摘要： A system is described for the treatment of fluorochemicals in an aqueous environment, the system includes: a first treatment station configured to receive a first stream or volume of water comprising fluorochemicals, the first treatment station configured to provide a first treatment to the first stream or volume of water to thereby provide a second stream or volume of water comprising fluorochemicals; and a second treatment station configured, to treat the second stream or volume of water by ultrasonically induced cavitation at a frequency within the range from about 15 kHz to about 1100 kHz. A process for the treatment of fluorochemicals in water is also described, the process comprising: applying a first treatment to a first stream or volume of water comprising fluorochemicals, the first treatment producing a second stream or volume of water comprising fluorochemicals; and applying a second treatment to the second stream or volume of water, the second treatment comprising ultrasonically induced cavitation at a frequency within the range from about 15 kHz to about 1100 kHz to thereby breaking down the fluorochemicals into constituent components. The first treatment station is a filtration station, a reverse osmosis station, an ultrafiltration station or nanofiltration station.

摘要： Systems and processes for the removal of fluorochemicals from water are provided. Systems according to the invention include a vessel containing the ion exchange resin, the ion exchange resin including an insoluble matrix having functional groups bonded to the matrix, the functional groups being amines of the formula: N(R1R2R3) Where N is nitrogen; and R1, R2 and R3 are hydrocarbon groups and can be the same or different, normal, branched and/or partially or fully substituted (e.g., fluorinated) and having a carbon chain length of C1 or greater, the hydrocarbon chain optionally including polar groups (e.g., O, N, S). An inlet for directing a flow of water into the vessel is provided to facilitate contact between the water and the ion exchange resin; and an outlet is provided to direct a flow of water out of the vessel after the water is treated. A process for the removal of fluorochemicals from water is also provided by exposing water to the foregoing ion exchange resin, maintaining the water in contact with the resin for a period of time, and thereafter separating the water from the resin.

摘要： 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.
