Design Of Mechanical Rapid Mix Unit
Flash Mixer
Rapid mixing is an operation by which the coagulant is rapidly and uniformly dispersed throughout the volume of water to create homogeneous system.
This helps in the formation of microflocs which results in proper utilization of chemical coagulant by preventing formation of hydroxides .
Designing of clariflocculator
The combined unit of flocculator and clarifier is known as clariflocculator.
It has two concentric tanks with inner tank serving as flocculation basin and outer tank serving as clarifier.
