DRINKING WATER TREATMENT RESOURCES

• 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.
