This technology provides materials and methods for the production of activated carbons from biochar where such activated carbons have specific area and pore volume characteristics. The activated carbons may be used for any purpose necessitating the need for them such as water purification air-cleaning solvent recovery catalyst supports and as an energy storage form. They may also be useful in the production of a super anode for a super capacitor or battery.

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.

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.

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.

Technology Description: Professor Cohen and colleagues have developed a compact and self-adaptive integrated water ultrafiltration and reverse osmosis (UF/RO) process and system. Designed to produce up to 18000 gallons of drinking quality water per day with no intermediate tanks between UF and RO or for UF backwash the system can be further expanded for even larger capacity. In addition the system is remotely monitored and is self-adaptive making use of advanced model-based control. Applications: Water treatment

Background: Nanoparticles synthesized in organic solvents have a wide variety of potential applications requiring aqueous solutions. There are no current phase-transfer methods currently capable of achieving highly uniform distribution of these nanoparticles in water. Technology Description: The present invention is a method of transferring hydrophobic nanoparticles into water. A small amount of excess oleic acid below critical micelle concentration is added to the organic solution containing the nanoparticles.
