<p>An ultra-filtration vacuum system (101) with a first liquid stage filter (103) has structure (113) to direct particle laden air into a vortex in a circular cyclone chamber (115) over a surface of a first liquid filter medium (125) to direct particulates in the air to a wall (119) of the cyclone chamber (115) for collection by the first liquid filter medium (125). An open pore labyrinth filter (205) is provided for further filtering air from the first liquiq stage (103). A second liquid stage (105) is provided to filter air from the labyrinth filter (205) and has a dispersion chamber (171) with an inlet that directs the particle laden air from the labyrinth filter (205) directly into a second liquid filter medium (169) to transfer momentum of the air directly to the second liquid filter medium (169), the dispersion chamber (171) having surfaces (165, 167) against which medium (169) is propelled by the energy of the injected air to disperse the medium (169) in the air, the dispersion chamber (171) shaped such that a cascading and undulating liquid surface is formed.</p> |
