Bench scale plant with every hollow fiber module of Du Pont's B-9 type were tested to permeation on the removal of pyrogen from the deionized water. Under permeating conditions of 20℃ liquid temp., 20kg/cm^2 pressure and 50-75% conversion, it were effective to some extent for the removal of pyrogens (Table 1). Regarding with testing of initially pyrogenic deionized water without addition of Bact-lipopolysaccharide by the pilot scale permeaters for long time, the performance of these pilot operating tired for removal of pyrogenic impurity in the deionized water was good with stable reproducibility (Figure and 5).
