Drinking Water Treatment Case Studies and White Papers

  1. Optioneering Helps MidCoast Water Transform Gloucester Water Network Into A Reliable, Efficient System
    12/1/2015

    MidCoast Water delivers water and sewerage services to 40,000 households in the Manning, Great Lakes, and Gloucester communities of New South Wales in Australia. It also supplies 8 billion liters of water a year to Karuah in the south, Crowdy Head in the north, and Gloucester in the west.

  2. Los Osos Water Recycling Facility Manages High Volume Of RFIs And Submittals
    12/1/2015

    The Los Osos Water Recycling Facility is the final phase of the Los Osos Wastewater Project (LOWWP). The new 13-acre, USD 48 million facility will service the city of Los Osos’ new wastewater collection system, which includes sewer and recycled water lines, sewer laterals, pump stations, and leach fields. Prior to the new collection system and recycling facility, the entire city relied on a septic system. When completed, the new recycling facility and wastewater system will be operated and maintained by the County of San Luis Obispo, Calif.

  3. Continuous Analyzer Integrated Data Validation
    5/28/2015

    Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

  4. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%
    9/10/2018

    The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.

  5. Change To 3-Precursor Vacuum Generator-Feeder For ClO2 In WTP, From Batch Generator Pumping, Cuts Chemical Costs, Gains Plant Management Of Equipment
    1/22/2018

    The water treatment plants (WTP’s) manager for the city of Midlothian, TX reports significant reduction in chemical costs, gaining new management control for their generation and feed equipment, and ending a pesky maintenance burden, by switching to three-precursor vacuum generator-feed, from batch-generator-pumping, for introducing chlorine dioxide (ClO2) into their 8 MGD plant #2. As a result, he plans to make the same change at their 12 MGD plant #1.

  6. Filtration And Proper Contaminant Removal
    3/7/2013

    Proper removal of organic and inorganic contaminants from water used in consumption or manufacturing is the crucial component of the intended outcome.

  7. 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.

  8. Case Study: Optimized Quality Control In Mineral Water Plants
    4/16/2009

    Due to microbiological activity in the process, or to a lesser extent due to the reduction in nitrate levels in the raw water, nitrogen compounds may give rise to increased nitrite concentrations. By Endress + Hauser, Inc.

  9. North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation
    3/9/2015

    Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.

  10. Eaton Expands Online Training With New Online Commissioner Classes
    11/6/2017

    To help customers use variable frequency drives (VFDs) to enhance safety and reliability, Eaton is offering eLearning courses for VFD technology to support product, installation and commissioning and service knowledge. The robust online training program helps electrical distributors, contractors and industrial customers optimize the performance of VFDs.
