CTP environment implemented a complete bypass of the site's high-quality water production. This production used river water and storm water as a feedstock. Once produced, it supplies the potable and demineralised water chain production of the site. Continuity and uninterrupted service is a necessity for the site.
The mobile system set up included:
- Raw water storage
- Physical-chemical treatment of the water at a flow rate of 100m3/h:
- On-line pH control
- On-line coagulation
- On-line media filtration
- On-line disinfection
- On-line polishing filtration
- Buffer storage of produced water, vital in the prevention of variations in site quality water requirement and unforeseen events.
- 2x8 shift operation to ensure continuity of production
This temporary treatment plant recorded the following performances:
- pH control between 7.5 and 8.5
- TSS removal: turbidity < 5 NTU
- Control of algae/bacteria proliferation: free chlorine maintained between 1 & 2 mg/l at all time
This turnkey solution allowed the maintenance of the site's water storage tanks and valves within the planned duration (2 weeks) without any disruption of the site water supply.
