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. Protection Of Membrane Systems Utilized For Municipal Water 12/1/2020

    As water scarcity issues around the world become more acute, more municipalities are having to turn to alternative water sources for potable water supplies. Also, many municipalities in coastal areas are seeing the quality of their water sources degrade as sea water intrusion occurs.

53. Circuit Board Cleanliness Testing 10/29/2021

    Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.

54. How To Install A Submersible Pump In Discharge Tubes 11/28/2012

    In the fields of water and waste water technology, submersible pumps represent a viable economic and technical alternative to conventional, dry-installed pumps. In particular, they offer a number of handling advantages during maintenance and installation work.

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. Application Note: Troubleshooting A pH Electrode 1/26/2011

    Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause. Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. By Thermo Fisher Scientific

57. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution 9/29/2014

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

58. Best Practices In Moist And Wet Gas Flow 12/20/2021

    The Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

59. 'TOTEX' Is Key When Purchasing Instrumentation 4/29/2021

    There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

60. 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.
