Dissolved Air Flotation
The Poseidon PPM and Saturn clarifiers brought to the paper industry the new lamella DAF concept. Thanks to their optimized and patented design which result in both better water quality and reduced chemical consumption, the Poseidon clarifiers have a leading position in the market. 
Working Principle
Filtrate to be clarified is mixed with very small air bubbles, a flocculent and in some cases a coagulant. The chemicals enable the collection of almost all suspended solids into flocs. The presence of air bubbles in the flocs provides them with a density below 1 and enables them to reach the surface.
The numerous separation plates or cones (lamella) provide a very high separation surface, which results in excellent water quality and significantly reduced chemical consumption.
Applications
The POSEIDON PPM Clarifier and SATURN Clarifier provide cost efficient water treatment for:
- Mill effluent
- Fibre recovery (Saveall)
- Deinking Greywater
- Micro Stickies and Wax Removal
- Filtrate Polishing
Benefits
Operation
- High TSS capture rate (generally over 95%)
- The highest sludge consistency (up to 12%)
- High water yield (up to 98%)
- Easily handles upstream variations in flow rate and feed concentration
- The Modular design of the Saturn allows future capacity increases.- Significant polymer savings
- Extremely reliable air mixing system, with the patented Poseipump, allowing optimal calibration of the bubble size
- No plugging risks
Installation 
- Low installation costs due to a modular and pre-assembled construction
- Extremely limited footprint
- Little or no field erection: unload, position and connect
Costs
- Low polymer consumption
- Minimal operator attention
- Complete stainless steel and corrosion proof construction
- Very limited maintenance
