DRINKING WATER DISINFECTION RESOURCES

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

  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.
