5) In an ultra filtration process, the feed, whose composition properties are given below, is intended to be concentrated by protein in a polyethersulfone membrane with a pore size of 30 kDa. Time versus mass data obtained in this process are given in the table below. Using this data; a. Plot the permeate flux (kg/m2 hour) versus time (hours). b. Please give brief information about the pollution mechanisms that occur by examining this graph. c. Establish mass balance for each component. Calculate the mass (g) of each component in the feed, permeate and retentate flows. If there are losses in the system, consider the possible causes of these losses in a scientific way, considering the contamination mechanisms. d. Calculate the WRF value.
