Drinking Water Disinfection [Case Studies White Paper]

  1. Hydro-Guard Advanced Flushing System Simplifies Operations, Increases Water Quality And Saves Treatment Expenses
    4/24/2014

    Birmingham Water Works Board (BWWB), Birmingham, Alabama has consistently achieved the rating of the number five water system in the United States for water quality.  BWWB’s potable water distribution system (WDS) serves 600,000 people with a daily average use of 100 million gallons (378 million liters) of water, received from nearby lakes and rivers. The system includes 51 water storage tanks, nearly 4,000 miles (6,437 km) of pipe, over 13,000 fire hydrants and over 200,000 service connections.

  2. Update And Upgrade Of Ozone Dissolution System At Southwest Water Treatment Plant
    4/24/2017

    The burden of the unavailability of replacement parts for the aging generators and the FBD basins' high maintenance motivated the Orlando Utilities Commission's Southwest Water Treatment Plant to update and upgrade the plant’s ozone system.

  3. Treatment Of Cyanotoxins In Drinking Water With Activated Carbon
    9/24/2014

    Recently, cyanobacteria and cyanotoxins have become a high profile drinking water quality concern in both the United States and abroad. The combination of weather conditions, agricultural phosphate runoff, and other factors has produced water conditions that have favored the formation of cyanobacteria in surface water supplies.

  4. 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.

  5. Ozone To Enhance Removal Of Iron And Manganese And Reduction Of THM
    4/27/2017

    The U.S. EPA's promulgation of the Stage 2 Disinfection By-Products Rule required  the Public Works Department of Danvers, MA, to establish a Two-Phase upgrade of the plant’s treatment process in order to comply.

  6. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)
    12/12/2016

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.

  7. Direct Filtration Of Spring Water
    10/23/2012

    The Franklin Water Treatment Plant, near the Utah/Idaho state border, serves approximately 600 residents. Traditionally, water was drawn from springs and chlorinated.

  8. Microcystin Concentrations Following Treatments Of Harmful Algal Blooms
    6/16/2015
    Microcystin producing cyanobacteria blooms were sampled and tested from an Illinois reservoir, an Ohio reservoir and a Michigan lake.
    The Question: Should the fear of "releasing" microcystin deter an algaecide application?
  9. 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.

  10. Drinking Water Disinfection - Coquitlam Water Treatment Plant, British Columbia (Case Study)
    11/7/2011

    In 2005, in response to changes to the Canadian Drinking Water Quality guidelines, the Greater Vancouver Water District Board approved a proposal to upgrade the Coquitlam WTP with UV disinfection technology to act as the primary means of disinfection.
