Flocculation is a process of gentle mixing of water / wastewater to
agglomerate and form larger composite particles, flocs. Flocculation
process is generally follows coagulation process. Different size and
type of flocs are formed depending upon the intensity of mixing and the
power dissipated in the water. The size and type of flocs required depends
on the process that follows flocculation i.e. floatation, settling or
filtration. The efficiency of removal of solid and other impurities that
follows flocculation process is increased if the raw feed is properly
flocculated. A well-designed flocculator provides good flocculation and
years of trouble-free operation.
Napier Reid is a leading designer and manufacturer of high quality, efficient
design flocculators. Various factors like floc type and size required,
velocity gradient, impeller tip speed, shear, ratio of impeller diameter to
equivalent tank diameter, superficial velocity and viscosity is considered
while designing the flocculators.
The type of flocculators manufactured by Napier Reid includes the following:
