Abstract:
A method for separating particulates from a fluids in which said particulates are entrained, comprising the steps of:(a) providing an impact collection surface; (b) producing a coated impact collection surface by applying a coating of a material to the impact collection surface that increases a retention of particulates impacting thereon when the coated impact collect surface is dry, but releases the particulates when wetted, said coating comprising a material characterized by being hydrophilic in a first state and being hydrophobic in a second state, said material retaining the particulates when in the first state and releasing the particulates when in the second state; and (c) causing the fluid in which the particulates are entrained to flow toward the coated impact collection surface, said particulates within the fluid being retained by the material and thus separated from the fluid.
