Abstract: A system and associated methods are disclosed for facilitating efficient collection of entrained material from an air/gas sample. In one arrangement, a method for collecting entrained material from a sample involves a dry collection cyclonic cycle combined with a period of fluid wash use. In particular, a sample is drawn into a chamber of a cyclone separator having a perimeter wall, and then a dry collection cyclonic separation cycle is performed on the sample for a period of time to separate a substantial amount of the entrained material from the sample. Subsequent to or temporally near an ending point of the dry collection cyclonic separation cycle, a fluid wash is injected into cyclone separator chamber so as to direct the fluid wash along the perimeter wall to capture material deposited on the walls and in the vortex break at the bottom of the cyclone separator.

Abstract: Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.

Abstract: An ion exchange scrubber has a housing, and a partition plate installed within the housing. The partition plate partitions an inner space of the housing in longitudinal direction into two chambers that are filled with a predetermined amount of aqueous solution.

The ion exchange resin removes a harmful substance contained in the gas. By repeatedly pumping the aqueous solution from one side chamber to the other side chamber, and immersing and cleaning the contaminated ion exchange resin in the aqueous solution, the contaminated gas can be effectively processed even with a small amount of water.

The nozzles are supplied by a high pressure pump through the piping and direct a stream of high velocity fluid against the interior surface of the ducting. Selective operation of the nozzles preferably minimizes pump capacity.

The resulting effluent is readily collected from the lower end of the ducting and disposed of in any manner desired.

Abstract: Apparatus is disclosed for rapidly collecting aerosols containing solid particles and micro organisms, such as viruses and bacteria, from relatively large volumes of air and concentrating these particulates as samples in water. This apparatus operates under conditions conducive to preserving the integrity and viability of the collected micro organisms. Ambient air containing aerosols drawn into and through the collector's interior by an air mover, is mixed with very warm air saturated with moisture and then with cold air, to cause the resulting vapor mixture to become supersaturated. This supersaturated water vapor rapidly condenses onto the incoming aerosol particles to form droplets with particles at their centers. The airstream carrying these droplets enters a cloud of air ions produced by a corona generator or, alternately, by a radioactive source emitting alpha particles.
