Drinking Water Application Notes

51. Oxidation Reduction Potential 10/29/2021

    What is ORP? Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.

52. Recording & Control: In Coagulant Dosage Applications For Potable Water Treatment 7/1/2019

    Potable water or drinking water as it is also known, is water that is safe to drink or to be used in food preparation. Typically, in developed countries, tap water meets the required drinking water standards, although only a small proportion is actually drank or used in food preparation.

53. Pile Cloth Media Filtration Removes 97% Of Microplastics From Wastewater 12/6/2023

    Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.

54. Drinking Water Testing By Ion Chromatography Using Ultrapure Water 9/29/2022

    This application note demonstrates the suitability of ultrapure water produced by a Milli-Q IQ  7000 water purification system for the IC analyses of inorganic ions and DBPs in drinking water.

55. Leak Detection On Water Distribution Network Using Clamp-On Flowmeters 5/22/2023

    A global engineering company realized that their leak identification methods were time consuming and expensive, and so began to explore alternative solutions, such as ultrasonic flow meters. 

56. How Activated Carbon Works To Purify Air And Water 10/31/2019

    The first step is to define the performance limiting factors in the application. For this application, most of the adsorber is used for MTBE adsorption in the ppb concentration range. Adsorption of BTEX, TBA, or humic acids or other total organic carbon (TOC) components are removed by the front end of the column.

57. Immediate pH Correction For Fluctuating Flow 2/19/2014

    In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements.  Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.

58. Dosing Of Sodium Hypochlorite Solution For Drinking Water Disinfection 9/22/2022

    A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

59. Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE) 12/30/2013

    Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

60. Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS 10/1/2014

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
