  • Amperometric Free Chlorine Measurement without pH Compensation
    Accurate measurement and control of free chlorine in water is critical in many applications. Amperometric sensors are a popular alternative to colorimetric analyzers since the measurement is continuous and no reagents are required, however most sensors are extremely sensitive to pH fluctuations
  • FCE TM: Groundbreaking Measurement of Free Chlorine Disinfecting Power in a Handheld Instrument
    during distribution as a. guard against future contamination. The most popular field test instruments and test. systems for judging the level of residual chlorine,. also called Free Available Chlorine (FAC), are based. on colorimetric methods whereby dyeing agents are. added to the sample being tested
  • Southeastern Municipality Uses Chlorine Dioxide to Control THMs in Drinking Water
    This municipality disinfects 33 million gallons per day of drinking water. Chlorine gas was used as the primary disinfectant for the raw water entering the plant. Free chlorine is known to react with certain organic species present in the raw water to form trihalomethanes (THMs) as a disinfection
  • Use of Chlorine Dioxide Improves Taste and Odor and Controls THMs
    This municipality disinfects between 12 and 36 million gallons per day of drinking water. The plant experienced taste and odor complaints at a rate of well over 100 per day. Chlorine gas was used as the primary disinfectant for the raw surface water entering the plant. Free chlorine is known
  • Medical Device Link . Chlorine-Free Blends for Flexible Medical Tubing
    of a polyolefin material. As yet, however, no substitute has been widely accepted as a chlorine-free replacement for PVC-based materials. Figure 1. An example of an intravenous set with the tubing bonded to a variety of IV components. In the present study, two chlorine-free thermoplastics were examined
  • Inline Chlorine Dioxide Monitoring - Pulp Bleaching
    Chlorine Dioxide (ClO2) has become the most significant bleaching agent in the pulp and paper industry for Elemental Chlorine-Free (ECF) bleaching. Different bleaching sequences must be used in the production of various pulps. This depends on the pulping process used, the residual lignin content
  • Material Recommendations for Chlorine Valves
    Metal corrosion is caused by the presence of water in a piping system. It is virtually impossible to guarantee a moisture-free system due to the moisture in atmosphere introduced during construction and installation.
  • Corrosive Environments and Corrosion Types
    Typically, metal corrosion becomes socially problematic not in harsh acidic or alkali environments but in human habitable atmospheric (humidity), temperature, ravely, rarely corrosive gases, airborne dusts, dissolved Oxyzen in water, free chlorine for disinfection, and by water dissolved elements
