    The North Texas Metropolitan Water District began working to add ozone to its four interconnected water treatment facilities which operate as the Wylie Water Treatment Plant (WTP).

  2. Baja California, Mexico Addresses Water Scarcity, Partnering With Fluence
    11/12/2015

    When the government of Baja California, Mexico, declared a water emergency for the region of San Quintín in 2014, leaders knew they needed to find a solution to ensure residents a reliable, safe water source.

  3. Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber
    4/16/2014

    The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.

  4. Upgrading DWTP Operations In Kansas With The QbD1200 TOC Analyzer
    7/26/2017

    For drinking water treatment plants (DWTPs), the EPA’s Disinfection Byproduct Rule (DBP) is a way of life. Unfortunately, for many facilities the equipment and operations haven’t evolved with the regulation mandates, leaving facilities in a tough spot. For a DWTP in Douglas County, KS, its challenges with accurate TOC measurement and testing, along with expensive calibrations and extended downtime with its prior TOC analyzer led it to trialing the Hach QbD1200 TOC Analyzer. Read the full case study to learn more.

  5. TotalCare Condition Audit Results In Energy Savings Of 80% And Improved Controls
    5/1/2017

    Xylem TotalCare Condition Audit, an inspection and recommendation program that helps plant operators find ways to lower maintenance costs by identifying inefficiencies in the operation of water and wastewater equipment, was elected to audit the American Canyon Wastewater Treatment Plant (WWTP) in California.

  6. Project Profile: Berea, Ohio Detects Cryptosporidium In Source Water, Installs ETS-UV™ Systems For Protection
    2/3/2017

    First settled in 1836, the City of Berea, Ohio gained acclaim as being the source for dimensioned stone formed from locally quarried sandstone, notably grindstones. The grindstones were shipped to Cleveland by oxcart and, as demand grew, later by a purpose-built railroad to the Big Four Railroad across the Midwest. Now many of the former quarry pits are better known as Baldwin Lake, Wallace Lake and Coe Lake.

  7. Ozone-Biologically Active Filtration For Potable Reuse In California's Inland Communities: Benefits And Barriers
    5/17/2016

    California’s inland communities have been hit hard by four years of drought, lower groundwater levels, and reduced allocations from the State Water Project.

  8. MEMCOR® Continuous Microfiltration System Maximizes Water Resources For The City Of Scottsdale, Arizona
    3/26/2013

    The desert community of Scottsdale, Arizona had no natural surface water sources and a decreasing groundwater supply. Scottsdale had historically treated and disposed of its wastewater.

  9. Degas Separator Selected For Wichita Aquifer Storage And Recovery Project
    4/26/2017

    In the 1990s, the City of Wichita, KS, developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the Little Arkansas River.

  10. Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)
    7/7/2010

    The Region of Peel is the second-largest Canadian municipality after the city of Toronto, and draws its drinking water from Lake Ontario — the smallest of the five Great Lakes. To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region decided to upgrade and expand its water treatment plant. To deal with seasonal taste and odor compounds produced by algae blooms in Lake Ontario, the membrane plant will be equipped with a Trojan UV-Oxidation system.
