Drinking Water Treatment Insights

  1. Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment
    1/14/2019

    The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

  2. The Role Of IoT And Control Technologies In Water Filtration Systems
    1/10/2019

    With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.

  3. A New Way To Kill Legionella
    1/10/2019

    Advanced oxidation provides an all-in-one solution that supports the complete eradication of Legionella in a water system, while also preventing its regrowth.

  4. Getting Smart About America’s Potable Water Problem
    1/10/2019

    When it comes to fixing pipeline infrastructure, the pressure is on — but is it being measured? Intelligent pipe solutions provide flow and pressure data for improved service and water quality.

  5. PFAS — A National Problem With Personal Costs
    1/10/2019

    Even as the drinking water crisis draws more attention, the true impact of PFAS exposure may be largely underestimated, necessitating louder calls for action.

  6. Restoring Rio de Janeiro’s Forests Could Save $79 Million In Water Treatment Costs
    1/9/2019

    Rio de Janeiro boasts the world's largest water treatment plant, and it's working overtime. The Guandu Water Treatment Station provides 90 percent of the city of Rio's water, and it's increasingly grappling with water quality problems. One challenge is that forest loss and landscape degradation upstream of the city is causing soil erosion, which generates more pollution, and fills reservoirs with sediment instead of water.

  7. Design And Care Of Reverse Osmosis Systems, Part 1: Design
    12/20/2018

    Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.

  8. Trouble In Paradise, And A Plan To Alleviate It
    12/4/2018

    While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.

  9. Turning Down The Power On High Recovery Desalination — A Global Need
    11/30/2018

    Envision a world absent of a water crisis, an end to the threatened health and economic welfare affecting nearly 1.5 billion people due to water scarcity. Clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century and we are only scraping the surface on achieving public awareness. As our global population increases, access to clean water decreases; a metric with diminishing returns.

  10. Akron’s Path Toward An Intelligent Water Network Reduces Chemical Dosing While Improving Water Quality
    11/8/2018

    When water demand declines, water quality and utility budgets can suffer. When the situation arose in Akron, OH, a smart solution emerged.
