Summary

Biotrickling filters (BTF) or trickling biofilters have been developed as an efficient alternative to conventional biofilters for specific applications. They are more suitable than the latter for the removal of pollutants generating acid end-products, such as halogenated or sulphur bearing pollutants. The recent optimization of BTF allows the use of compact bioreactors treating high pollutants loads at relatively low Empty Bed Residence Times. Some parameters that have recently been evaluated and optimized include, among others, the gas and liquid velocities and the characteristics of the packing materials as well as techniques for the removal of excess biomass and other solid compounds (such as elemental sulphur) affecting pressure drop. The major characteristics and operating strategies of full-scale BTF are described.
