  • Tips On Controlling Dissolved Oxygen in a Wastewater Treatment Plant

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the nonsettleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy. This paper reviews the most common stages for measuring and controlling dissolved oxygen in a wastewater treatment plant.

  • HACH BioTector 3500c Analyzer For TOC, TC, TIC and VOC Analysis

    In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.

  • TOC Measurement in the Chemical Industry

    The most commonly used compound in the chemical industry is water – not only as a solvent in processing, but also as an energy carrier in the cooling or heating cycle. As vast amounts of water are needed, chemical industries are often located close to large bodies of flowing water. Water used as processing or cooling water is cleaned and subsequently led back to the river or stream. For environmental protection, these waters are subject to specific control and monitoring measures. As the total organic carbon (TOC) non-specifically detects all organic compounds, this parameter has proven to be invaluable here. This booklet introduces a variety of industry-specific applications, and how Shimadzu can provide TOC analyzers to meet specific chemical application needs.
