  • How To Provide Effective Disinfection With No Hazardous Chemicals
    How To Provide Effective Disinfection With No Hazardous Chemicals

    Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals. Operators must be extensively trained in specialized procedures to ensure their safety and that of the community.

    As water and wastewater treatment plant (WTP/WWTP) processes and control systems become more sophisticated, maximizing operator effectiveness becomes more complex as well. A well-planned alarm and control strategy can make a significant difference between valuable decision-making information and confusing, disjointed, data points. This article highlights key strategies for foreseeing problems in advance, fixing them faster, and having a higher success rate by maximizing operator effectiveness.

  • The Role Of IoT And Control Technologies In Water Filtration Systems

    ​Water and wastewater treatment applications encompass a wide range of processes, technologies, and physical/chemical methods. Among them, filtration and separation technologies are the core of treatment processes, and in many cases, they can be critical process bottlenecks. Engineering firms, engineering procurement and construction contractors, and end users have high expectations regarding a plant's operation, process design, efficiency, and performance.

  • What Are The Hidden Costs Of Water?

    There are a variety of costs that are easy to overlook in water treatment. But as Herman Coello, Products Manager for SIEMENS Process Instrumentation, explains in this Water Online video, accurately measuring your flow and treatment parameters can reduce them all.

  • Boiler Feedwater — Making The Case For Reverse Osmosis

    Boiler feedwater is comprised of two very important, and increasingly expensive resources: steam condensate return and city (or well) makeup water. The condensate is valuable due to low electrical conductance, purity, and high temperature. The makeup water is valuable because it is being overused and under conserved in many parts of the country, making the cost of water rise in almost all parts of the U.S.
