Drinking Water Case Studies and White Papers

  1. Case Study: Chemplast Chooses Aquatech’s HERO™ & ZLD
    7/3/2009
    The Chemplast Mettur plant uses the Cauvery River as their main fresh water source. A strong industrial growth in recent years has resulted in water scarcity in the region. Industries are also required to follow strict environmental norms for discharging effluents. The intent of a Waste Water Treatment Plant was to have complete treatment, recycle and reuse of the combined waste water streams to reduce intake from the Cauvery River while not discharging any liquid waste streams.

  2. Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon
    4/3/2014

    Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

  3. New Electromagnetic Water Meter Technology Improves Accuracy And Reliability
    12/26/2012

    Electromagnetic water meters are becoming more and more popular for bulk measurement of residential and commercial drinking water, especially as pricing and metering gain traction as tools for more efficient use of water and water conservation.

  4. Guaynabo WTP In Puerto Rico Saves Thousands With UV 254 Monitoring Package
    10/22/2013

    Dealing with fluctuating water sources is not an easy task for plant operators. Seasonal variation, heavy rain fall or accidental contamination events change the raw water quality, requiring immediate attention. This is a familiar scenario for Facility Manager, Nancy Ma. Cáceres Acosta at the Los Filtros Water Treatment Plant in Puerto Rico. She has been producing highquality water for 256,000 local residents, receiving surface water from the Guaynabo and Bayamon River

  5. Chlorine vs. Chloramine: A Tale Of Two Chemistries
    4/17/2018

    In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.

  6. What's Faulty — Your Treatment Or Your Testing?
    9/29/2017

    The primary reason for laboratory testing at a water or wastewater plant is to determine if the facilities are meeting regulatory limits. Both proper operation and accurate testing are of utmost importance to ensure compliance. However, regulators and operators must consider limitations of the test methodology, as they may affect analysis results. The last thing any plant manager wants is unwarranted problems as a result of faulty analysis.

  7. New Membrane Technology Handles High Solids, Aids Water Reuse
    2/18/2015

    As global conditions place more stress on water resources, a great deal of attention is being paid to water reuse technologies, particularly those that facilitate the reuse of the next level of difficult-to-treat or highly variable raw water sources.

  8. CleanFlo™ Monoscreen® Case Study
    12/22/2014

    When the polar bears at the Brookfield Zoo were introduced to their new habitats at the Great Bear Wilderness, they had no idea how much more fulfilling their life would become.

  9. Water Quality Is Key To The Success Of Cardiff Bay Restoration
    10/12/2011
    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in 1987.
  10. Validation Of Online Monitors Using EPA 334.0 And EPA-Approved Or Accepted Laboratory Meter Reporting Methods
    8/25/2010
    There has long been verification testing between lab and online instrumentation for water quality measurements, especially for Drinking Water and Wastewater (DW//WW). By Jane L. Stevens, Product Manager, Thermo Fisher Scientific
