Patent ID: 6890443

Claim:
A spin filter apparatus for cleaning an influent stream, the apparatus comprising: a housing having at least one inlet port for receiving the influent stream, at least one waste port for discharging waste and at least one output port for discharging a processed clean effluent stream; a discharge conduit coupled to the at least one outlet port for discharging the processed clean effluent stream; and a spin filter assembly disposed within the housing and including a filter screen set formed of at least two screen filters that are rotatable about the discharge conduit and freely movable in a vertical direction along the discharge conduit, the screen set being coupled to a magnetic shaft that permits the screen set to be a free floating structure that is movable in the vertical direction due to a magnetic field generated between the magnetic shaft and a first magnetic element disposed in the housing that permits the screen set to be controllably and selectively moved in the vertical direction as the screen set rotates such that the influent stream is cleaned by passing through the screen set which results in creation of a first flow made up at least partially of the waste and which flows in one direction towards the at least one waste port and a second flow made up of the processed clean effluent stream that flows in another direction and is received within the discharge conduit where it is then withdrawn from the housing through the at least one outlet port.
