Drinking Water Filtration Case Studies and White Papers

  1. Produce Potable And Pharmaceutical Grade Water From Problematic Brackish Water
    7/15/2014

    A pharmaceutical manufacturing plant located in Sedom, Israel faced challenging environmental conditions including low humidity, temperatures exceeding 105 degrees Fahrenheit and limited water supplies.

  2. Reducing Effluent Waste While Using Less Energy With CCD
    7/15/2014

    A pesticide manufacturing plant in Gujarat, India produces up to 6,000 metric tons per year of various pesticides for agricultural use.

  3. Hydrogen Sulfide Removal From Water Using AquaSorb® CX-MCA
    2/19/2014

    The “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.

  4. Using Membrane Contactor Technology To Extend Resin Bed Life
    2/13/2014

    In today’s economic environment when profits are reduced due to rising costs, it is necessary to find ways to save time and money.

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

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

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.>
