Abstract
Hydrocarbons emissions were measured from an aeration tank of a municipal wastewater treatment pilot plant. The collected off-gas samples were characterised for C_2–C_7 hydrocarbons using GC-FID analytical technique while the total volatile organic compounds (TVOC) were measured using a continuous hydrocarbon gas analyser. Approximately, the estimated emission rates for 1 m^3 of wastewater from this aeration tank were 5 mgC of C_2–C_7hydrocarbons, and an average of 7 gC of TVOC. With exception to toluene, all other measured hydrocarbons are emitted less than 1 mgC day^-1. The results support the view that a significant reduction in annual emissions of hydrocarbons from wastewater treatment plants in Vienna has taken place.
