Abstract
Apparatus and a method for separating particulates from a fluid in which the particulates are entrained. An impact collection surface is coated with a material that improves the efficiency with which the particulates are separated from the fluid and collected. In one embodiment, the coating retains the particulates when dry, but readily releases the particulates when wetted with a liquid. In another embodiment, the coating is a material that has a relatively low coefficient of friction, so that the particulates that have impacted on the coating are readily washed from it with a liquid. The coating may be selected to retain specific biological particulates by including an antibody that selectively links with antigens on the biological particulates. The coated impact collection surface may be used to purify water by removing biological contaminants and other particulates from the water passing over the coated impact collection surface. In one embodiment of a particle impact collector using coatings like those just described, the coated impact collection surface is on a flexible tape that is moved past a point of collection and onto a take-up reel.
