Optimisation of a bioscrubber system for treatment
of VOC emissions in a hazardous waste recycling
system under special focus on the fate of
2-butoxyethanol
VOCs within waste air streams and waste water batch
phases occurring in hazardous waste recycling procedures
should be biologically treated with a two-stage
bioscrubber-regenerator system. The composition of
waste compounds in both phases show high fluctuations.
However, main compounds like butyl acetate,
ethyl acetate, butanol, methyl ethyl ketone or 2-butoxyethanol
are present permanently. The goal of this
diploma thesis was the attendance of an on-site analytical
campaign for several weeks, firstly. Based on
these analytical data a synthetic waste air was defined
and degradation of this carbon mixture was tested and
optimised in half-technical scale. 2-butoxyethanol appeared
as most critical compound within this air, because
of its easy accumulation behaviour. Thus, the
discovery of the biological degradation pathway was
the content of further biochemical and genetical experiments.
