Abstract
The technical and economic feasibility was determined of treating dairy waste in a liquid state by a tandem thermophilic-mesophilic aerobic stabilization process, more commonly described as liquid composting. Experimental apparatus were set up at an operating dairy. A large fraction of dairy manure is relatively resistant to rapid biological degradation even at thermophilic temperatures. Antithetical requirements of sufficient oxygen for maximum biological activity and minimum air flow to preclude the need for an external heat source could not be satisfied with the particular experimental apparatus when utilizing air as the oxygen source. Improved results were obtained with an oxygen-enriched air supply which pointed out the potential advantage of a pure oxygen system. Preliminary cost estimates for a liquid composting process to serve 500 cows were developed within the context of current dairy operation economics.
