<p>TITLE OF THE INVENTION Controlled Sludge Composting System The invention is a controlled system for composting sludge to a useable state. The method of the system eliminates the usual objectionable odors. The system consists of a thorough mixing of the sludge with carbonaceous material, layering the mixture in a silo and moving it through the silo on a timed interval basis, forcing air through the mixture in the silo to promote the composting action by an aerobic bacteria process, periodically withdrawing the treated material in a manner compatible with the timed interval basis, further layering the composted material in a second silo having a forced air means to complete the treatment process, and withdrawing the final treated material for packaged or for bulk distribution to users.</p> |
