Drinking Water Treatment Application Notes

  1. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution
    9/17/2014

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  2. 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.

  3. The Basics: Testing RO Quality

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.

  4. VFD Energy Savings For Pumping Applications
    4/6/2017

    In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

  5. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives
    4/1/2017

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

  6. Advances In Paper-Based Devices For Water Quality Analysis
    2/22/2017

    Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

  7. Disinfection In Drinking Water: Choosing The Right Chlorine Analyzer For Your Application
    4/13/2017

    Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.

  8. Protecting Pumps From Dead Head Conditions
    4/6/2017

    The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

  9. Chinese Chemical Plant Optimizes Water Treatment By Replacing Double Pass RO With A Single Pass RO And 3M Liqui-Cel Contactor System
    6/1/2016

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment.

  10. 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.
