Abstract ▼ AI-Helper

The present study was to investigate the purification of a fermentation broth by an electromicrofiltration membrane. Microfiltration runs with a crude and a centrifuged broth, with solution of particles recovered from centrifugation and with permeates from microfiltration experiments were thus compared. Microfiltration performances were governed by colloids and small particles that induced sharp initial flux declines. For these results, the evolution of the overall membrane resistance was increased by $80\%$ in comparison with the electromicrofiltration membrane. The main focus of this study was set on the enhancement of the filtrate flux by an electric field. This pressure electrofiltration leads to a drastic improvement of the filtration by $100\%$ and the filtration time was thereby reduced. Pressure electrofiltration serves as an interesting alternative to the cross-flow filtration and it effectively separates advantageous constituents such as amino acids and biopolymers from a fermentation broth. They were equally maintained during the microelectrofiltration, although they were significantly reduced by $45\%$ by the microfiltration without the application of an electric field. Accordingly, since the electrofiltration membrane was provided more permeability, this study experimentally demonstrates that the permeability inside a membrane can be controlled using an electric field.

문제 정의

The new-typed electrofiltration indues high amount of permeates and makes the separation of biopolymers easier [10, 11]. The aim of the present work was to investigate how to overcome the fouling in the process by means of electro-microfiltration experiments performed on a crude fermentation broth from the brewing industry, in comparison with microfiltered runs performed with the same broth.

제안 방법

Dynamic filtration was used in order to reduce the fouling problem was used namely rotating disc filtration, which represents a further possibility for reducing the surface layer on the membrane in dead-end filtration [4-6]. In this study, a superimposed electric field induced a force on charged biopolymers in order to reduce the surface layer on the membrane. The use of an external electric field is a promising approach towards improving the permeate flux in cross- flow filtration [7-9].

성능/효과

5. As a result, the permeate velocities were increased by 60.0, 95.5, and 133.3% as the electric field was increased to 8, 15, and 24 Y respectively. This indicates that the permeate velocity increased according to the direction of the electric field and the amount of permeate also increased.
Third, the permeate velocities were increased by 60.0, 95.5, and 133.3% as the electric field was increased to 8, 15, and 24 Y respectively.
