  • Patent number: 9827517
    Abstract: A filtration apparatus and filtration method can be used to reduce at least one contaminant (e.g., organic molecules, ions and/or biological microorganisms) in an aqueous fluid. The filtration apparatuses and methods of the invention can separate at least one contaminant from an aqueous fluid and/or oxidize at least one contaminant. In operation, an aqueous fluid is flowed through a filtration apparatus comprising a porous carbon nanotube filter material at an applied voltage. In some embodiments, the filtration apparatus described herein can be used for dead-end filtration. In some embodiments, the filtration apparatus described herein can be used for cross-over filtration.

  • Publication number: 20100096337
    Abstract: A system for the treatment of groundwater is described, the system including: a first component for placement into a groundwater table, the first component having a first end and a second end and an interior space defined by an inner wall and extending between the first end and the second end; at least one ultrasonic transducer positioned with the interior space of the first component to provide ultrasonically induced cavitation to a volume of water within the interior space; a pump associated with the first end of the first component to draw water from the groundwater table into the interior space of the first component; an outlet associated with the second end of the first component, the outlet positioned to direct a volume of water away from the first component after the water has passed therethrough; a power supply; and a radio frequency generator capable of providing a radio frequency within the range from about 15 kHz to about 1100 kHz.

  • Publication number: 20100089841
    Abstract: A process is described for the treatment of fluorochemicals in an aqueous environment, the process including the steps of (1) ultrasonically inducing cavitation in an aqueous system at a frequency within the range from about 15 kHz to about 1100 kHz, the aqueous system comprising fluorochemicals; and (2) breaking down the fluorochemicals into constituent components by the application of the cavitation. The ultrasonically induced cavitation is performed at a frequency within the range from greater than 200 kHz to about 1100 kHz. The process can be used to facilitate the degradation of any of a variety of fluorochemicals having a carbon chain length of C2 and higher.
