Determination of the organic carbon <strong>and</strong> ammonia<br />
concentrations with quantification of odorous<br />
components in exhaust gas of a sewage sludge<br />
drying system<br />
In many operating conditions, emissions of a belt dryer<br />
were quantified in drying procedure of mechanically<br />
dewatered sewage sludge, <strong>and</strong> purification capacity<br />
of the connected exhaust gas treatment system (scrubber/biofilter<br />
combination) was quantified as well.<br />
Two portable FIDs <strong>and</strong> a quasi-continuous measuring<br />
NDIR gas photometer were applied <strong>for</strong> it. Besides, gas<br />
samples were adsorbed on Tenax, <strong>and</strong> analysed <strong>for</strong> relevant,<br />
odorous exhaust gas constituents by means of<br />
a GC/MS/FID-System in conjunction with an Olfactory-<br />
Detection-Port (ODP).<br />

Determination of emission potential of oil separator-waste<br />
water by total stripping with GC/<br />
MS-GC/FID analysis<br />
The determination of emission potential of waste water<br />
was per<strong>for</strong>med according to ATV-Merkblatt A 204<br />
in the way of total stripping. All volatile organic compounds<br />
are converted into gas phase by injecting an<br />
inert gas at high temperature. The components are<br />
then enriched by adsorption on Tenax®; <strong>and</strong> gas chromatographically<br />
determined after thermal desorption<br />
<strong>and</strong> sampling.<br />
