Drinking Water Filtration Case Studies and White Papers

  1. Solve High Alkalinity With Membrane Contactors
    2/10/2014

    A membrane degassing system can solve high bicarbonate alkalinity that negatively affects anion bed life. 

  2. Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)
    12/30/2013

    Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

  3. Ion Exchange Resins And Activated Carbons For Better-Tasting Water
    12/18/2013

    For many, access to good-tasting tap water is limited, and buying bottled water can be expensive. Simple pour-through jug filters offer a low-cost and effective alternative. Activated carbons, in conjunction with ion exchange products, produce drinking water that is absent of all industrial pesticides and contaminants.

  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.

  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. Stinkin' Drinkin' Water No More: Oxidation/Filtration Removes Hydrogen Sulfide
    4/15/2013

    AdEdge Water Technologies, LLC was contacted by Aqua Utilities Florida to provide a hydrogen sulfide removal system for the Lake Josephine community, located in Highlands County, FL. The treatment goal for the system was to reduce the levels of hydrogen sulfide to the nondetectable odor threshold of <0.05 mg/l.

  7. MEMCOR® Continuous Microfiltration System Maximizes Water Resources For The City Of Scottsdale, Arizona
    3/26/2013

    The desert community of Scottsdale, Arizona had no natural surface water sources and a decreasing groundwater supply. Scottsdale had historically treated and disposed of its wastewater.

  8. Groundwater Remediation - Stockton, California (Case Study)
    12/12/2012

    In the early 1990’s, the volatile organic compounds (VOCs) tetrachloroethylene (PCE), and trichloroethylene (TCE) were discovered in the vicinity of several city water supply wells near the city of Stockton, California.

  9. 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.

  10. 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.
