Pure water (ultrapure water) is essential for the production of hydrogen (H2), a critical fuel for hydrogen fuel cells. Despite its importance, H2 is not readily available in nature, necessitating energy-intensive processes to generate it. There are two primary methods for producing hydrogen. Firstly, hydrogen gas can be generated through the electrolysis of water: 2 H2O (liquid) … Read more
Using Liqui-Cel™ to recover Ammonia from Industrial Wastewater. Ammonia exhibits a dual nature, functioning at times as an industrial waste material that necessitates treatment before discharge, and at other times as a valuable fertilizer in the form of ammonium sulfate. Liqui-Cel™ membrane contactors serve as a clean, safe, and effective means to convert dilute ammonia … Read more
Water for Sterilizing Medical Devices Water for sterilization has a new requirement and standard. This applies to surgical tools and instruments, and is useful to feed steam sterilizers and autoclaves. New Standard AAMI calls the new standard for water for sterilizing medical devices “Water for the Processing of Reusable Medical Devices”. This is technically AAMI … Read more

USP concurs: SnowPure’s experience says that heat sanitization should be between 72-80°C: Heat kills most bacteria at 60°C, and kills essentially all bacterial above 65°C. Two common protocols have emerged for sanitizing validated high purity water systems: 72°C for 30-60 minutes (bacteria killed in seconds) 80°C for 15-30 minutes (bacteria killed in milliseconds) SnowPure’s HTS … Read more
In México, EDI (Electrodeionización) is used to produce pure and ultrapure water for both Generación de Energía y Farmacéutica (USP PW y WFI). (Electrodeionización para Energia y Agua Farmaceutica) SnowPure works in México with OEMs to choose technologies and processes that will enable good performance and long life for RO (OI) and EDI Electrodeionization (Electrodeionización). … Read more
Measuring pH properly in pure and ultrapure water is difficult. pH is critical for process control and for preventing corrosion for example. pH of Ultrapure Water pH of Ultrapure water is 7.00. The only ions present are H+ and OH-, and since these must be in balance, the pH is 7. Don’t try to measure … Read more
Simplified, Value-Priced EDI A Complementary Technology to Portable Exchange DI (PEDI) EDI for Dealers is now a reality. Ultrapure water is a concern for water treatment companies who service critical applications such as Laboratory and Pharmaceutical. You must apply the right technology for your customers’ needs, while remaining competitive and realizing a reasonable profit. EDI … Read more
EDI, Why FCE is Important for Electrodeionization System Performance FCE is Important for EDI System Performance. Electrodeionization systems depend on conductivity, CO2, and Silica; all brought together by using FCE, or Feedwater Conductivity Equivalent. For an electrodeionization system to operate properly, the feed water must be high-quality Reverse Osmosis (RO) permeate. An RO permeate water … Read more
