Design the first compartment of a cross-flow paddle flocculator for the city of Nonesuch by determining the basin dimensions, the paddle configuration, the power requirement, motor power, and rotational speeds for the following parameters:

Design flow rate = 36×10³ m³/d

t = 23 min

Three flocculator compartments with G = 40, 30, 20 s^–1

For each compartment L = W

Water temperature = 10^oC

Assume the design recommendations in Table 3-7 apply

To complete the design, provide a dimensioned sketch of the basin and wheels.

Hint: for a first trial assume a wheel diameter of 3.5 m.
