Wastewater Membranes White Papers & Case Studies

  1. How Can Seasonal Establishments Treat Their Wastewater Economically?
    2/20/2014

    Opened a few months per year, seasonal establishments typically experience important fluctuations in the number of visitors. Energy consumption and operating expenses must continually be analysed and optimized. The implementation of efficient energy management practices and the integration of innovative wastewater treatment solutions that can improve their cost-efficiency ratio have become major sources of savings for this whole industry.

  2. 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.

  3. Clarification System Boosts Capacity, Reduces Maintenance
    2/3/2014

    Spikes in peak demand at the 3.0 MGD Freedom District Water Treatment Plant in Carroll County, MD, exceeded 70 percent of the plant’s capacity, and the existing clarifier made for a lengthy sludge-removal process. After staff installed a dissolved air flotation (DAF) pretreatment system to improve the efficiency of the membrane filters, the now 4.0 MGD facility has reduced maintenance for operators. The system also safeguards against pathogens that can pass through traditional sand/diatomaceous (S/D) filters.

  4. Flat-Sheet Membrane Units Increase WWTP Capacity
    12/18/2013

    Following several years of inadequate performance and intensive cleaning requirements, the owners of the Callao, VA, wastewater treatment plant looked for a solution. The installation of two flexible, flat-sheet membrane units provided an instant capacity increase and a decrease in sludge accumulation, resulting in streamlined plant operations.

  5. 3M Liqui-Cel Membrane Contactors Remove Dissolved Gases From Water In Many Hydrocarbon Recovery And Process Applications
    11/26/2013

    The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. Minimizing the environmental impact, improving operating efficiency, avoiding process issues and protecting system components are just a few of the reasons degassing is necessary in many hydrocarbon recovery and water processes.

  6. 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.

  7. 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.

  8. Membrane Filtration Water Treatment Plant Meets Hotel Complex's Needs
    10/23/2012

    The Little America West Hotel complex located near the town of Granger, Wyoming, used an outdated surface water treatment plant that provided poor quality water during storm events.

  9. Camp Steiner, Utah Case Study
    12/22/2011

    Located at 10,400 feet in the Uintah Mountains of Utah, Camp Steiner is the highest Boy Scout camp in the United States.

  10. Silver Eagle Refinery Case Study
    12/22/2011
    North Salt Lake and West Bountiful are home to several large oil refineries. These large plants have several smoke stacks, open burning flares, and round storage tanks.
