  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • Indoor Air Quality and Hazardous Gas Detection

    Indoor air contaminants come in a variety of forms and originate from multiple sources. Interactions between building materials and furnishings, activities and equipment inside the building, internal temperature and relative humidity, filtration and ventilation system operations, climate and building occupants all contribute to the indoor air quality (IAQ) in commercial, industrial, residential ...

  • Gravity driven membrane filtration system to improve the water quality in rainwater tanks

    The characterisation of rainwater in metropolitan Sydney and in rural New South Wales was undertaken. The results showed that factors such as the lack of vehicular traffic, air pollution and urban contamination meant that rural rainwater water quality was better. The rain water collected in both metropolitan and rural areas generally complied with the 2004 Australian Drinking Water Guidelines ...

  • Hydrocarbon evaporative emissions & control for automotives

    Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...

  • Ethylene removal in domestic refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit.
