ODOR EMISSION CAPACITY OF WASTEWATERS - STANDARDIZATION OF MEASUREMENT METHOD AND APPLICATION

Odorous emissions from sewer systems and wastewater treatment plants c an cause serious annoyance in the vicinity. Odorants which are present in a liquid phase are emitted into ambient air at the liquid-gaseous interface. The amount and the variation of emitted mass flow of odoran ts is significantly influenced by the amount of odorants which are pre sent in the liquid. Up to now, however, no measurement method was avai lable to describe this parameter, which can be called ''Odorants Emiss ion Capacity''. The paper describes a standardized method of determini ng the ''Odorants Emission Capacity'' and shows results and consequenc es from several case studies where this new method was applied.
