Abstract
A method for removing particles or deposits from a surface having particles or deposits thereon. The method involves contacting a surface with a chemical composition sufficient to selectively dissolve and remove at least a portion of the particles or deposits from the surface. The chemical composition is compatible with the surface. This disclosure also relates to a system of specially designed equipment for removing particles or deposits from a surface having particles or deposits thereon. The disclosure is useful, for example, in cleaning porous surfaces, media for cartridge, pleated and membrane surfaces, and internal walls of tanks or filter housings.
Claims25
A method for removing particles or deposits from a surface having particles or deposits thereon, said method comprising contacting said surface with a chemical composition sufficient to selectively dissolve and remove at least a portion of said particles or deposits from said surface, wherein said chemical composition is compatible with said surface.
A system for removing particles or deposits from a surface having particles or deposits thereon, said system comprising at least one vessel, at least one enclosure containing a surface having particles or deposits thereon, one or more pumps, and one or more valves;
- said at least one vessel suitable for holding a chemical composition;
- wherein said at least one vessel is in fluid communication with said at least one enclosure, and said at least one enclosure is in fluid communication with said at least one vessel, to form at least a primary chemical composition circulation loop.
A method for removing particles or deposits from a surface having particles or deposits thereon, said method comprising:
- (i) providing at least one vessel suitable for holding a chemical composition;
- at least one enclosure containing a surface having particles or deposits thereon;
- and one or more pumps and one or more valves suitable for controlling flow of said chemical composition;
- (ii) conveying said chemical composition from said at least one vessel to said at least one enclosure containing a surface having particles or deposits thereon;
- (iii) contacting said surface with said chemical composition sufficient to selectively dissolve and remove at least a portion of said particles or deposits from said surface, wherein said chemical composition is compatible with said surface;
- and
- (iv) conveying spent chemical composition from said at least one enclosure to said at least one vessel.
A composition for removing particles or deposits from a surface having particles or deposits thereon, said composition comprising a chemical composition sufficient to selectively dissolve and remove at least a portion of said particles or deposits from said surface, wherein said chemical composition is compatible with said surface.
A media treated by a method, said media comprising a surface having particles or deposits thereon, said method comprising removing particles or deposits from said surface by contacting said surface with a chemical composition sufficient to selectively dissolve and remove at least a portion of said particles or deposits from said surface, wherein said chemical composition is compatible with said surface.
A method for preconditioning a media, said media comprising a surface having particles or deposits thereon, said method comprising contacting said surface with a chemical composition sufficient to selectively dissolve and remove at least a portion of said particles or deposits from said surface, wherein said chemical composition is compatible with said surface.
