  • Liqui-Cel® membrane contactors can help meet pure steam requirements in pharmaceutical industry

    Pure SteamPure steam is used in sterilization chambers as a common method to sterilize pharmaceutical products, such as equipment parts, instruments, containers and materials for sterile environments. Although regional Pharmacopeias in Europe, Canada, Japan, India and China have minor differences in limits and measurement techniques, they each have similar specifications on pure steam ...

  • TB 50: Taiwan o2 co2 removal case study

    A semiconductor plant in Taiwan is using Liqui-Cel® Membrane Contactors to remove dissolved gas from their ultra pure water (UPW) system. The UPW system is used to purify water used in the chemical mechanical polishingprocess (CMP) at the fab. The water system was designed and built by United Purification Technologies in Taichung Taiwan. The water system has two degasification stages. The first ...

  • TB 43: Efficient ammonia removal using modular liqui-cel contactors

    Ammonia is widely used in the Chemical Industry as a cleaning and bleaching agent in the production of fertilizers, plastics, and explosives just to name a few. As a result, large quantities of wastewater containingammonia are produced and many industries now have to treat the wastewater to remove the ammonia so that it is not discharged back into the environment. There are many conventional ways ...

  • Spiral-Wound Elements for Potable Water Treatment

    Introduction Any new technology must overcome perceptions of the marketplace, which are not accurate. As a technology moves into new areas of application, new misconceptions also arise. Crossflow membrane technology is no exception. The first man-made, pressure-driven 'crossflow' membranes were made in flat sheet form. This membrane had to be configured in a device, and was first made in ...


  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...
