Laminar Tube Flocculator
Introduction
In the flocculation process, suspended particles collide with each other to coagulate and transform into larger flocs, with the help of a coagulant, that can be removed by sedimentation. To improve the performance of flocculators, we need to research how the design and operational parameters affect the aggregation and settling velocity of the flocs. These parameters include energy dissipation rate, hydraulic residence time, coagulant dose, influent turbidity, etc. One of the goals for the AguaClara team is to develop a sedimentation tank that will form a fluidized floc blanket, which will help clean water as it flows into the sedimentation tank from the flocculator. To develop this floc blanket the flocculator must produce flocs that fall within a particular range of settling velocities. Our apparatus (flocculation residual turbidity analyzer or FReTA) is capable of measuring both settling velocity and residual turbidity under different flocculator operating conditions. Complete description and sketches of current apparatus setup can be found here.
