    In Canada and the western United States, long treated water transmission lines are frequently utilized to convey potable water to rural communities. These long transmission lines combined with chlorine for water disinfection can often create the requisite conditions for the formation of undesirable disinfection-byproducts (DBPs). One of the most common DBPs is a family of volatile compounds called Trihalomethanes (THMs) which are regulated in Canada to a level of 100 ppb (part-per-billion) annual average and in the US to a level of 80 ppb.

It’s also why the water purifier market continues to experience extreme growth and is expected to garner $45.3 billion by 2022 as companies in the space look to better cater to consumer demand.

  9. Top Research Institute Turns To On-Site Generation For Drinking Water System
    9/18/2018

    As one of the top 20 American research institutes in the United States, Texas A&M has hundreds of laboratory facilities on its campus where a variety of proven water treatment technologies are used to control the quality of the water used in research.

  10. Water Wholesaler In Dallas Fort-Worth Metro Area Upgrades To New Generation Of On-Site Hypochlorite Generation To Improve Safety And Reliability
    7/12/2018

    The Upper Trinity Regional Water District (UTRWD) is a conservation district created by the State of Texas in 1989 to provide water, wastewater, solid waste and storm water services to numerous towns and cities approximately 50 miles northwest of Dallas. In 2010, the UTRWD installed three 2,000 pound per day (PPD) chlorine equivalent Microclor® OSHG systems. The systems continue to provide UTRWD with a reliable supply of hypochlorite for disinfection in a manner that is less expensive and less risky than gas chlorine or liquid bulk hypochlorite delivered via truck or rail through such a heavily populated area.
