Horizontal shaft paddle wheel flocculators are to be used for flocculation in a water treatment plant with a design flow rate of 130 ML/d. flocculation is to be designed with two parallel trains and each train is to be made of five compartments in series. The total detention time (HRT) for flocculation is to be 25 minutes. The paddle wheel flocculators to be used will have the design shown below: Two such paddle wheels will be on the shaft in each stage (compartment) of flocculation. Make the following design decisions for the second compartment in each flocculation tank: Use 3 paddle boards
Horizontal shaft paddle wheel flocculators are to be used for flocculation in a water treatment plant with a design flow rate of 130 ML/d. flocculation is to be designed with two parallel trains and each train is to be made of five compartments in series. The total detention time (HRT) for flocculation is to be 25 minutes. The paddle wheel flocculators to be used will have the design shown below: Two such paddle wheels will be on the shaft in each stage (compartment) of flocculation. Make the following design decisions for the second compartment in each flocculation tank: Use 3 paddle boards per arm with leading edges located at 0.67, 1.33 and 2.0 m from the shaft centreline. The width of the paddle boards is 0.15 m. The dimensions of the compartment in the stage (including the number of paddle wheels and their lengths) The water power input required to achieve a G value of 30 s?1 and The rotational speed of the paddle shaft Design criteria for paddle wheel flocculator Parameter Unit Value Diameter of wheel m 3 ? 4 Paddle board section mm 100 ? 150 Paddle board length m 2 ? 3.5 A paddle boards/tank section area % < Cd L/W = 1 1.16 L/W = 5 1.20 L/W = 20 1.5 L/W 20 1.90 Paddle tip speed m/s Strong floc, 4 Weak floc, 2 Spacing between paddle wheels on the same shaft m 1 Clearance of paddle wheel from basin walls m 0.7 Minimum basin depth m 1 m greater than the diameter of paddle wheel Minimum clearance between stages m 1
