A Batik factory is soon to be opened somewhere in Kuala Terengganu. As a chemical engineer, you have been assigned to design a membrane module to process a dye solution. An asymmetric ultrafiltration membrane is chosen for separating dyes from a liquid stream in order to achieve a more concentrated dye-water mixture that will be reused to dye fabric. The feed waste stream arrives at a flow rate of 2.2 m3 with concentration of 1.2 kg/m? The membrane's operating characteristic was calculated from various experiments and found to be as follows Jo = 0.04 In (15) where is the bulk concentration C (kg/m) and Jy in flux in m/(.m?). If the area of the membrane module is given as 25 m2. Assume almost-complete solute retention, a) determine the retentate dye concentration and the permeate flowrate from the membrane module. [3 marks] You decided to improve the filtration by adding another membrane module of same area in series
