• You are asked to design a single media filtration system for a drinking water facility. The design flow rate is 20 mg/d (million gallons per day). The ideal filter velocity for your system is 8 m/hr. You design a set of filters to be used in parallel. Each filter box has a surface area of 50 m² .
•  a. How many filters do you need to construct? 
• b. Estimate the (clean-filter) head loss in kPa?
• c. What mass removal (filter efficiency) would you expect for an influent stream that contains equal parts (by mass) of 1, 10 and 100 um particles? You can assume an adhesion efficiency α = 0.7.
