Drinking Water Filtration Resources

  1. Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment 1/14/2019

    The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

  2. The Role Of IoT And Control Technologies In Water Filtration Systems 1/10/2019

    With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.

  3. Design And Care Of Reverse Osmosis Systems, Part 1: Design 12/20/2018

    Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.

  4. Trouble In Paradise, And A Plan To Alleviate It 12/4/2018

    While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.

  5. California Dreamin'? Pilot Study Makes Treating Arsenic, Manganese And Iron A Reality (Loprest) 10/12/2018

    A pilot study was conducted for arsenic, manganese, and iron treatment system at a well site. The onsite pilot test demonstrated the performance of the Loprest Water Treatment Company treatment process.

  6. Pilot Test For Manganese Removal Using Manganese Greensand 10/11/2018

    Filtration rates, run times, backwash procedures, chemical dosage rates, etc. are all established by theoretical calculations and history. Therefore, Loprest’s goal in this pilot study was to conduct uninterrupted operation per bid testing procedures and document the results.

  7. Is Coagulation Followed By Filtration Viable To Remove Arsenic When Raw Water Arsenic Levels Are High? (Loprest) 10/9/2018

    A pilot study hoped to demonstrate "proof of concept" if coagulation followed by filtration was a viable technology to remove arsenic when raw water arsenic levels are high.

  8. Removing Iron, Arsenic, And Manganese To Meet California Regulations 10/9/2018

    A pilot study was conducted in Sacramento to provide manufacturers an opportunity to demonstrate the effectiveness of water treatment products that employ oxidation and filtration to remove iron, manganese, and arsenic to levels.

  9. Philippines Potable Water System Improvement Project Uses Filter Underdrain Blocks To Improve Backwash Efficiency 10/9/2018

    Founded in 1997, the Manila Water Company (MWC) serves the potable water needs of more than five million residents of the Philippines capital and cities to the east. The company serves as the private partner in a public-private partnership with the Philippines government in operating the Metropolitan Waterworks and Sewerage System for Metro Manila’s East Zone.

  10. A Pilot Study Involving Three Different Treatment Media (Loprest) 10/8/2018

    As part of a feasibility study for arsenic treatment at an elementary school in California, a pilot study was conducted to test the performance of three different treatment media: (1) greensand and anthracite, (2) standard sand and anthracite, and (3) manganese dioxide.
