ABSTRACT:
Dry and liquid feed supplements are recovered from treating animal wastes collected from a confinement feeding area for livestock and the like by a closed loop type of collection system including a primary liquid storage tank. Solids and liquids are separated from the collected wastes by dynamic liquid filtering apparatus including a unique compression filter. Liquid is withdrawn near the surface of the primary tank, passed through a second solid/liquid separating filter and transferred to a secondary tank. Preferably rarified oxygen is forced into both tanks so as to aerate the liquids. After appropriate aerobic digestion or oxidation, the secondary tank liquids are used to supplement feed water and the solids are used to supplement dry feed ration.
