The purification of protein has been widely used in the electrodialysis, ultrafiltration, microfiltration when comparing with the number of studies on the use of conventional membrane for different proteins’ separation [1~2]. But they were not used as a purpose of enhancing the permeability. The newly developed techniques superimpose additional forces such as the pressured hydraulic force. However, the principle disadvantage of this technique is that cannot be separated in high concentration of protein. In this paper a superimposed another force, that is, an electric field induces as a force on charged protein in order to reduce the surface layer on the membrane. A newly developed type by an electric force has been invented a electro-microfiltration membrane [3~5]. Present studies in this article are experimentally to test the performance of new-typed electro-microfiltration membrane at a low hydraulic pressure and induces high amount of permeates. As such, the membrane filtration was investigated based on the membrane properties measured experimentally using the cake filtration theory [6]. The microfiltration technique was chosen to reduce the transmembrane pressure (TMP) and to increase the permeate flux(see below figures). This study shows that this membrane system manufactured by a electro-microfiltration technique offers significant advantages. The
purification of protein in this presented work is to investigate in the membrane process under the influence of an electric field. This paper presents with example from membrane process showing how the filtration time is reduced by the use of an electric field. The transmembrane pressure (TMP) was reduced by 20 % as the electric field increased. The concentration of protein in the membrane process in the presence of an electric field was reduced by over 300 % in comparison with the membrane process without an electric field. The hydraulic electrofiltration provides an another substitute to the crossflow filtration in the purification of protein.
