About the Project
Tuosist Water Treatment is supplied from a lake source. The treatment plant is designed to produce potable water at a flow rate of 16m3/hr over 24 hours. The treatment system comprises ozonation, filtration and UV radiation of raw lake water, the treated water flows to the existing reservoir. Backwash water is stored in a backwash holding tank.
The EPS designed plant comprises lake water pumping, ozone followed by sand filtration, GAC filters and UV. The treated water gravitates to the existing reservoir.
The process comprises of the following principal items:
- 2 raw water pumps
- 3 pressure filter units
- 2 RGF backwash pumps
- 1 dirty wash water holding tank
- 1 supernatant pump
- 1 IBC chemical storage tanks
- 1 ozone system.
The flow rate to be treated by the new water treatment plant is set at the front end of the plant. It is fully selectable via the HMI system in the range of 0 – 384 m3/day. The new raw water pumps located in the existing intake pump sump will ramp up or down to achieve the set point flow rate.
The two new intake pumps operate on a duty/standby basis. The intake pumps will pump flows forward to the balance tank at the water treatment plant. The water flows by gravity through the whole treatment plant to the existing reservoir.
