Odour Emission Capacity  Sampling is an essential and extremely important sub-step in the whole measurement procedure, and can be the most relevant cause for measurement errors. Thus, sampling must strictly follow appropriate standards suited for the respective measurement task.

  sesion05 garces00The size and location of the sewage water treatment plant La Farfana, in Santiago de Chile, has implied different requirements in terms of monitoring gas odorant and odour, both inside the plant and in its populated environment. The aim of this work is to present the various gas and odour monitoring systems, measured at the emission sources, as in the places in which receptors are found.

Since the plant started its operation in 2003 various systems of monitoring, such as field panels, have been used with participation of neighbours and public officials; panels with specialized monitors; filling out of cards by passive monitors (neighbours); continuous monitoring, 24 hours a day, 7 days a week; odorant gas measurement; modelling of the dispersion of these gases, neighbour complaint phone reception system; campaigns of dynamic olfactometry, roundtables of ongoing work between the company and local communities, etc.

sesion02 mcginley00 A sewer District in the Southwest of U.S.A. operates a 30 MGD design average flow Activated Sludge and Tertiary Treatment facility (Facility). In 2007 an exploratory odour study was conducted to concentrate on three problem areas (pre-treatment, digesters, and sludge dewatering) to reduce odour emissions in a cost-effective manner.
