Drinking Water Treatment Case Studies and White Papers

  1. High Recovery Reverse Osmosis Water Treatment For Industrial, Agricultural, And Municipal Applications
    8/13/2014

    Industry accounts for nearly 60 percent of fresh water withdrawals in the developed world and agriculture consumes 70 percent of fresh water supplies globally, according to UNESCO.

  2. Versatility Of Thermal Mass Flow Meters
    3/10/2014

    There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

  3. Dissolved Air Flotation System Reduces Costs, Improves Process
    3/1/2015

    With the town of Johnstown, CO's, water treatment plant began operating its circular clarifier systems at maximum capacity to meet summer peak demand rates, consultants recommeded increasing plant capacity and using dissolved air flotation technology for their clarification process.

  4. Do We Have To Sacrifice Performance To Be Green?
    11/25/2013

    The global use of membranes is widespread in municipal, industrial, and wastewater applications with reverse osmosis (RO) proving to be a highly effective and reliable method of advanced water treatment.  Reuse applications have been particularly challenging for water treatment chemical companies as these highly variable feedwaters can contain any imaginable constituent, resulting in a wide array of site specific foulants. By Karen Lindsey, V.P. Operations, Avista Technologies, Inc.

  5. Dissolved Air Flotation Pretreatment Washes Away Waco’s Foul T&O Problem
    4/18/2013

    During the hot and dusty summers just a few years ago, many thirsty residents of Waco, TX, were reluctant to slake their thirst with the city’s water.

  6. Monitoring Chlorine Residuals For RO Membranes - ORP Versus Chlorine Analyzers
    7/14/2015

    In processes where disinfection is required chlorine is the most common and economic disinfectant followed by sodium hypochlorite (liquid bleach).  It is important to disinfect the RO feedwater to avoid fouling of the membranes which results in poor performance and frequent cleaning.

  7. Case Study: High Chemical & Blowdown Rates
    7/14/2010

    The client used soft water make up on their large boiler system and was interested in reducing their operational water costs.

  8. Precision Air/Gas Flow Measurement Helps Turn Landfills Into Green Electric Power Generators
    1/12/2016

    A leading supplier of landfill gas extraction and recovery systems located in the Midwest region of the US relies on flow meters from Fluid Components International (FCI) for gas flow measurements in landfills. The company has developed hundreds of landfill gas system flares and extraction system skids that are in operation worldwide, which all require accurate gas flow measurement.

  9. Ozone To Enhance Removal Of Iron And Manganese And Reduction Of THM
    4/27/2017

    The U.S. EPA's promulgation of the Stage 2 Disinfection By-Products Rule required  the Public Works Department of Danvers, MA, to establish a Two-Phase upgrade of the plant’s treatment process in order to comply.

  10. Data Validation Of Continuous Analyzers
    10/11/2013

    Continuous analyzers are routinely employed to monitor water and steam cycles in industries such as power generation, municipal water and waste water, pharmaceutical, and microelectronics.  By Randy C. Turner, Technical Director, Swan Analytical USA
