Claim:
A method for treating liquid manure, comprising the steps of: pumping liquid manure from a storage facility to a distribution chamber; delivering said liquid manure over a first vibrating screen, to partially separate solids from liquids; discharging retained material on said first screen to a storage container; discharging partially cleansed liquid through said first screen into a holding tank; pumping liquid from said holding tank to at least one cyclone separator; discharging a first stream from said cyclone separator, containing larger particles on to a second vibrating screen, to further separate solids from liquids, and delivering a second stream from said cyclone separator, comprising substantially cleansed liquid, to a trough; discharging a first steam of liquid from said trough to said holding tank, to form a loop treatment cycle; and discharging a second stream of liquid from said trough back to said storage facility.
