es2inc.com/wp-content/uploads/2011/07/Chlorination-De...Feed forward systems use a flow signal representing plant flow at the chemical injection point and a chlorine residual signal measured upstream of the sulfur dioxide injection point. These signals are directed to a controller that proportions the feed rate of sulfur dioxide to the amount of residual chlorine to be removed from the water supply.

Here is an example of how to calculate the dose for your chemical feed pump to inject Fluorosilicic Acid. • Remember 1.0 ppm is the optimum level. • The natural level in our well is 0.3 ppm. • 1ppm - 0.3ppm = 0.7ppm. This means we need to set our pump to inject 0.7 ppm. • In this example our well pumps 600 gallons per minute. File Size: 18KBPage Count: 2

SizingChemicalFeedPump.pdfIn the example above, our "required feed rate" is 0.41 gpd. This feed rate is closer to 1-1.5 gpd for 3 gpd pump vs. the 3-5 gpd of 10gpd pump. Therefore we would choose the 3 gpd pump based on this calculation. However, as indicated we need to run between 1-1.5 gpd to maximize efficiency and were only at 0.41 gpd, therefore we will dilute ... File Size: 153KBPage Count: 2
