Ambient air drying of sludge

Abstract

A system for reducing moisture content of a wet waste product includes a drying surface; a dispenser that deposits the wet waste product onto the drying surface; an air moving device (AMD) that induces a flow of ambient air over the wet waste product on the drying surface to produce a dried waste product from the wet waste product; a collection area that transports the dried waste product away from the drying surface; and an agitator that moves the dried waste product from the drying surface to the collection area after the dried waste product has been dried to have a predetermined moisture content. A corresponding method for reducing moisture content of the wet waste product comprises using the system to convectively dry the wet waste product to produce the dry waste product. The wet waste product can be from a swine lagoon.
