Aquadaf Package System (PS) is a range of compact metal units incorporating the following treatment stages:
- Coagulation of colloidal matter
- Hydraulic flocculation using baffles
- Rictor technology rapid dissolved air flotation
- Discharge of sludge accumulated on the surface by overflow or scraping.
This range covers flow rates from 25 to 300 m3/hr.
The dissolved air flotation technology used in the Aquadaf Package System is identical to the technology implemented in conventional Degrémont high capacity flotation plants:
- Aquadaf: surface water clarification for drinking water production
- Seadaf: seawater clarification before desalination
- Greendaf: tertiary phosphorus removal from urban wastewater
This flotation technology is particularly effective in eliminating low density particulate pollution (algae, difficult-to-settle suspended solids). High flotation speeds make this a particularly compact clarification solution.
The main areas of application of Aquadaf PS are as follows:
- Surface water, brackish water and seawater clarification
- Tertiary treatment of wastewater and conditioning for reuse
- Pretreatment in membrane systems
