Drinking Water Treatment Case Studies and White Papers

  1. Full-Scale Installation Report For Z-88® Radium Removal – City Of San Angelo, TX
    8/9/2018

    The City of San Angelo, TX selected WRT’s Z-88® Radium Removal treatment system for reducing high levels of radium in their wells.  The city’s Phase I treatment plan was fulfilled in 2014 with the installation of the first Z-88® Radium Removal treatment system. This large treatment facility has been reducing the levels of radium below the Maximum Contaminant Level (MCL) since it’s inception.

  2. AMERICAN Pipe And Valves Ensure Georgia Project Flows With Ease
    6/29/2016

    The estimated $30-million West Side Loop 48-inch Replacement Project is one of three capital projects being conducted by the Cobb County-Marietta Water Authority to provide additional water to western Cobb County and Paulding County in Georgia. For the project, a 48-year-old, 36-inch pre-stressed concrete cylinder pipe (PCCP) that recently failed is being replaced with 48-inch ductile iron pipe.

  3. 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.

  4. Meet (Or Beat) EPA Nitrate MCLs With An AdEdge Packaged Nitrate Removal System
    8/22/2012

    When a food processing plant in Lancaster County, PA was forced to supply bottled water to its employees due to high nitrate levels in its raw water, they had no choice but to investigate a nitrate removal solution. In this case study you’ll learn how the plant avoided EPA violations by reducing nitrate contamination levels to below 8 mg/L and simplified continuous monitoring by implementing a new packaged nitrate removal system from AdEdge.

  5. An Energy System For Power Generation Relies On Quality Monitoring Instruments From Siemens
    11/23/2015

    A U.S. company develops energy technologies that are environmentally sustainable and provides their customers with the ability to use their energy sources in a more practical and cost-effective manner.

  6. TotalCare Condition Audit Results In Energy Savings Of 80% And Improved Controls
    5/1/2017

    Xylem TotalCare Condition Audit, an inspection and recommendation program that helps plant operators find ways to lower maintenance costs by identifying inefficiencies in the operation of water and wastewater equipment, was elected to audit the American Canyon Wastewater Treatment Plant (WWTP) in California.

  7. 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.

  8. Replacement Of Gas Chlorination System: City Takes Advantage Of Special NaOCl Dosing Unit
    4/5/2012

    Operations management for a municipal direct water filtration plant reports achievement of a reliable and cost-effective change in chlorination systems that has continued to provide for effective disinfection, while better meeting safety and efficiency criteria. By Cliff Lebowitz

  9. An Alternative Mathematical Model For Oxygen Transfer Evaluation In Clean Water
    6/20/2014

    Energy consumption from aeration system is a biggest part of the total energy cost in wastewater treatment plant and account for as much as 60% of the energy consumption for the activated sludge process. Therefore, it is very important to know how effective the aeration system and significant attention has been paid to development and upgrade of standard method for quantifying oxygen transfer efficiency of the aeration system. By Yanjun (John) He, PE, BCEE, Kruger Inc.

  10. Direct Filtration Of Spring Water
    10/23/2012

    The Franklin Water Treatment Plant, near the Utah/Idaho state border, serves approximately 600 residents. Traditionally, water was drawn from springs and chlorinated.
