Odours, consisting often of mixtures of components, are produced in a variety of industries such as sewage treatment, animal carcass rendering, food processing and animal feed manufacture. These mixtures may contain both acidic components (hydrogen sulphide, mercaptans, phenols, aldehydes, fatty acids) and basic compounds (ammonia, amines), and may be effectively treated by washing with both acidic and alkaline solutions of hydrogen peroxide. This method of treatment avoids imparting odours to the cleaned gas, which is possible with some other oxidants.
Hydrogen peroxide is not always the complete answer to all such problems, since considerations of scale, capital and running costs may render it less attractive economically or practically than other processes. Where applicable the use of hydrogen peroxide does afford significant benefits, particularly in producing clean processes with effluents that are reusable or that may be disposed of without damage to the environment.
Its use should be investigated as a matter of course whenever the need arises for gaseous effluent treatment, since even though it may not improve the absorption process itself, and in a number of cases it does, clean oxidation or reduction of the liquid effluent may be beneficial.
