A continuous rotary filter is required for an industrial process for the filtration of a suspension to produce 0.002 m3/s of filtrate operates with 20 per cent of its surface immersed in the slurry and drum rotate at 0.0166Hz. A sample was tested on a small laboratory filter of area 0.023 m² to which it was fed by means of a slurry pump to give filtrate at a constant rate of 0.0125 m3/s. The pressure difference across the test filter increased from 14 kN/m² after 300 s filtration to 28 kN/m² after 900 s. at which time the cake thickness had reached 38 mm. What are suitable area for the rotary filter, assuming that the resistance of the cloth used is one-half that on the test filter, and that the vacuum system is capable of maintaining a constant pressure difference of 70 kN/m² across the filter?
