Activated biofilm removal of low concentrations of toluene
ABSTRACT: A two‐step technique is presented for the biodegradation or transformation of low concentrations of benzene, ethylbenzene, toluene, and xylene (BETX) hydrocarbons. Step 1 incorporates the batch growth and attachment of a lush biofilm onto plastic surfaces utilizing a preselected substrate capable of stimulating desired biological activity. Step 2 involves continuous upflow biodegradation of low concentration levels of target organics by the generated biofilm. Step 1‐generated biofilms are predicted to deteriorate during protracted time periods, however, extended experimental runs on the order of four months were conducted with continued bioremovals. Target organic removals during Step 2 operations, quantified by a first‐order removal constant, are shown to be linked to Step 1 operating methodology.
