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

    Siemens offers 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 users will gain a broad range of process measurements and unequaled monitoring of the health and performance of those products.

53. Hemodialysis Patient Health 10/29/2021

    Controlling dialysate quality is critically important to hemodialysis patient health. Complications as minor as nausea and fatigue or as severe as metabolic acidosis and sepsis can result if dialysate composition is incorrect. All the factors that ultimately affect dialysate composition must therefore be carefully monitored and controlled: proper proportioning and mixing of concentrates with water; the quality of water mixed with concentrates to form dialysate; and the quality of water used in the reprocessing of hemodialyzers, system maintenance and disinfection.

54. Biofouling Control In Cooling Towers With A Halogen Stabilizer 10/22/2020

    Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).

55. Analyzing Total Organic Carbon In Sea Water 4/2/2015

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

56. 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.

57. 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.

58. Determination Of Polycyclic Aromatic Hydrocarbons In Seafood 4/20/2015

    Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

59. Why Should We Care About NSF/ANSI 61 Certification? 3/17/2021

    According to National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI), it's a set of standards relating to water treatment and establishes criteria for the control of equipment that comes in contact with either potable water or products that support the production of water.

60. 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.
