  2. 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.

  3. Targeted Algal Management Plan To Address Taste And Odor Problem
    6/16/2015

    Lake John Hay is located six miles northwest of Salem, Indiana and is used for drinking water and tournament and recreational fishing. With an average depth of 14-15 feet, it is ideal for algae and plant growth. The persistent, recurring algae blooms was causing taste and odor problems, which led to frequent complaints.

  4. State-Of-Art Filters Triple Filter Run Times And Maximize Performance
    3/16/2017

    A plant manager in Colorado became frustrated by the consistently short filtration run-times and the large amount of water wasted by the four dual-cell bottom filters used to clean the region’s drinking water. Xylem’s Leopold Type XA underdrain with I.M.S 200 media retainer, new filter media (12” silica sand/18” anthracite), and wash troughs, emerged as the top choice.

  5. Why Pilot Test Prior To Purchasing A Water Treatment System?
    3/20/2013

    There are a number of advanced water treatment tools available today that were not available 10 years ago, which broaden the approach to finding the most effective and least expensive treatment alternatives. Pilot testing of various technologies is the most beneficial method to determine the efficiency of treatments.

  6. Ozone Disinfection System Provides Second Stage Treatment For Water Treatment Plant

    Tampa Bay Water’s state-of-the-art surface water treatment plant has provided high-quality drinking water to the Tampa Bay region.

  7. Membrane Filtration Water Treatment Plant Meets Hotel Complex's Needs
    10/23/2012

    The Little America West Hotel complex located near the town of Granger, Wyoming, used an outdated surface water treatment plant that provided poor quality water during storm events.

  8. The Benefits Of Reusing Wastewater
    1/16/2015

    Since water is an essential element in food or beverage operations, reusing it can reduce a business’s water usage ratios, help meet sustainability goals, lower supply risk and contribute to cost savings, making it a top priority for many companies today.

  9. An Energy System For Power Generation Relies On Quality Monitoring Instruments From Siemens
    11/23/2015

    A U.S. company develops energy technologies that are environmentally sustainable and provides their customers with the ability to use their energy sources in a more practical and cost-effective manner.

  10. How Meter Nozzles Can Deliver Accuracy In Municipal Treatment Facilities
    5/16/2013

    The United States Environmental Protection Agency claims there are approximately 155,000 public water systems in the nation and the public drinking water systems regulated by EPA provide drinking water to 90 percent of Americans. To put this in perspective, a family of four statistically uses 400 gallons of water daily. By Jeff Smith, Primary Flow Signal
