A plant expansion is planned for Urbana. The new design flow rate is 1.0 m/s. A deep bed mono-media filter with a design loading rate of 600 m dmof filter is to be used. If each filter box is limited to 50 mof surface area, how many filter boxes will be required? Check the design loading with one filter box out of service. Propose an alternative design if the design loading rate is exceeded with one filter box out of service.
