• Best Practices For PFAS Removal In Gravity Filters

  PFAS is a growing problem for municipal water utilities. The contaminant continues to show up in more water sources and regulations are a moving target that will likely involve more compounds and lower acceptable limits. As a result, crafting a long-term strategy to address PFAS can be problematic. However, those utilities using conventional gravity filters with anthracite as the filtering media have an opportunity to continue organic removal while adding PFAS removal with a simple conversion.

• How To Save Time, Save Money With Pilot-Plant Testing

  When developing water or wastewater treatment processes for entirely new applications or modifying existing processes to accommodate changing water characteristics or regulatory discharge requirements, understanding capital investment, operating cost, and long-term performance is critical. Here are several ways to view pilot-plant or lab-scale testing as viable approaches to better outcomes with lower risks.

• AFC Semper RPM®’S “Lift And Shift” Ability Shines In Forsyth County, Georgia

  Since the Forsyth County, Georgia, Department of Water and Sewer deployed the AMERICAN Flow Control SEMPER® Remote Pressure Monitor (RPM) more than a year ago, it has seen numerous advantages. But the AFC SEMPER’s ability to move from one system asset to another, “Lift and Shift,” is among the greatest. Introduced in February 2020 in partnership with Trimble Water, the AFC SEMPER RPM is a wireless, battery-powered pressure recorder that provides utilities with the data needed to monitor water pressure throughout their systems, help identify transients and reduce non-revenue water.

• Advanced Treatment Systems Tackle Taste And Odor Issues

  There is no question that unpleasant taste and/or odor in drinking water can create negative water quality perception challenges for water utilities. Though taste and odor are not health concerns, consumers still are likely to notice and voice their concerns.

• ABB Technology Further Strengthens Singapore’s Water Security

  The United Nation’s (UN) World Water Development Report recently stated that nearly 6 billion people will suffer from clean water scarcity by 2050. Singapore is using desalination as part of the solution to their water supply issue in order to provide enough clean drinking water for its ever-growing population of 5.5 million.

• Overcoming Space Constraints For An Accurate Flow Measurement

  Accurate and reliable flow measurement is critical to many water treatment and distribution applications. However, this can be a dicey proposition because most metering solutions require a set amount of straight pipe runs, before and after the device, to ensure accuracy. To address these and other related issues, an innovative solution has emerged.

• A Strong Track Record Of Innovative Iron And Manganese Treatment

  For many utilities, properly treating the iron and manganese in source water is critical to maintaining good customer relationships. When iron and manganese are present, they are often accompanied by arsenic contamination. Here are several examples of utilities that successfully installed treatment systems to address the trio of contaminants.

• A Better Approach To Iron And Manganese Removal

  The aesthetic impact of iron and manganese on finished water — altering its color, odor, and/or taste — is the top driver of municipal utility customer complaints. While there are well-established treatment processes for these contaminants, innovative medias can provide many benefits that traditional technologies lack. This includes lower capital and operating costs, as well as a smaller footprint in some cases.
