The flocculation basin is to be divided into 3 sections of equal volume, each section having constant velocity gradients of 50, 35, 25 s-1, respectively. The total flocculation time is to be 21 min and the water temperature is 15 °C. The timber baffles have a roughness coefficient of 0.3. A common wall is shared between the flocculation
Lesson 15: Coagulation and Flocculation Calculations
The term coagulation refers to the series of chemical and mechanical operations by which coagulants are applied and made effective. Flocculation follows coagulation in the conventional system and is the physical process of slowly mixing the coagulated water to increase the probability of particle collision.

It is an essential operation designed to agitate force in fluid and coagulation. The design criteria of the flocculation tank are based on previous studies [2, 19]: Q = 41.64 m 3 /min t = 30...

Below are design approaches for several of the different potential flocculator geometries. In all cases we will need equations relating head loss, velocity gradient, viscosity, and collision potential. Flocculators must operate effectively over a range of temperatures and the critical design temperature is the coldest operating temperature.
A cross-flow, horizontal shaft, paddle wheel flocculation basin is to be designed for a flow of 25,000m3/d, a mean velocity gradient of 26.7/sec (at 10°C), and a detention time of 45 minutes. The GT value should be from 50,000 to 100,000. Tapered flocculation is to be provided, and the three compartments of equal depth in series are to be used.
Flocculation: Flocculation is a slow mixing process in which destabilized colloidal particles are brought into intimate contact in order to promote their agglomeration . The rate of agglomeration or flocculation is dependent upon the number of particles present, the relative volume which they occupy, and the velocity gradient (G) in the basin. The

accentuate tapered flocculation. The sedimentation tank is a rectangular horizontal flow tank of effective capacity 4.2 m 3, giving a nominal reten-tion time of 2h 20min. Tube settlers fill the tank and are of 50mm o.d. PVC and 1.15 m in length, inclined at an angle of 60° to the horizontal and arranged in an array of 25 over
