A composite structure includes a substrate with pores of a first mean pore size and a coating on at least one surface of that substrate. This coating has pores of a second mean pore size where the first mean pore size is equal to or greater than said second mean pore size. When the pore size of the coating is effective to capture particulate greater than 0.2 micron, the composite may be formed into a filter effective to remove microbes from a fluid medium. One method to form the porous coating on the substrate includes: (1) forming a suspension of sinter...
1. A method for forming a porous coating on a porous substrate, comprising the steps of: (a) forming a suspension of sinterable particles in a carrier fluid and containing said suspension in a reservoir;(b) maintaining said suspension by agitation in said reservoir;(c) transferring said suspension from said reservoir to a first non-cavitating in-line ultrasonic agitator that agitates said suspension without cavitation;(d) transferring said suspension from said first non-cavitating ultrasonic in-line agitator to a selector valve;(e) selectively transferri...
