Question:
Flocculation Tank Design Parameters
Two parallel tanks (see plant layout)
Two staged taper floc
G1 = 40 s-1
G2 = 15 s-1
Paddle Design (see Figure 2)
4 arms
2 paddles/arm
Distance from shaft to center-line of the inside paddle is 3.0 feet
Distance from shaft to center-line of outside paddle is 5.5 feet
Paddle Length = 12 feet
Paddle Width = 6 inches
Flocculation Tank Dimensions
Width = 20 ft
Length = 26 ft (Each stage is 13ft in length)
Depth = 13 ft
a)What is the rotational speed of the paddles in the second compartment? Assume Cd = 1.6.
(b)Does the peripheral speed of the outside paddle in the second compartment fall within typical design requirements?
