Technique
Description
Applicability
(a)
Minimise residence times
Minimise the residence time of waste water and sludge in collection and storage systems, in particular under anaerobic conditions.
Applicability may be restricted in the case of existing collection and storage systems.
(b)
Chemical treatment
Use chemicals to destroy or to reduce the formation of odorous compounds (e.g. oxidation or precipitation of hydrogen sulphide).
Generally applicable.
(c)
Optimise aerobic treatment
This can include:
(i) controlling the oxygen content;
(ii) frequent maintenance of the aeration system;
(iii) use of pure oxygen;
(iv) removal of scum in tanks.
Generally applicable.
(d)
Enclosure
Cover or enclose facilities for collecting and treating waste water and sludge to collect the odorous waste gas for further treatment.
Generally applicable.
(e)
End-of-pipe treatment
This can include:
(i) biological treatment;
(ii) thermal oxidation.
Biological treatment is only applicable to compounds that are easily soluble in water and readily bioeliminable.
