Drinking Water Application Notes

1. Reduce Or Eliminate Water Hammer With Valve Positioners 5/19/2022

   Water hammer, which can occur in just about any pumping system and even steam systems, can lead to pipe breakage, equipment damage or even total system failure. Addressing water hammer at the source is the savviest and most cost-effective way to handle the issue.

2. 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.

3. Flow Monitoring At Sea Water Reverse Osmosis Plant Improves Water Distribution 1/6/2025

   Read about a desalination plant that was in need of a practical verification methodology for permanent and/or temporary (portable) solutions on large pipes.

4. Panametrics Technology Helps Track Potable Water Leaks 4/22/2022

   Concerned about the volume of water leakages throughout their network, a Swedish water authority turned to Panametrics flowmeters to map their municipal water network -- enabling quick leak identification and fixes.

5. 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.

6. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water 4/5/2013

   Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

7. 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.

8. 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.

9. UV Advanced Oxidation For Surface Water Remediation 5/15/2026

   Surface water contamination demands advanced treatment solutions. Learn how UV advanced oxidation simultaneously destroys complex micropollutants and inactivates pathogens in a single step, offering a scalable, cost-effective alternative that eliminates chemical residuals and reduces seasonal operating expenses.

10. 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.
