Drinking Water Treatment Case Studies and White Papers

  1. Pre-Filtration Is Essential To Protect Your Membranes
    12/15/2016

    Any Reverse Osmosis System is only as good as the Pre-filtration System protecting it.  Pre-filtration is no place to scrimp when it comes to sizing, quality, efficiency and performance. 

  2. On-Site Disinfection Generation Enables City To Provide High Quality Water For Industrial Food Processing Customers
    7/13/2018

    The city of Buhl, Idaho, obtains all of its drinking water from groundwater sources through multiple wells. Prior to 2009, the city did not treat the groundwater but only added chlorine in the form of bulk 12.5% sodium hypochlorite to provide a disinfectant residual. A combination of factors including: changes in EPA and state DEQ regulatory requirements, growth of the residential population and growth of the industrial food processing customers forced the City to build a new water treatment plant to provide filtration to address the naturally occurring arsenic present in the groundwater.

  3. Instrument Resiliency For Tough Times
    7/17/2018

    Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.

  4. Engineered Solution For Bromate Production During Ozonation
    5/24/2017

    The design of a utility’s ozone disinfection system often includes a method to minimize the production of regulated oxidation by-products that may form when ozone contacts the water. In regions where water contains a significant concentration of bromide ion (Br¯ ), ozone disinfection systems often minimize bromate (BrO3¯ ) formation by modifying the water chemistry through the addition of chloramines, acid, or other chemical additives.

  5. Instrumental Solutions For Better Process And Data Management

    Generating accurate data is essential for maintaining water treatment plant (WTP) process efficiency and regulatory compliance. Here are multiple considerations for automating critical instrument monitoring and management activities that can help generate reliable data as a means of supporting timely decision-making, accurate compliance, and maximum confidence in WTP performance.

  6. Ozone Resolves Hydrogen Sulfide And Color Issues In Well Water
    9/1/2018

    A potable water plant in Eastern Angelina County, Texas,  serves over 2,000 rural customers.

  7. Closed Circuit Desalination Technology Provides Steel Manufacturer ROI In Less Than 60 Days
    8/5/2014

    This leading rod and wire mill requires water for cooling steel and tools in its manufacturing process. Water used for cooling becomes contaminated with metals and lubricants and was therefore being disposed of as waste.

  8. In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility
    6/16/2016

    To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.

  9. Desalinated Water Supply Helps Plant Meet Strict Environmental Regulations
    4/23/2018

    STX Heavy Industries, a Korean EPC, recently implemented a flue-gas desulfurization (FGD) system at a coal-fired power plant in Chile in order to comply with the country's strict environmental regulations. The FGD process requires large amounts of high-quality water. STX.

  10. Six Top Factors To Consider When Selecting A Flow Meter
    7/13/2018

    Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.
