Abstract: The present invention relates to a method for treatment of liquid or semi-liquid animal waste using porosive particulate matter to remove malodorous materials, and to an organic fertilizer composition comprising organic substances derived from animal waste, said organic substance being held in pores of porosive, nutritionally inert particulate matter.
Abstract: A method for cleaning thin gauge metal foil strip material using a plurality of wiper (12, 16, 20) and solvent application (14, 18) stages. The solvent used in the solvent application stages is an aliphatic petroleum type which is applied using low pressure to avoid atomization or separation of solvent components. The wipers of a first wiping station are made of a solid bar of polymer impregnated fiber material. The wipers of the second wiping station are spaced apart blades of urethane-based elastomer material.
