Drinking Water Treatment Application Notes

  1. 3M™ Liqui-Cel™ Membrane Contactors Improve Water Quality and EDI Performance
    6/27/2017

    Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.

  2. ABB Aztec 600 Manganese Analyzer Optimizing Manganese Removal Efficiency
    11/15/2017

    The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.

  3. Removal Of Chloramines With Activated Carbon
    12/30/2013

    In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.

  4. Analyzing Total Organic Carbon In Sea Water
    4/2/2015

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  5. Disinfection By-Products (DBP) Precursor Monitoring
    2/1/2013

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.

  6. Accurately Measuring Network Leakage
    6/26/2015

    The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.

  7. Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility
    4/14/2016

    This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.

  8. Hach FilterTrak 660™ Sc Laser Nephelometer Even More Practical For Ultra-Low Turbidity Monitoring
    6/7/2013

    Now compatible with the Hach sc100 Controller, the FilterTrak 660 sc Nephelometer connects as a ‘plug and play’ sensor with the universal, dualchannel controller that features an inherent power supply.

  9. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
    10/16/2014
    Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
  10. Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS
    6/21/2018

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.
