  • Semiconductor Water Purification and Reverse Osmosis

    A 5 page paper discussing advances in the purification of water used in the manufacture of semiconductors. Today's reverse osmosis technology is greatly more advanced than that of only a decade ago when membrane pores were large and no other filtration system, such as activated carbon, was used in parallel with reverse osmosis. The technology for the filtration process, as for semiconductor manufacturing, has improved to a level that today it provides an effective and cost-efficient method of purifying water used in the manufacture of semiconductors. Bibliography lists 10 sources.

  • Domestic Wastewater Problem and Concept of Sustainability

    A 10 page overview of the concept of sustainability in relation to the treatment and disposal of domestic wastewater. Identifies two more sustainable alternatives than conventional chemical treatment and disposal into water bodies: reverse osmosis and manmade wetlands. Bibliography lists 5 sources.

  • Osmosis Defined

    This 5 page report discusses and explains the concept of osmosis which is how one element or ingredient of a solution flows through a membrane while other components of a solutuon are shut out and unable to pass through the membrane. In order to determine which membranes allow the flow of which constituents of a solution requires experimentation since not all membranes act the same way. Bibliography lists 8 sources.

  • Chemical Toxic Threat of Mercury

    Mercury is a known neurotoxin and for this reason, it has been targeted by the Environmental Protection Agency (EPA) as a primary toxic exposure threat. Mercury is transferred through multiple means including ingestion, airborne, and osmosis through the skin. Mercury toxins are released into the air naturally, as well as through car and other exhaust. Mercury is a component of computer chip manufacturing and for the IUB, it is served in the cafeterias and restaurants around campus via fish. The National Research Council cites prenatal exposure effects ranging from mental retardation and cerebral palsy to deafness and blindness.... 9 references. jvToxThr.rtf
