General Odour Control Measures in Sewage Treatment Works
- Dosing of chemicals at upstream sewage pumping stations to suppress odour generation from sewage
- Covering up of the source of odour, e.g. inlet works, primary sedimentation tanks and sludge treatment facilities to suppress odour emission
- Installation of deodourising units to clean up the collected foul air
- Dosing of chemicals at sludge treatment facilities to suppress odour generation from sludge
Caverns as Natural Barriers
The feasibility study will include a preliminary odour impact assessment for the relocated SKSTW. The assessment will determine the suitable ventilation shaft locations so as to mitigate the odour impact to the nearby community to meet the requirement of relevant standards
