Seattle, WA 98112 The specific application to an existing manure maintenance system is thoroughly invest~gated. A review of popular and state-of-the-art literature indicated the benefits of: (1) high rate mixing through gas recirculation; (2) heat conservation through insulation and influent/effluent heat exchanger; and (.3) use of easily available and rehitively inexpensive manure storage tanks which . are sealed to form digesters. The economics of fertilizer enhancement are evaluated. · Methane R&D and Digester Tanks John H. Brinker, President A. 0. Smith-Harvestore Products, Inc. 550 W. Algonquin Rd.
