  • Heat Sanitization Basics for Ultrapure and Pharmaceutical Water

    Even small numbers of bacteria are a problem for critical water systems like pharmaceutical USP water, dialysis water, and ultrapure water for semiconductor manufacturing. Bacteria are often killed with UV-254, chemicals, and heat. Chemical sanitization is often undesirable or prohibited, creating a steady change-over to pure water systems that can be sanitized with heat. Most ...

  • Comparison of the water purification efficiency of two different flocculation-sediment-filtration (FSF) processes in Chaohu Lake in China

    A novel biofilter (BF) with the potential to improve pollutant removal when used as a substitute for sand filters in water purification processes is presented. To investigate BF's pollutant removal performance, a flocculation-sediment-biofiltration (FSBF) process was compared with a flocculation-sediment-sand filtration (FSSF) process on a lab scale, with water collected from Chaohu Lake. The ...

  • Novel thermoresponsive assemblies of co-grafted natural and synthetic polymers for water purification

    Water contamination and its purification are a global problem. The current approach to purify water is reduction of impurities to acceptable levels. One of the ways to achieve this is by use of water-soluble polymers that extract organic and metallic contaminants, from water. This paper presents a blend of composite polymers that eliminates both the contaminants simultaneously by the principle ...

  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • Pure water from Kinetico at the Worcestershire Royal Hospital case study

    When the Worcestershire Royal Hospital opened, it had been equipped with a Kinetico water treatment system to supply pure hot water to its theatre areas and to washer disinfector units used for cleaning and disinfecting medical devices. In recent years, partly in response to concerns about the transmission of variant CJD via reusable surgical instruments; and also with regard to the risk ...

  • The role of a hybrid phytosystem in landscape water purification and herbicides removal

    The performance of a hybrid phytosystem in landscape water purification and herbicides removal was investigated. The phytosystem operating in an arboretum is located in the Minhang Campus of Shanghai Jiao Tong University, China. The phytosystem is composed of two purification stages: sedimentation Stage 1 without external air supply; and Stage 2 with an external air supply. Stage 2 is also ...
