  • 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.

  • 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.

  • Optical System Sets New Standards in Oxygen Measurements

    Optical Dissolved Oxygen Measurement in Power and Boiler Applications

    Over the past decade a few trends have started to gain pace within the industry, driving a change in instrumentation requirements for operations managers and plant chemists:

    • Maintenance and operations budget cuts have resulted in fewer plant personnel, forcing plant staff to optimize their workload even further
    • As the cost of building new power and boiler systems increase, many operators now look to plant life extensions as a solution to bridge gaps in production capacity at a lower investment premium

    These trends have changed the requirements in these applications. Starting from these trends, this article analyzes the options for oxygen measurements that are precise, reliable, stable, and above all require low to zero maintenance.

  • Reducing Water Consumption in Compressed Air Systems

    Compressed air systems are sometimes called the "4th Utility" due to their presence in almost all industrial processes and facilities. As US water consumption continues to increase, compressed air systems provide an opportunity for energy managers to reduce associated cooling water consumption and costs. In this white paper, we focus on the opportunity to reduce the water consumption of compressed air systems. Understanding the costs and the alternative types of cooling systems is an important first step. This white paper provides background on US water consumption in both the public and industrial sectors; it provides detail on industrial water consumption -- including industrial cooling water -- and its associated costs; it also details six different types of cooling systems available.

  • The Perils of a DIY Distributed Control System

    The debate over the virtues of DCS vs. PLC has been ongoing since these two architectures came into existence 40 years ago. For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. As functionality differences narrow and price points align, the debate over these virtues is getting more intense and the arguments for and against each system are getting more and more murky. This white paper discusses the “Top Ten” issues to consider when evaluating a DCS vs. building your own “DIY” distributed control system using a PLC-based architecture.
