  1. Long-Term Performance And Boron Rejection Of LG SWRO Membranes In Malta Desalination Plants
    9/4/2018

    Malta is an archipelago of three islands situated in the Mediterranean Sea, around fifty miles south of Sicily. There are no rivers of any significance on the islands, and the sparse annual rainfall is only about 500 mm. In order to bridge the gap between supply and demand, Malta has long ago started desalination of seawater. The technologies were initially based on evaporation. In 1981 the Government decided to invest in RO desalination capacity.

  5. Installing Hydro-Guard® Automatic Flushing Saves Rural Texas Town $8,000 A Year
    9/11/2015

    Managed by the private, non-profit South Jasper Water Supply, Buna, Texas’ water system contains 91 miles of un-looped distribution pipe with historical water losses of up to 30%. A small operations team is responsible for monitoring two water plants, reading 700 meters, repairing leaks, and flushing water to control the water quality. In an effort to spend less time manually flushing hydrants and focus more time on repairing leaks to reduce non-revenue water loss, South Jasper Water Supply purchased and installed two (2) Hydro-Guard® HG-1 Basic/S Flushing Systems.

    A timeline of 120 days. Construction in the middle of winter, when temperatures were frigid and snow covered the ground. Despite these challenges, Elite Excavating Company of Ohio, Inc., was able to install 174 AMERICAN Flow Control American-Darling MK 73 fire hydrants and 280 resilient wedge gate valves in sizes 6 to 18 inches in three months.

  7. Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China
    6/17/2016

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  8. AMR System Delivers Outstanding Efficiency While Improving Water Conservation In Pacific Northwest
    2/12/2014

    Public Utility District No. 1 of Skagit County (Skagit PUD) in Washington state was at a crossroads, facing a number of challenges related to its meter reading system. Because the utility was using a touch-read/visual-read system, it was highly dependent on its water meter readers’ acquired route knowledge. Two of the PUD’s three meter readers were planning to retire soon, and it would take at least a year to hire and train new employees to fill their experienced shoes. At the same time, the community was growing at a steady pace, and a significant number of its existing meters were reaching the end of their useful lifecycle.
