Lamellar Clarification

Pulsatube is a lamellar clarifier with a pulsed sludge blanket, and can perform coagulation, flocculation andclarification in a single unit.Its unique design means that the quality of clarified water is perfect, regardless of variations in quality and flow of the raw water.

The sludge formed by flocculation is an expanding mass (sludge blanket), the homogeneity of which is maintained by pulse cycles, applied by a vacuum chamber.The water that has coagulated beforehand flows regularly and evenly from the bottom to top through this sludge blanket and returns clarified to the top of the settling tank. The lamellar modules in the clean water area above the sludge blanket also optimize the settling rate.Pulsatbe is easy to use thanks to overlay of the flocculation (in the sludge blanket) and clarification areas in a single unit. Furthermore, the minimal energy consumption (~ 5kWh/m3), the reduced water leakage and the Very low polymer dosage allows to preserve the environment.
