Drinking Water Application Notes

  1. LC-MS Analysis Of PFAS Compounds In EPA 533 After Supelclean™ ENVI-WAX SPE Cleanup 8/29/2022

    This application note demonstrates the extraction and subsequent analysis of 25 related analytes from water using Supelco SPE cartridges.

  2. Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants 1/15/2019

    Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

  3. 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.

  4. Phosphate In Groundwater And Surface Water: A Rapid And Reliable Determination Method Using The Photometric Spectroquant® Test 1/31/2019

    Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO4-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.

  5. 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.

  6. Optimization Of Water Treatment Using Zeta Potential 5/27/2020

    Drinking water in the US and developed nations of the world is treated to remove contamination of foreign materials, both mineral and organic.

  7. Pipe Repair On A Budget 3/7/2014

    A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

  8. Automatic Rinse Tank Controls 10/29/2021

    Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored.

  9. Application Note: Desalination Plants: YSI Instruments Monitor Flow & Water Quality At Multiple Stages 2/3/2011
    Desalination is the process of removing salt from sea water or brackish river or groundwater to make potable water. By YSI
  10. UV Technology Offers Solution For Emerging Water Crisis 2/19/2014

    Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.
