What is the specific flux of the system if it contains 75 sq. ft. of filter area and operates for 24 hours at a flow rate of 5 gpm? Assume that the water temperature is 20℃ and the TMP of the system is 20 psi.(a) 5.6 gfd/psi(b) 4.8 gfd/psi(c) 9.4 gfd/psi(d) 5.5 gfd/psiThe question was asked during an interview.My query is from Membrane Filter topic in portion Building Blocks of Dairy Processing of Dairy Engineering

Answer»

Right option is (b) 4.8 gfd/psi

The BEST I can EXPLAIN: We calculated the flux to be 96 gfd. In ORDER to CALCULATE specific flux, divide the flux by the TMP 96 gfd / 20 psi. = 4.8 gfd/psi.
