Odour annoyances are considered a major cause of public complaints to regulatory agencies regarding air quality and represent a growing social problem, especially in industrialized countries. In view of the need to diagnose odour sources for control and mitigation of possible impacts on communities, was assessed, through a case study, the odorous emissions from an open biofilter. The equipment was responsible for gas treatment generated in the wastewater plant treatment of a textile industry. Sampling was conducted in the inlet duct of the biofilter using direct sampling and on the emission surface (output) using a hood (VDI 3477:2004). Samples were stored in plastic bags manufactured in polyvinyl fluoride (Tedlar®) and transported to the laboratory, where the odour concentration (in UO m-3) was determined based on the dynamic olfactometry dilution procedure (EN 13725:2003). To calculate the odour emission rate (OER) (in UO h-1), the volumetric flow rate (in m3 h-1) was measured in the inlet duct of the biofilter. The values obtained for the efficiency and the OER were 98.7 % and 0.34 x 106 UO h-1, respectively. Comparing the efficiency value with the criterion established by Article 12 of Resolution SEMA No 054:2006 (State of Paraná, Brazil), adopted as reference, the biofiltration system meets the minimum efficiency rating of 85 % required in removing odour.Downloads
