WATER INDUSTRY FEATURES, INSIGHTS, AND ANALYSIS

DRINKING WATER PRODUCTS

Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

Veolia has developed ShaleFlow™, a cost-effective transportable solution for reuse of produced water and flowback water from hydraulic fracturing operations. This compact, modular system utilizes proven technologies designed to enable reuse with the flexibility to be moved as the field is developed.

VIEWS ON THE LATEST REGS

  • With the U.S. EPA's PFAS rules now in place, utilities are finding themselves with a growing number of questions regarding how to treat these chemicals, the potential costs, and much more. For answers, Water Online's chief editor, Kevin Westerling, hosted an Ask Me Anything session featuring Ken Sansone, Senior Partner at SL Environmental Law Group; Kyle Thompson, National PFAS Lead at Carollo Engineers; and Lauren Weinrich, Principal Scientist at American Water.
  • A Q&A to explain and resolve issues confronting water suppliers as they endeavor to comply with the monitoring requirements of federal PFAS regulations.

  • Assessing what lies ahead in the 10-year race to go lead-free, otherwise known as the Lead and Copper Rule Improvements (LCRI).
  • Many water systems are still tackling the challenge of identifying and compliantly managing galvanized and galvanized-requiring-replacement (GRR) service lines.

  • In the most recent edition of Water Innovations, there is not a single article focused on PFAS. That wouldn't be exceptional if not for the fact that discussion around per- and polyfluoroalkyl substances has so thoroughly dominated the water space lately. And yet, I penned this as an intro to the edition — just "a tiny bit of PFAS" content — because a small portion of PFAS is of the utmost importance in terms of treatment, policy, and cost.

  • Ozone is a vital pre-treatment for PFAS mitigation. It oxidizes precursors and co-contaminants, significantly extending the service life of downstream GAC and membrane systems.

  • UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

  • Analyze projected image distortion in cinemas, detailing keystone, anamorphic, and curved-screen effects, with calculations and tolerance guidelines to ensure visually pleasing image quality.

  • Per- and polyfluoroalkyl substances (PFAS) are hazardous substances that harm ecosystems and can have severe effects on human health, compounded by their persistent nature and environmental accumulation.
