Resumen de Deodorization of pig manure by organic bed biofiltration
Gerardo Buelna, Nicolás Turgeon, R. Dubé
The growth of pig industry has caused a greater problem of undesirable odours, particularly in and around production buildings, storage areas and when the pig manure is spread. By measuring the intensity and duration of odour emissions, it was established that the sources of odour in Québec were at 20% for buildings, 10% for storage, 5% for recovery and 65% for spreading.
Increasingly stringent standards and heightened public awareness regarding environmental issues, has led to an increase in research on various treatment methods used in different countries. 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, in reducing 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 spreading of the manure.
