  • Process for rapid colloidal suspension removal
    Patent number: 6607670
    Abstract: A method and apparatus is disclosed for very rapidly cleaning very small, colloidal particles from nuclear reactor water subjected to a high-energy waterjet cutting of metal using metal shot particles for cuffing such as garnet particles with the cutting causing fracturing of the metal shot as well as the cut metal fines into a negatively charged colloidal suspension having a large area. This colloidal suspension causes water turbidity and makes known filtration techniques impractical for rapid removal of such suspensions for recycling to the reactor.
