Flocculation / Sedimentation Tanks

Pulsair remains dedicated to lowering energy costs with an efficient, “non-shear” mixing process that outperforms mechanical and impeller mixers.

Flocculation / Sedimentation (Drinking Water Treatment)

One of the common individual steps in removing contaminants from drinking water is the flocculation process. During this process synthetic organic polymers, iron salts and alum are used to promote coagulation that helps combine particles into larger ones, which then settle out as sediment. With shear-sensitive materials like “floc”, Pulsair mixers outperform mechanical and impeller mixers due to the “no shear” nature of the Pulsair process.

Benefits of Pulsair’s wastewater mixing systems for flocculation / sedimentation tanks:

No shear – gentle bubble mixing does not cause any shear
Energy savings – due to sequential injection of air our systems use less energy
Programmable Operations – Programmable control options allow a facility to manage mixing functions in multiple tanks from a single point
No moving parts inside the tank – Eliminates the maintenance costs commonly associated with mechanical mixers
No pumps or motors to maintain
Simple installation – no baffles are required, and in some cases, tanks can be retrofitted without taking them out of service
Reduces overall operational and maintenance costs
