Abstract
The present system relates to a water and debris recovery system for a water blasting device suitable for mounting upon the frame of a mobile vehicle for easy transport and use. The system includes a liquid reservoir connected to a high pressure fluid pump for directing ultra-high pressure water through a blast head to remove the coatings or markings from a surface. The blast head includes a shroud which surrounds the blasting area to at least partially contain the water and debris dislodged from the surface. A vacuum pump is secured to the shroud with the vacuum passing through a cyclone type separator, allowing the water and debris to settle to the bottom portion of the cyclone. The tank includes a floating floor and bladder assembly that allows the same space to be utilized for clean as well as dirty water while maintaining separation of the two.
