Wastewater Membranes White Papers & Case Studies

  1. 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.

  2. MBR Helps Ohio WWTP Expand Its Facility Within Its Existing Footprint
    4/1/2014

    The Carrollton Wastewater Treatment Plant located in eastern Ohio, was upgraded from conventional activated sludge technology.

  3. Oldest Town In West Virginia Adopts Modern Wastewater Treatment System
    3/6/2014

    Along the banks of the Potomac River and nested in the lower Shenandoah Valley, sits the quaint and historical Shepherdstown, the oldest town in West Virginia with nearly 1,200 residents and home to Shepherd University which serves about 4,000 students. The town attracts visitors year-round who come to take in the shops and bistros along German Street and visit the town’s many historical landmarks including the Mecklenburg Tobacco Warehouse. This 1920’s landmark housed the town’s waterworks that supplied water to Shepherdstown residents until the mid ‘70s.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.
