  • A Calgary Wastewater Treatment Plant Finds Real-Time Information on Effluent Quality Critical to Achieving Consistent Performance in Biological Nutrient Removal

    In 1994, the Bonnybrook Wastewater Treatment Plant in Calgary, Alta., completed the first phase of an upgrade to biological nutrient removal (BNR) after several years of testing. Bonnybrook was not the first treatment plant to upgrade bioreactors for nutrient removal: Other communities had struggled with the technology. Bonnybrook operators determined that real-time information on final effluent ...

  • Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements

    Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...

  • Portable IR analyzers: the ideal measurement solution for biofuels blend quality and wastewater testing

    Two challenges facing the biofuels industry involve compliance with blend quality standards and wastewater regulations. According to a study done by the National Renewable Energy Laboratory, 1 the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Integrated Wastewater Management

    ' Appropriate wastewater management, within an overall water resources management program, is essential to responsible use of the environment and to affordable provision of services. Such management programs are best developed at a river basin or sub-catchment level. An approach is outlined for developing a wastewater strategy and an implementation plan for a river basin.' Integrated ...


  • Wastewater Treatment Municipality Of Saint-Claude

    In Quebec, the municipalities must make sure that their rejections of sewerachieve the goals applied to the receiving medium. The Rotating BiologicalReactor (RBR), developed by the biological processes division of H2OInnovation, showed its effectiveness during more than one year testingproject, which contribute to the obtaining of the Standard Technology (CF-1) certification allowed by the Quebec ...
