Effective harvesting of microalgae by coagulation–flotation

Nov 15, 2021Prior to the flotation process, the algal cultures were well mixed and subdivided into aliquots of 100 ml at a concentration of 0.5 g l −1, and transferred into the flotation cell. The batch flotation harvesting tests were conducted in triplicate with a batch run time of 15 min.

The flotation machine supplies a fluidizing action for the pulp by up and down recirculation of pulp. Pulp within the upper zone from the flotation cell is in fact brought down using the pulp recirculation well on the impeller, blended with air and also the pumped from the impeller to the cell developing the homogenous mixture inside the tank.

HydroFloat™ Series Dissolved Air Flotation (DAF) System

A well designed DAF treatment system will take up a relatively small plant foot print, and also lead to lower capital and operating costs. A dissolved air flotation (DAF) system resolves suspended solids and clarity issues by reintroducing a slip stream of treated water (from the system's effluent) back to the system's influent.
