CONTAMINANT REMOVAL RESOURCES

  • Despite electrocoagulation's demonstrated effectiveness, developing a reliable, low maintenance reactor with sufficient water processing volume has proven to be a significant engineering challenge.

  • As utilities prepare for the pending 4-ppt PFAS drinking water MCL, many are discovering that legacy lead/lag designs—workhorses for decades when treating contaminants in the ppm and ppb range—simply are not optimized for the parts per trillion-level (ppt) precision PFAS demands.

  • Ion exchange (IX) is a tried-and-true method of removing metals and other inorganic compounds from water. Arsenic, cadmium, chromium, copper, lead, nickel, selenium, radionuclides, and zinc are just a few examples of the compounds that our ion exchange systems have removed from water.

  • 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.

  • Ozone and UV-AOP each offer powerful contaminant removal for drinking water, wastewater, and reuse applications. Their unique strengths—and potential synergy—help utilities meet diverse treatment goals efficiently.

  • In two bench-scale tests, a new technology effectively removed up to 99% of chlorides and 97% of total dissolved solids in a single pass. This solution offers a commercially viable alternative to traditional treatment methods.

  • Implementing and managing a Legionella control regime can sometimes seem daunting and complex. Invariably, a lot of resources, time, and effort are needed to achieve the required standard and provide assurance to senior management and auditors that controls are effective and those that are not are being managed and rectified appropriately.
  • The most common techniques for disposing of PFAS may no longer be good enough.
  • This article will explore five common misconceptions about GAC and IX technologies for PFAS removal, helping utilities choose effective, site-specific treatment strategies for contaminated drinking water.

  • Drinking water systems across America face a mounting PFAS threat with starkly different capacities to respond. Large urban utilities typically have ample resources to detect and remove these persistent chemicals from water supplies, while small rural systems operate with tight budgets, skeleton crews, and minimal technical support.

CONTAMINANT REMOVAL SOLUTIONS

  • ISOLUX® Arsenic Removal Cartridges

    Applied Cartridge Systems provide a choice of user-friendly cartridges to meet a range of water treatment issues. The NSF 61 certified ISOLUX® cartridges, (also known as ATOMUS® I22), are designed specifically to remove Arsenic from drinking water. Using a proprietary Zirconium adsorption media, ISOLUX® cartridges remove Arsenic III & V simultaneously down to non-detect levels, even in extremely high concentration applications.

  • Lug Style Butterfly Valve: Type 578

    The Type 578 Lug Butterfly Valve has several beneficial design features unique to the Georg Fischer butterfly valve line. The double eccentric operating principle has an off-center disc and shaft that disengages the disk from the seal with only 3 degrees of rotation.

  • Ion Exchange Systems

    Loprest has been providing ion exchange treatment systems for the removal of arsenic, nitrate, perchlorate, hardness, fluoride and other contaminants for many decades. 

     

  • Capital Controls® Series 1041A Automatic Switchover

    The Automatic Switchover system Series 1041 provides safe, reliable switching between two gas (pressure or vacuum) or two liquid (pressure or level) sources assuring an uninterrupted supply of chemical to the application. Automation of all functions (switchover, system initialization, configuration, lamp test, and safety functions) is done with an internal programmable logic controller for operational flexibility, enhanced reliability, and ease of use. If needed, local manual override is conveniently available for operator control to maintain continuous operation.

  • Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
