SDD components
The main components of the SDD include :
- A flow splitter used to evenly distribute the incoming flow and direct it towards the vortex drop shafts.
- Two vortex drop shafts designed to maximise the gravitational and centrifugal forces used for sediment and oil separation.
- An oil storage area including including a quick access port for inspection and maintenance from the ground level.
- A large sediment storage area located at the bottom of the unit. The configuration of the system greatly reduces the risk of pollutant oil wash out.
