BUELNA, G.; TURGEON, N. e DUBE, R.. Organic Bed Biofiltration: A new Technology for Simultaneously Deodorization of Liquid and Gaseous Effluents on Pig Farms. Ing. invest. y tecnol. [online]. 2007, vol.8, n.1, pp. 1-9. ISSN 1405-7743.
The growth of pig industry has caused a great problem of undesirable odours, particularly in and around production buildings, storage areas and when the pig manure is spread. Among manure treatment options, organic bed biofiltration represents a very promising technique for the deodorization and treatment of pig manure. Research and development work to optimize the BIOSORTM-Manure, a biofiltration process for simultaneously treatment of liquid and gaseous effluents on pig farms, have been realized on the site of a piggery (Île d'Orléans, Québec,Canada) using a 560 m3 biofiltration system. The results obtained show that the BIOSORTM-Manure process is an efficient, simple and performing technology bringing a global solution to odours pig manure problems. Actually, the process reduce over 95% the polluting load from the gas of the pig farm (NH3, H2S), the BIOSORTM-Manure process eliminates over 80% the odour intensity coming from the production installations, the storage, the transportation and the spread ing of the manure.
