  3. Flow Data Red Flags: When To Act
    12/20/2017

    Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

  4. Indiana American Water Eliminates Gaseous Chlorine At Hidden Lake WTP In Warsaw, Indiana
    7/20/2018

    In 2000, Indiana American Water, a subsidiary of American Water Company, purchased the Warsaw Indiana system which serves a population of over 16,000. Indiana American then completed a Comprehensive Planning Study that included a number of upgrades and improvements to enhance the reliability, safety and water quality of the system.

  5. Australian City Installs Microclor On‐Site Sodium Hypochlorite Generation System
    7/24/2018

    Bathurst is the home of the Bathurst 1000 Race, the largest NASCAR-style “touring car” race in Australia. On race day, tens of thousands of additional visitors tax the capacity of the Bathurst 5 million-gallon-per- day wastewater treatment plant. The diligence and capability of the treatment staff allows the plant to meet the challenge every year. 

  6. Improving Wastewater Treatment With Air Flow Instrumentation
    12/7/2017

    In wastewater treatment plants, a variety of processes are employed to eliminate organic pollutants from water to ensure its safety and release for future uses. One of the most common processes is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins.

  7. Why Won’t Cellular ATP Levels Decrease After UV Treatment?
    8/7/2017

    UV treatment has only recently become widely adopted in the water and wastewater treatment industries but the benefits of sun exposure for water purification have been acknowledged for thousands of years. 

  8. How To Size Commercial Filtration Systems For Iron & Manganese Removal
    4/17/2017

    Iron and manganese removal treatment systems use oxidation to convert the dissolved forms of the metals to a solid form, followed by a filtration process.

  9. Think You Know ORP? Get 5 pH/ORP Measurement Tips
    6/29/2017

    Water and wastewater treatment professionals are constantly looking for as much information as possible about the quality of their water. If knowledge is power, then understanding the properties of their water is key to running an effective and efficient facility.

  10. Sensor Technology For Control Of Activated Sludge Aeration
    7/19/2013

    Design routines and operation strategies for activated sludge aeration systems have traditionally been based on manual control. By Robert Smith, P.E., BCEE, Ph.D., YSI
