Drinking Water Case Studies and White Papers

1. Advantages Of Thermal Dispersion Switches For Pump Protection 7/1/2014

   Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.

2. Ultrafiltration And Reverse Osmosis Testing On Tertiary Effluent From The North City Water Reclamation Plant 4/22/2016

   Ultrafiltration (UF) membranes have already gained worldwide acceptance in the treatment of drinking water for their removal of chlorine resistant pathogens such as cryptosporidium. Tertiary treatment with UF has been established, although with a lower level of knowledge and number of installations. This paper will discuss the performance of hollow fiber UF/MF membrane modules in treating tertiary effluent, and the subsequent performance of the downstream RO membranes.

3. U Of I Urbana-Champaign Implements Remote Monitoring System 8/23/2017

   The Utility Distribution team at the University of Illinois at Urbana-Champaign manage the water system which serves the entire campus. The University purchases water from Illinois American Water which is distributed across the campus for uses as diverse as chemistry labs, agricultural research, and competitive swimming complexes.

4. Deploying Iron-Based Adsorption Systems For More Efficient Arsenic Removal 11/4/2020

   Anion exchange treatment technologies produce a brine/contaminant discharge, while reverse osmosis solutions generate a concentrated arsenic reject. By comparison, the only cost of a properly designed iron-based adsorption system is periodic media changeout.

5. EPA And Canadian Researchers Partner To Ensure Effective Responses To Oil Spills 8/30/2022

   The U.S.-Canada border is the world’s longest shared border and includes four of the five Great Lakes, many rivers, additional lakes, major airsheds and migratory routes for wildlife species. In addition, there are many Native American Tribes and First Nations residents whose culture extends across the border.

6. LCRI: A Shift To Mandatory Service Line Replacement Within 10 Years 11/8/2024

   Mandatory LSL replacement is a fundamental shift from the LCR in its approach to service line replacement, moving from a trigger-based approach to a mandatory, system-wide replacement mandate.

7. World's Largest 1,4-Dioxane Treatment Initiative 9/9/2024

   Groundwater on Long Island, New York, contains the contaminant 1,4-dioxane. Despite no federal regulation, local water providers and state authorities have taken action to address contamination, establishing a state-enforced maximum contaminant level.

8. Wastewater Treatment Plant Realizes The Importance Of Using Genuine Replacement Parts In Its UV Treatment System 1/13/2020

   The Lucas County Water Resource Recovery Facility was experiencing treatment inefficiencies and staff couldn’t figure out why. The issues were stemming from the use of non-OEM, non-genuine UV lamps, quartz sleeves, and ballasts.

9. Cheyenne Board Of Public Utilities In Cheyenne, Wyoming Successfully Moves From Calcium Hypochlorite Tablets To Microclor® On-Site Hypochlorite Generation 7/24/2018

   The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.

10. How To Handle Unexpected Contaminants In Water 8/30/2022

    Read why temporary water treatment system may encounter new or unexpected contaminants that did not initially show up in samples, and what businesses can do in response.
