Abstract

PURPOSE:To prevent liquid in filtration from being directly brought into contact with ceramic by coating the surface of porous ceramic with a synthetic resin soln. and then using the other solvent to remove the solvent incorporated in the soln. and fixing the synthetic resin thereon. CONSTITUTION:An alumina ceramic filter which is regulated to 2mum mean pore diameter and has 2.5mm thickness is fitted to a filter and a 10% polysulfone/dimethylformamide soln. stored in a raw liquid tank 2 is permeated via a peristaltic pump 3 and both surfaces of the ceramic filter are lightly wiped off and thereafter it is introduced into water and left wherein for 30sec and a polysulfone membrane is formed on the surface. Then in case of exchanging the liquid incorporated in the raw liquid tank 2 with water and making it permeate through the ceramic filter 1 by the pump 3, only dimethylformamide is dissolved in water and removed. Colon bacilli does not permeated this filter and bacteriophage and DNA are not adsorbed but allowed to permeate.

[Problem that the invention sought to solve] When the porous ceramic filter is used for purposes such as sterilization or pyrogen removal, it can be used in addition to filtration.
Although ceramics had high performance due to their high adsorption capacity, when the purpose was to recover useful substances in the filtrate, the adsorption capacity of ceramics was a factor that reduced the recovery rate of useful substances.

C Embodiment] A preferred embodiment of the present invention will be described below based on the drawings. A 2.5 mm thick alumina ceramic filter prepared to have an average pore diameter of 2 μm is attached to the filtration device shown in the figure, and the 10% polysulfone/dimethylformamide solution stored in the stock solution tank 2 is passed through the peristaltic pump 3. After lightly wiping both surfaces of the ceramic filter, it is placed in water and left for 30 seconds to form a polysulfone film on the surface, and the liquid in the stock solution tank 2 of the filtration device shown in Figure 1 is mixed with water. When the water was replaced and passed through the ceramic filter 1 impregnated with the 10% polysulfone/dimethylformamide using the pump 3, only dimethylformamide was dissolved in the water and removed. It was clear that the filtration filter 1 prepared in this manner did not allow E. coli to pass through it, but allowed bacteriophage and DNA to pass through it without adsorbing it.
