Drinking Water Application Notes

31. Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS 6/21/2018

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

32. The Basics: Testing RO Quality 4/28/2014

    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.

33. 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.

34. Remote Monitoring And Maintenance Through Digitalization 3/17/2020

    Siemens offers to our customers the ability to make both process measurements, and to remotely monitor the activity and health of instrumentation, whether you have a SCADA, PLC or DCS system, or not. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.

35. What Is Genclean Advanced Oxidation Disinfection Solution And What Is It Used For? 2/18/2021

    A non-toxic, advanced oxidation (AOP) formula of minerals chelated with oxygen and stabilized in an aqueous water solution. It is a viable option in industries and applications requiring a solution to challenging situations where high level effective sanitization and oxidation is required. Read more to learn how the Genclean advanced oxidation treatment solutions can be used in different applications.

36. 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.

37. Solution For Algae Blooms 12/17/2015

    Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.

38. Optimizing Brine Flow In A Geothermal Power Plant 1/27/2022

    Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.

39. 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.

40. 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.
