Development of the Odormat for Sewage Odour Measurement

Development of the Odormat for Sewage Odour Measurement

With today’s increasing levels of development, residential areas are inevitably built closer to odour generating facilities, such as sewage treatment and chemical industrial plants. Odour measurements, which provide important information in the planning of the plants and odour treatment facilities, are needed to underpin the numerous decisions that will have to be made to reduce odour nuisance. The use of dynamic olfactometry is widely regarded as a favoured sensory technique for quantifying odour. In recent years, emphasis has been directed towards standardizing equipment and techniques of odour sampling and measurement so that results can be compared between laboratories and between different olfactometers with some degree of reliability. This paper describes the development of a computerized olfactometer for sewage odour measurement in Singapore.
