COAGULATION AND FLOCCULATION CALCULATIONS
Calculations are performed during operation of the coagulation and flocculation unit processes to determine chamber or basin volume, chemical feed calibration, chemical feeder settings, and detention time.
CHAMBER AND BASIN VOLUME CALCULATIONS
To determine the volume of a square or rectangular chamber or basin, we use:
Volume (cu ft) = length (ft) x width (ft) x depth (ft)
Volume (gal) = length (ft) x width (ft) x depth (ft) x 7.48 gal/cu ft
A flash mix chamber is 4 ft square with water to a depth of 3 ft. What is the volume of water (in gallons) in the chamber?
Referring to Equation
Volume (gal) = 4 ft x 4 ft x 3 ft x 7.48 gal/cu ft
= 359 gal
