  • Nitrate is the most prevalent pollutant of ground water in the United States and is very common worldwide. Common sources of nitrates are fertilizers animal feedlots municipal wastewater and septic systems. The level of nitrate is regulated in drinking water because high nitrate levels are known to cause Methemoglobinemia a disease that prevents blood from collecting and carrying oxygen efficiently. Another disease caused by high nitrate levels is Blue Baby Syndrome this malady causes an increase in bacteria which convert the nitrate into nitrite and poisons infants.

  • Technology

    The widespread distribution of perfluorinated compounds (PFCs) in the environment has ignited health concerns and has caused the government to set stricter standards of acceptable PFC concentration in municipal water. In 2009 the EPA published that only values of 0.4 µg/L for PFOA and 0.2 µg/L for PFOS are acceptable in drinking water. The decreased standard raises a need for better perfluorocarbon water filtration technology. Technology Description: Faculty at the University of Arizona have proposed a sorbent to effectively remove perfluorinated compounds from water.

  • Technology

    Water purification and water treatment processes influence the quality of everyday life. While there have been many recent advanced developments in water purification and treatment they are expensive and not applicable on a large scale. There is a strong need in industry for improved water purification and treatment processes for drinking water as well as wastewater in general that remove a variety of contaminants. Researchers at Arizona State University have developed an exciting ion-exchange media that simultaneously removes strong acids and oxo-anions from water.

  • Technology

    The technology is an energy efficient water purification method that can be used for large-scale commercial application. The process works by boiling the contaminated water to destroy the presence of bacterial or parasitic organisms and then instantaneously cooling it. It uses CO2 as the heating agent as well as the refrigerant. In a heat exchanger compressed CO2 is used to boil water to 116 ˇ C destroying any harmful bacteria. The water is then cooled in a radiator by using a fan. The liquid CO2 is throttled to reduce its pressure and subsequently cooled to around 5ˇ C.

  • Summary: More and more chemicals of various origins are being discharged into our local water streams ending up at waste and water treatment facilities. These chemicals comprising of pharmaceuticals personal care products and other various industrial chemicals are currently not removed by typical wastewater treatment practices. Further current regulations from the Food and Drug Administration do not require testing or removing these chemicals even as their amounts aggregate in our drinking water.

  • Objective
    Technology

    Unique particles derived from acrylonitrile or other materials which are capable of selectively absorbing uranyl from groundwater surface water and wastewater.Applications:This technology can be used to improve the quality of a water supply by safely effectively and inexpensively removing uranyl ions from the water. The presence of uranium in groundwater is a growing problem in the United States and one without effective treatment to date. These particles can also be used in portable field systems for analysis of uranyl content on site.

  • Objective
    Technology

    Chemical contaminants such as nitrogenous wastes found in aquacultures or groundwater may contaminate nearby areas and drinking water supplies. Groundwater pollution may be caused by activities such as industrial waste disposal accidental spills fuel tank leakage or application of fertilizers herbicides or pesticides to crops. Natural causes such as arsenic also may result in groundwater contamination. Organisms are a major cause of water and aqueous environment contamination and are one of the world’s largest health concerns.

  • Objective

    This invention provides compositions and methods for inducing and enhancing order and nanostructures in block copolymers and surfactants by certain nonpolymeric additives such as nanoparticles having an inorganic core and organic functional groups capable of hydrogen bonding. Various compositions having lattice order and nanostructures have been made from a variety of copolymers or surfactants that are mixed with nonpolymeric additives.

  • Objective
    Technology

    The on-line monitoring capability of heavy metal ions would be of interest to the laboratory water market. Heavy metal ions are a cause of environmental pollution from a number of sources including lead in petrol industrial effluents and leaching of metal ions from the soil into lakes and rivers by acid rain. The concept of stripping voltammetry is a well understood and highly respected technique that has been applied for trace level detection of heavy metal ions such as zinc lead cadmium copper mercury arsenic etc.
