  • Top 5 Drinking Water Issues To Be Resolved

    These comments address five major current topics that U.S. EPA has on its agenda: the Lead and Copper Rule (LCR) proposal, perchlorate, per- and polyfluoroalkyl substances (PFAS), Legionella, and distribution systems. The latter two, Legionella and distribution systems, provide the greatest public health risks associated with drinking water and warrant the highest priorities for management, investments, and health and safety improvements.

  • Wastewater Treatment Plant Realizes The Importance Of Using Genuine Replacement Parts In Its UV Disinfection System (Case Study)

    The UV system installed at the Lucas County Water Resource Recovery Facility includes a total of four banks, with 48 UV lamps per, for a total of 192. The facility was experiencing disinfection inefficiencies and, even after repeated inspection and analysis, staff couldn’t figure out why. They started to question if the issues were stemming from the use of non-OEM, non-genuine UV lamps, quartz sleeves, and ballasts.

  • Understanding PFAS’ Impact On Remediation Strategies

    For more than 16.5 million water-utility customers in 33 different states, contamination caused by per-and polyfluoroalkyl substances (PFAS) is a source-water issue that will not go away for a long time. What are the practical options for community water systems currently confronting this challenge? Here is an overview of several treatments and their relative successes against a wide variety of PFAS compounds.

  • All Eyes On Iran

    Iran is facing a water crisis. The World Resources Institute says it’s number 4 on the crisis list after Israel, Lebanon, and Qatar.  Water consumption is increasing, aquifers have been drunk dry, and investment is inadequate.

  • 4 Benefits Of Sodium Zeolite For Drinking Water Treatment

    Use of treatment systems that effectively target and treat toxic and undesirable contaminants is essential to drinking water production. There are typically four stages in a standard drinking water treatment system process, coagulation/flocculation, sedimentation/clarification, filtration, and disinfection. Sodium zeolite is typically utilized in the filtration systems within the filtration stage for optimal treatment performance.

  • 2020 Industry Forecast: Treatment Moves Down The Line

    It’s no secret that safe and readily available water is important for public health, can boost economic growth and help reduce poverty. But factors such as climate change, growing populations, natural disasters, increasing water scarcity, and urbanization continue to challenge water systems around the world. 

  • Preparing To Tackle The Hydra Of LCR Revisions

    As a journalist serving the water industry — but not yet a seasoned technical veteran — I attended a recent Lead In Drinking Water Forum sponsored by AWWA NJ to learn about the challenges of complying with the proposed Lead and Copper Rule Revisions (LCRR). What I heard impressed upon me the technical, administrative, and logistical challenges of delivering safe, lead-free drinking water all the way to user taps. Here are my takeaways.

  • When To Replace Your RO Membrane

    On the surface, it might seem that knowing when to replace the membrane elements in a reverse osmosis (RO) system would be simple. In attempting to keep it simple, many companies will use one or more of the following guidelines for replacing their membrane.

  • Capital Controls® Series 480 Vacuum Gas Feeders

    The Capital Controls® Series 480 all-vacuum gas feeder is designed for direct mounting to a 150 pound gas cylinder or ton container. It is a basic alternative for those applications requiring a chlorine feed rate of 250 PPD (5 kg/h) or less. The gas feed rate is controlled under sonic flow conditions eliminating the need for an auxiliary differential pressure regulators.

  • Disinfection: MCL

    The MCL monochloramine system is intended for the determination of monochloramine in fresh water

  • Pressure Filters

    WesTech granular activated carbon (GAC) contactors are an effective means for removal of low-molecular-weight contaminants from aqueous solutions.

  • SIPART PS100

    Positioners are essential to the smooth and reliable operation of your process. They play a vital role in ensuring the best possible performance throughout your plant. A great example is our new electropneumatic positioner, the SIPART PS100. Its ease and speed of initialization make it a winner for valve manufacturers, the chemical industry, the energy sector, and many other fields. Special benefits of the SIPART PS100 include robust construction and ease of operation.

  • OPTIFLUX 4300 Electromagnetic Flowmeter

    The OPTIFLUX 4300 is an electromagnetic flowmeter (EMF) for advanced process applications with aggressive liquids or abrasive media. The high-end flowmeter is particularly suitable for critical applications requiring high accuracy and many diagnostic functions. It enables reliable measurement even under very harsh process conditions with temperatures up to +180°C / +356°F, low conductivities (≥1 µS/cm), high solid contents (up to 70%) and high pressures (up to 1500 bar / 21751 psi). For custody transfer applications, the OPTIFLUX 4300 has a wide range of certifications including OIML R49 and R117 or MI-001 and MI-005. It can also be used for flow measurement in district heating networks requiring MI-004 approval.
