Desalination Resources

81. Overcoming Difficult Conditions, Salty Groundwater And Changes In Feedwater Quality 8/13/2014

    Kibbutz Reim had to convert salty groundwater into a high quality irriga­tion resource in this desert-like region. High recovery was essential to this customer, both because of the limited amount of groundwater available and the challenge of brine disposal from their inland location.

82. 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.

83. Pulp And Paper Manufacturer Significantly Increases Production While Complying With Discharge Limitations 8/5/2014

    A U.S.-based pulp and paper manufacturer required high purity process and boiler feed water. It was using water from a local well and treating it with a 150 gpm conventional RO system operating at 75% recovery, but this was creating 50 gpm of wastewater – over 26 million gallons per year.

84. 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.

85. Eliminate CIP And Cut Wastewater Disposal In Half With CCD 7/31/2014

    A high water recovery rate is essential for this well-known soy protein manufacturer.

86. Reliable Production Of High Quality Permeate For Irrigation 7/26/2014

    Following one of the driest periods on record in California, farmers in the San Joaquin Valley faced restricted water allocations.

87. CCD Technology Succeeds With Well Water Purification 7/15/2014

    The Kittansett Golf Club in Marion, Massachusetts is rated one of America’s 100 Greatest Golf Courses by Golf Digest Magazine.

88. 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.

89. 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.

90. Decrease Membrane Treatment Capital And O&M Costs With Optimum Flux Rates 6/30/2014

    Despite a global effort to standardize units of measure to the metric system, the water treatment industry still follows the U.S. trend in resisting that directive by referring to water volumes in treatment plants as gallons per day (GPD).  While achieving a specified permeate GPD is certainly important in overall membrane plant design, production capacity has absolutely nothing to do with determining optimal methods of treating site-specific feedwaters and offers no indication of potential membrane fouling rates and related maintenance costs. To evaluate these factors, knowledgeable professionals rely on membrane flux rates as the key consideration in achieving optimal system design and operation. By Harold G.
