Development and operation of a trickling biofilter system for continuous treatment of gas-phase trichloroethylene

Biotechnol Lett. 2003 Oct;25(20):1757-61. doi: 10.1023/a:1026087928877.

Abstract

A parallel trickling biofilter (TBF) system that consists of two TBFs units in parallel, one for biodegradation of trichloroethylene (TCE) and the other for reactivation of an inactivated biofilm, was developed and operated for continuous treatment of gas-phase TCE by Burkholderia cepacia G4. For inlet loadings below 8.6 mg TCE l(-1) d(-1) complete removal of TCE was achieved. The maximal TCE elimination capacity was 17 mg l(-1) d(-1).
