Odour generation and its release into the atmosphere is becoming of increasing importance to many effluent treatment plants. In addition to the general sense of environmental responsibility, in many areas, odour complaints can constitute a statutory nuisance and lead to costly disciplinary action by the local authorities.
Most odours at effluent treatment plants are generated by one of two processes:
The latter is most common and is usually associated with the metabolism of sulphur containing compounds producing mercaptans and hydrogen sulphide, or nitrogen containing compounds that generate amines. Aqua Enviro have a great deal of experience in the abatement of odour issues and are able to attend site to complete surveys focused on identifying the key areas of site which possess the greatest potential for odour generation. Once completed a suitable odour abatement strategy can be developed and managed on site to:
Aqua Enviro were recently commissioned to carry out a sulphur audit across the sludge streams of a 1 million PE WwTW’s. This identified a number of key bottlenecks where excessive sludge retention times were causing sulphur release – A number of simple pumping set-point changes based upon the project findings resulted in a net saving of >£250k per year through:
