Water Membranes White Papers and Case Studies

  1. Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed 11/14/2017

    The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life — from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA Denite technology is treating 450+ MGD in the Bay.

  2. Protecting Water Resources: A Multifaceted Approach 11/7/2017

    As the cost of and demand for potable water increases, engineers, planners, and utilities need reliable, innovative methods for protecting this valuable resource. Cost-effective and environmentally sustainable wastewater collection and treatment systems are vital components in the water cycle and therefore require careful analysis. While there is no single solution for every site or community, traditional ‘big-pipe’ systems are rarely appropriate in sensitive environments; fortunately, today there are more options than ever to consider.

  3. Fluence's MABR For Wastewater Treatment features Passive Aeration And Saves Up To 90% On Energy Costs 10/26/2017

    The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality. Its existing plant was old and did not meet regulation nor industry standards. Fluence, together with its partner SD&C Inc., built an MABR-based wastewater treatment plant from the ground up, utilizing whatever existing pieces of equipment could be used from the old plant.

  4. Latest Trends And Developments In The Global Water Treatment Equipment Market 10/18/2017

    Even though 70 percent of our planet is made up of water bodies, yet the world is facing a dire scarcity of water, a basic necessity of life. More than 97 percent of the water resources available are in the form of saline water in the seas and oceans. Water is always at a high risk of getting contaminated/polluted. With rapid urbanization and demographic growth across the globe, the world has seen a staggering rise in the number of industries.

  5. A Fouling-Free Filter For Produced Water 10/18/2017

    Hydraulic fracturing is a hot-button issue, but no matter where you land you should agree that more efficient produced water filters will go a long way in improving the practice.

  6. Membrane Module Pilot Test In North Dakota 10/11/2017

    Toray UF membrane modules were piloted over a fifteen-week period to help service the growing demand for clean water in southwest North Dakota. The outcome, as part of the Southwest Pipeline Project (SWPP), would be construction of the Oliver-Mercer-North Dunn (OMND) Water Treatment Plant.

  7. Integrated Membrane Facility In The City Of Delaware, Ohio 10/11/2017

    To better comply with the Long Term 2 Enhanced Surface Water Treatment Rule (LT2) the City of Delaware (Ohio) piloted Torayfil hollow-fiber PVDF membrane modules to treat surface water for their 7.2 mgd full-scale facility. After significant review of the data, cost, and other factors, the City and URS selected Toray to utilize in the full scale design. Read the full case study to learn more.

  8. Why RO Plants Need Pretreatment 10/6/2017

    Reverse osmosis (RO) is today among the most commonly used water purification technologies, in both public and private spheres. RO plant manufacturers supply large municipal bodies as well as smaller communities, and RO plants also have a widespread commercial usage — for example, within the food and beverage industry.

  9. How To Know It's Time To Replace Your RO Membrane 9/5/2017

    Reverse osmosis, or RO, is one of the finest technologies to purify water containing high total dissolved solids (TDS) levels of more than 500 ppm. Reverse osmosis plant exporters explain the technology as a separation technology where dissolved and invisible impurities in water are separated with the help of semi-permeable membrane or RO membrane that works under high pressure.

  10. New Membrane Gel Keeps Viruses Out Of Wastewater 7/24/2017

    New research has developed a membrane technology that repels deadly viruses while maintaining permeability. Is it a ‘must have’ for treatment operations?
