Drinking Water Filtration Resources

  1. Evaluation Of Ceraflow-50 As A Filtration Media For Hexavalent Chromium Treatment 6/1/2018

    Pilot testing was conducted to evaluate the relative performance of 4 filter media, including Ceraflow-50, as part of a reduction coagulation filtration (RCF) treatment process for the removal of hexavalent chromium (Cr(VI)) from groundwater. This evaluation was conducted at multiple well sites for a water utility in California.

  2. Evaluation Of Ceralite-A As An Alternative To Anthracite Filter Media 5/25/2018

    The Golden Heart WTP located in Fairbanks Alaska is a lime softened, ground water treatment plant with five filter basins, with a combined surface area of 1495 ft2 . Typical filter loading rates are in the 2.3 –to 3.1 gpm/ft2

  3. Santa Barbara, Curaçao Desalination Plant: Six Years Of Operation Of LG Chem Thin Film Nanocomposite (TFN) SWRO Membrane 5/14/2018

    The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.

  4. Addressing Fouling Challenges In Water Treatment With RO Membrane 4/18/2018

    Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

  5. Exploring RO's Inner Net 3/14/2018

    A deep dive into reverse osmosis (RO) elements reveals the importance of feed channel spacers for optimal membrane filtration system performance.

  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. How Aurora's Potable Reuse Project Charts The Future 10/3/2017

    A water recycling project in Colorado combines natural processes and cutting-edge technology to ensure drought security for its residents.

  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. Process Water: Building A Better System 8/25/2017

    With factors such as scarcity, aging infrastructure, and water quality driving the price of municipal water higher, businesses are increasingly considering other means of securing supply. This article examines the trend toward alternatively procured process water and its impact on municipal and commercial interests.
