Question: A filter was installed to separate suspended solids from a waste stream running at 5atm. The receiving deposited cake is expected to reach 50% moisture

A filter was installed to separate suspended solids from a waste

A filter was installed to separate suspended solids from a waste stream running at 5atm. The receiving deposited cake is expected to reach 50% moisture with dry solids density of 6.5g/cm3. If the particles equivalent diameter is approximatively 0.001mm and stream is running at 7000 kg/hr with 25% of insoluble solids, determine the following: (a) The specific resistance of the cake, if the ratio between the wet cake and dry cake is 2 , the density of water is 1000kg/m3 and the Kozeny's constant is 7.4. [10 marks] (b) The volume of filtrate collected in 1 hour. Given that Rf=0 and 1atm=101325Pa. [8 marks ] (c) Filtration capacity, if 200L water was used for washing. Given that water viscosity is 1mPa.s. [8 marks] (d) Time spent for one complete cycle. Given that an additional 15 minutes was given for discharge, cleaning, and assembly operations. [2 marks]
