10-1. Design a slow sand filter system for a community which has a projected popula- tion of 3000 and an average per capita usage of 300 L/day. Use the Goodrich formula of Chap. 2 to estimate the peak flow rates, and size the system so it can produce water at the maximum weekly rate with one unit out of service. The design filtration rate is 6 m/day.

The bed thickness of a speed sand filter is 1.3 m. A sand with a specific diameter of 0.8 mm and a specific gravity of 2600 kg / m3 will be used as filter material. The shape factor of the sand is 0.9 and the porosity of the clean bed is 0.45. The water layer thickness on the bed is 1.1 m. Average filtration speed is 130 m / day and maximum filtration speed is 180 m / day. The maximum flow rate is 24087 m3 / day and the kinematic viscosity of water is 1.01x10-6 m2 / sec. The maximum head loss in the filter is required to be 1.9 m and negative pressure is not allowed. a) Find the initial head loss of the filter bed. b) Find the required number of filters and the area of each filter in case 3 filters are in reserve. c) Calculate how many meters depth the pollution penetrates at the end of filtration.
