Calculate the backwash pump required for the activated carbon filter for the following details. Flow: 1000 m3/h. Rise Velocity: 15m/h

Calculate the backwash pump required for the activated carbon filter for the following details. Flow: 1000 m3/h. Rise Velocity: 15m/h Correct Answer 1608 m3/hr

The area of the filter is calculated based on the flow rate and the rise velocity. Area of the filter is calculated as Flow/ Rise Velocity. Area= 1000/15 =67 m2. Backwash pump velocity is considered as 24 m/hr. Therefore the backwash pump required is area x velocity = 67 x 24= 1608 m3/hr.

A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
