The main source of smells are produced in the purification process of wastewater. The main characteristics of the emissions of the different elements of the wastewater treatment plant are its high offensive smell, their flow is relatively low but their hedonic tone is very unpleasant.
ALSAT has carried out a series of actions to improve the water purification process and at the same time reduce odour emissions from the purification plant.
The main object of this project has been to confine the emissions from the biological reactor to extract them from this unit and be able to purify them before they are released to the atmosphere. The biological reactor has been covered with a special PVDF treated cover in order to achieve this.
Once covered, the extraction system was installed to eliminate the odours.
