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)

• No need to add material to weigh down the

flocs.

• Instantaneous Start and Stop.
