Abstract

A liquid blasting system for blasting an area, surface, structure, part, item, or member with liquid or with liquid and abrasives, or with a liquid-abrasive mixture. The system has a housing through which are disposed a plurality of inlets or nozzles. Liquid, e.g. water, under pressure is transmitted through the inlets or nozzles to the area, etc. to be blasted. Abrasives, e.g. sand, may be injected with the liquid or separate abrasive injection inlets or nozzles may be employed in connection with the liquid inlets or nozzles. The inlet or nozzle housing can communicate with a collection housing for receiving blasted material, liquid, and abrasives and the collection housing can have ports therein through which these liquids and materials can exit. The ports can be suitable for connecting thereto a vacuum source for sucking materials and liquid from the nozzle housing, to and through the collection housing, and thence out of the collection housing.
