Abstract
Abstract A method of treating animal wastes to reduce odors produced by the decomposition of the organic materials in the animal wastes. Contacogen particles, comprising solid catalyst particles having surface portions which are wetproofed by treatment with a hydrophobic material, are floated on the surface of a watery mass containing the animal wastes. The Contacogen particles promote the oxidation by air of the odoriferous compounds produced by the degenerative breakdown of the animal wastes. In addition, the Contacogen particles are self-renewing in that a portion of them is continually at the air interface where the oxidation takes place. Livestock manure, human sewage, and the like may be treated in this manner wherever present in a contained, open air watery mass.
