Abstract

필터엘리멘트(fillter element)에는 천연 또는 합성고분자로된 중공사형 분리막(hollow fiber type separation membranes)의 번들(bundle)과 열가소성 수지로된 시일링부(sealed part)를 구성된다.
그번들은 적어도 하나외 그 말단부(terminai part)에 개구를 가진다.
그 시일부재는 그 고분자의 용융온도 또는 분해온도보다 낮은 온도에서 그 번들에 접찹되어 그 고분자와 상용성이 없고 접착계면을 남긴 반용융상태에서 그 번들의 개구를 수밀하게 시일링(sealing)하도록 한다.
