Overcash, M. AND F. Humenik. STATE OF THE ART: SWINE WASTE PRODUCTION AND PRETREATMENT PROCESSES. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-76/290 (NTIS PB267995), 1976.
Description:
A review of waste generation and pretreatment processes was compiled, expanded, and interpreted for the swine production industry. Typical swine units based upon waste management techniques were detailed as concrete slab facilities, slotted floorpit units, and swine drylot or pasture operations. Pretreatment processes for the production unit waste load were evaluated in relation to land as the terminal receiver and for waste conversion mechanisms affecting utilization processes. The pretreatment effects on waste constituents were examined for all forms of nitrogen, cations or salts, organics, microbial or pathogen content, and nuisance factors. The state-of-the-art report confirmed the large number of definitive studies on various pretreatment processes and the characterization of swine waste.
