The performance of a dialyzer in a hemodialysis device is strongly influenced by permeable membrane pores. Research on the influence of membrane pores on relative mass transfer is still limited. For this reason, a simulation was conducted to vary the influence of membrane pore diameter with sizes of 0.4 μm, 1 μm and 3 μm and varying inlet pressures of 80 mmHg, 100 mmHg, and 120 mmHg. The simulation was carried out aiming to determine the mass transfer, shear stress, Reynold’s number, and pressure drop using blood biofluid with a flow rate of 40 ml / min. The results showed that the greater the pore diameter and membrane entry pressure will cause the greater mass transfer that occurs. In testing with blood, the highest diffusion coefficient was obtained at a pore of 3 μm with an inlet pressure of 120 mmHg of 3,37 x 10-7 m3 / s, and the smallest diffusion coefficient at a pore of 0.4 μm with an inlet pressure of 80 mmHg of 4,15 x 10-8 m3 / s. For the shear stress characteristics found that the greater the pore and the inlet pressure, the greater the shear stress. In the test of pressure characteristics, it was found that the greater the pore and inlet pressure, the decrease in pressure passing through the membrane will be greaterIn the test of the flow characteristics, it was found that the larger the pore, the greater Reynold's number.
