Slide 8:

A water treatment operator is adding a dose of 2mg/l chlorine to a plant flow of 4MGD. How many lbs/day of chlorine will the plant use and what is the chlorine demand of the water if there is a measured residual of 1.7mg/l in the finished water? Consider this dosage problem

Math Made Easy Steps:

Math Made Easy S teps Step 1: Draw a picture Step 2 : Write down the formula Lbs/day = Flow (MGD) x conc.(mg/l) x 8.34lbs/ga l Step 3 : Plug in the known values Lbs/day = 4MGD x 2mg/l x 8.34lb/gal Step 4 : Multiply across bottom of the Davidson Pi Formula 66.7 lbs Step 5 : Dose = Demand + Residual 2mg/l – 1.7mg/l = 0.3mg/l For more details on easy dosage calculation methods click here . 4 X 2 X 8.34
