Drinking Water Treatment Case Studies and White Papers

  1. Two-Way Fixed Network Helps Texas Community Become ‘City Of The Future’
    4/11/2014

    In January 2014, the city of Meadows Place, Texas, became the first city in Fort Bend County to fully convert to an Advanced Metering Infrastructure (AMI) fixed-network system. At the same time, the city also implemented a complete meter change-out for its 1,600 customers. Both projects represent large initiatives for the self-proclaimed “little city” with a population of 4,600 citizens.

  2. How To Clean And Handle pH Sensors
    10/31/2017

    For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.

  3. Known For “Healing Waters,” Pagosa Springs Restores Its Potable Water System With Help From SolarBee® Mixers
    10/8/2014

    Located in the high desert plateau of southwestern Colorado, Pagosa Springs is famous for its geothermal hot springs, which draw visitors worldwide to soak in the mineral-rich water. The Utes called the sulfur springs “Pah-gosah,” meaning “healing waters.” You might say the town’s potable water system is healed now as well.

  4. Replacement Of Gas Chlorination System: City Takes Advantage Of Special NaOCl Dosing Unit
    4/5/2012

    Operations management for a municipal direct water filtration plant reports achievement of a reliable and cost-effective change in chlorination systems that has continued to provide for effective disinfection, while better meeting safety and efficiency criteria. By Cliff Lebowitz

  5. City Solves Reliability And Maintenance Problems For WTP Hypo Feeds
    8/13/2014

    A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.

  6. How To Clean, Inspect, And Calibrate pH Sensors
    4/2/2012

    Once a pH sensor is installed in the process and operating, how do you determine when it is time to take the sensor out of the process and do a cleaning, or a calibration? Does one perform both a cleaning and a calibration or just a cleaning, or just a calibration? By Fred Kohlmann - Analytical Product Business Manager

  7. Is Manual Calibration The Right Choice For You?
    4/12/2017

    When selecting a new analyzer for your plant, there are many different features to consider. One of those is the choice of how the instrument will be calibrated, namely between an inexpensive manual calibration and a more complex automatic calibration method. (To be clear, we will define automatic calibration as a feature that involves no operator intervention at the instrument.) Factors that influence this choice are financial, process, staff levels, and personal preference. Let’s explore each of those.

  8. 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
  9. 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. By Aquatech International Corporation
  10. Groundwater Remediation - Stockton, California (Case Study)
    12/12/2012

    In the early 1990’s, the volatile organic compounds (VOCs) tetrachloroethylene (PCE), and trichloroethylene (TCE) were discovered in the vicinity of several city water supply wells near the city of Stockton, California.
