Lead Paint Removal by Confined Hydraulic Jet. Phase 1
Abstract
This Phase I feasibility study examined a confined hydraulic jet as means for stripping lead-based paint from wood surfaces without dispersing debris (paint chips and wood splinters) into the ambient. Laboratory tests verified the capability for removing and concentrating the hazardous lead component. However, paint removal was accompanied by gouging of the wood substrate. The technique can be applied for preparation of older wood buildings (military, inner-city) prior to demolition and cleanup of chemically contaminated building interior and exterior surfaces. A separate effects approach used small (14 x 14 cm), painted wood panels (pine, fir plywood. and oak) for studies over a range of hydrojet characteristics and operating parameters. The apparatus was assembled from standard commercial components. Tests were done at pressure levels from 500 to 1500 psi (3.5-10.5 MPa) using a 15-degree fan spray nozzle at nozzle-surface separations of 1 to 3 in. (2.5-7.6 cm).
