Scientists have developed a system to help identify noxious smells emanating from sewage treatment plants. The system, called the Smell Identification System (SIS), is based on an algorithm that identifies odors by analyzing data collected at wastewater plants and other facilities. The scientists take samples of the odours, categorise them according to the wheel and return them to the lab where they can be analysed to help find ways to neutralise them.
Scientists have developed a system to help identify noxious smells emanating from sewage treatment plants. The odour wheel, which will be presented at the National Meeting & Exposition of the American Chemical Society, has descriptions of odours that are easily understood by the general public, alongside details of the chemicals causing the smells. The scientists take samples of the odours, categorise them according to the wheel and return them to the lab where they can be analysed to help find ways to neutralise them.
