A non-compressible aqueous slurry has filtering characteristics such that K = 1.44 × 10-6 for Q in tonnes/cycle. If slurry is to be filtered at constant pressure in a plate and frame filter press at a rate to process an average of 1 tonne per hour of feed and it is to be washed with an equal amount of water equal to on-eighth the volume of filtrate, The dumping and assembling time is 6 hrs. The plant operates 6000 hrs/yr and the slurry feed contains 12% wt solids and the cake contains 72% solids. Annual fixed cost may be taken as Rs. 20/m² of filtering area. Direct cost is Rs. 4.33/m² Cleaning cost is Rs. 8.12 /m² of filtering area. What is the minimum annual total cost and the optimum cycle time?
