The Control of Industrial Odours
Manager, Safety and Environmental Control Unit, Beecham Pharmaceuticals
Odour nuisance presents one of the most difficult technical problems in the field of pollution control, requiring complete removal of very low levels of contaminant.
Measurement of odour invariably involves a considerable degree of human judgement. Where appropriate, a chemical assay technique may be combined with a method of concentrating odour, to give a comparison of odour sources. However, a subjective method of odour assessment may well be necessary, in which case dynamic dilution sampling is the most reliable.
Technical methods of odour control are still in the course of development, although a wide range of methods is already available for consideration. Many control techniques bring further environmental problems of their own, such as the generation of a liquid effluent stream. However, a number of methods, such as ozone treatment, present the possibility of odour control without undesirable side effects.
