ABSTRACT:
Method and apparatus for the removal of a liquid film disposed upon a road surface, preferably, environmentally unacceptable anti-freeze solutions such as ethylene glycol upon an airport apron. Apparatus comprises a unit for spraying the road surface with a fluid, preferably, water, and collecting the solution disposed upon the surface. The apparatus comprises a housing defining an inner chamber and having a lower edge operably adjacent and in close proximity to the surface and a portion defining an outlet operably in communication with extraction means by which the liquid is extracted from within the inner chamber; and spray means adjacent the housing for spraying the fluid at such a pressure upon the surface as to effect agitation and dispersal of the liquid in particulate form above the surface within the inner chamber for extraction through the outlet. The invention also includes the apparatus when part of a self-contained mobile spray and collection system.
