatment

    How many wastewater treatment plants (WWTPs) have anaerobic digestion? How many are utilizing the biogas? What percentage of these facilities are feeding additional substrates into their digesters? How is the biogas being used — is it flared, used to drive process machinery, heat the digester, or injected into a natural gas pipeline? These are some of the questions asked of the ...

  • Factors affecting the performance and risks to human health of on-site wastewater treatment systems

    Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...
