ABSTRACT:
The water remediation and purification method includes a cavitation nozzle which is operated with a throat size and pressure drop to incur cavitation in the water. The explosive and implosive bubble growth and collapse produces free radicals which interact with contaminants in the water to oxidize the contaminants. The cavitation process is enhanced by (1) a variable throat nozzle, (2) recycling the product back through the nozzle for further oxidation, and (3) programmable control feedback. Subsequent ultraviolet radiation from high energy lamps, ion exchange and/or degassifying treatment can be employed to produce water quality within acceptable levels.
