  • Mastering The Application Of UV Advanced Oxidation Using Chlorine In California (Article)

    Installed at the Albert Robles Center (ARC) in California is the TrojanUVPhox™. Arranged in two parallel trains, the UV AOP system was designed to operate with sodium hypochlorite being injected into the treatment stream instead of more traditional hydrogen peroxide (H2O2). This is commonly referred to as a UV/chlorine or UV/Cl2 approach to UV AOP.

  • Warm Weather Water Treatment: Optimizing Coagulation With Standby Advanced Oxidation

    Seasonal variations and peak events can impact the water quality in ways difficult to anticipate, requiring tools and monitoring methods to optimize drinking water treatment at a moment’s notice.

  • COVID-19 Requires Management Of Building Water Systems Now

    Controlling the spread of COVID-19 requires the collective effort of physical distancing. While this is imperative to save lives from the novel disease, many hotels, resorts, offices, and other buildings are now partially or entirely shut down. As a result, the water systems in these buildings are experiencing low to no flow, loss of disinfectant residual, tepid water temperatures, and other hazardous conditions that can increase Legionella amplification, which can cause Legionnaires disease.

  • Common UV Lamps For Chemical-Free Disinfection

    When it comes to water and wastewater treatment systems, operational and performance variation will come from different components, including what treatment processes are deployed, whether chemicals are utilized, or how much power the treatment processes require. With many treatment systems, there is much consideration given to a particular central component akin to the heart and soul of the process. In the case of a UV system, the ultraviolet (UV) lamps are this component.

  • Xylem Helps South Carolina Utility Eliminate Taste And Odor Issues In Drinking Water

    Advanced oxidation treatment system and water treatment plant upgrade save money.

  • UV Treatment System Fills The Bill For Water Reuse

    Small city selects full-featured and low maintenance UV treatment for its water reuse system that easily complies with demanding California Title 22 Regulations.

  • Cost Benefits Of Process Water Disinfection Via UV Light Sterilizer Technology

    For the sake of the productivity and quality of products, as well as the proper upkeep of process equipment, treating process water prior to use is very beneficial, if not vital. One step in treating process water is often disinfection. While there are several chemical options for disinfection, ultraviolet technology can provide several key cost benefits for onsite treatment systems.

  • 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.

  • Novel Oxidant Lowers Natural Organic Matter Without Creating Disinfection Byproducts

    With twice the oxidation potential as that of chlorine, this mineral oxychloride solution can easily break down carbon bonds and simultaneously lowers organic carbon, meets microbial reduction goals, and complies with the regulatory limits on disinfection byproducts. Disinfection by chlorine can be problematic, as chlorine can react with naturally occurring organic compounds resulting in byproducts that have never existed in nature.

DISINFECTION SOLUTIONS

  • ETS-UV™ For Drinking Water

    Drinking water facilities are under pressure to do more with less. Public safety and water quality cannot be compromised so it's important to incorporate solutions that are proven to perform. A number of ETS-UV™ disinfection systems have been validated by an independent third party for drinking water in accordance with the US EPA Design Guidance Manual and NSF/ANSI Standard 61.

  • Get Rapid & Reliable Settling with the CoMag® System’s New Package Plants

    The CoMag® System settles floc up to 30 times faster than conventional flocculation treatments, enabling plants to increase capacity and clarifier performance.  It helps meet tighter regulations within existing tankage and smaller treatment volumes than alternative technologies, allowing facilities to reduce plant investment costs for upgrades. 

  • Ultraviolet Disinfection ETS-UV™ Systems

    Ultraviolet (UV) irradiation is used for multifunctional purposes.  UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium.  UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC).  UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC's), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.

  • TrojanUVSwift™ECT — Advanced Oxidation System

    The TrojanUVSwift™ECT is a hydraulically optimized, polychromatic lamp-based UV reactor for use in the treatment of environmental contaminants. It is suitable for removing contaminants from large flow rates within a compact footprint.

  • Model 4200-EC Gas Vacuum Feeder Controller

    The JCS Industries Model 4200EC Gas Vacuum Chemical Feeder mixes and feeds gaseous chemicals commonly used for water and wastewater disinfection accurately, reliably and safely. The system is comprised of a vacuum injector to safely introduce the gas into the feed-water stream, a reversing servo motor coupled with a V-notch valve to regulate the chemical flow rate, and a control module for complete electronic control and communications.
