lamellar settling with pulsed sludge blanket – Pulsatube™

lamellar settling with pulsed sludge blanket – Pulsatube
A clarifier combining the benefits of sludge contact, sludge blanket pulsation, and lamellar settling

The Pulsatube™ is a Pulsator in which lamellar modules have been added, doubling its speed. The Pulsatube™ can perform flocculation and clarification in a single unit.

The sludge blanket, located in the lower part of the settler, is animated with alternating vertical motions. This is why we talk about « pulsed » sludge blanket.
