sludge blanket clarification – Pulsator
Pulsed sludge blanket clarifier including flocculation

The Pulsator® is a pulsed sludge blanket clarifier. The sludge formed during flocculation is made up of an expansion mass. Water, that has coagulated beforehand, arrives from the bottom of the device and flows through this sludge blanket to emerge clarified at the top of the settling tank. The sludge bed is kept in expansion with the help of pulsating operation.
