The largest pores in microfiltration membrane are filled with mercury, when the pressure becomes ________ Lowest Highest Zero Moderate

Inorganic membrane has applied Pressure up to ________ 10 bar 20 bar Both (a) and (b) None of the above

Bubble point method, is used to measure the _________in a given membrane. Smallest active pores largest active pores Both (a) and (b) None of these

Which of the following statements is incorrect? Porous membrane contains fixed pores, in the range of 0.1-10 µm for microfiltration and 2- 100 µm for ultrafiltration. Porous membrane contains variable pores, in the range of 0.1-100 µm for microfiltration and 2- 100 µm for ultrafiltration. The main problem in microfiltration and ultrafiltration membrane is flux decline. Therefore, the choice of membrane material for such process is based on prevention of fouling and cleaning procedure after it is fouled. none of the above
