  • EBS and SENTRY demonstrate real-time monitoring to detect Black Liquor discharge events

    Black liquor is formed as a by-product of the Kraft pulp and paper manufacture process. In In the Kraft process, about half of the wood is dissolved, and together with the spent pulping chemicals, forms a liquid called black liquor. Black liquor spills from the process can subject a downstream wastewater treatment system to periods of upset conditions and could potentially push the total BOD ...

  • The Dawn of a New Era: Real-Time BOD Data Case Study

    In many areas of our life, manual monitoring has been replaced by automatic or online monitoring as and when the instrumentation technology has been developed; however there is one area that has fallen behind the times and has not caught up which is water quality. Many parameters are simply not possible to measure in the field or can only be done by grab sampling. In the last ten years or so we ...

  • Toxicological Evaluation of the Chemical Oxidation Methods for Landfill Stabilization

    Abstract : As the stabilization criteria for landfill sites, only chemical criteria for the leachate discharges from the landfill sites have been used in Japan and many other countries. Recently, chemical oxidation has been developed as a method for the early-stabilization of landfills. However, by-products that are difficult to detect by chemical analysis can be produced by this method. ...
