AquaDAF Water Clarifier Advantages
Flexible & Robust : •
treats water with temperature >3
C
•
best solution for low turbidity / high algae raw water
•
adapts to occasional peaks of TSS or Turbidity upto 200 NTU.
°
Cost effective : •
Reduction in the time required for the response to 5 min
•
Decrease the size of footprint while retaining its performance.
Easy to operate : •
Easy to operate and maintain (very few mechanicals, no lamella modules, no clogging)
•
