Abstract
필터여재가 제공된다. 본 발명의 일 실시예에 따른 필터여재는 다공성의 제1지지체 상부 및 하부 각각에 순서대로 적층된 다공성의 제2지지체, 및 나노섬유웹을 구비하고, 상기 나노섬유웹에서 여과된 여과액이 상기 제1지지체 방향으로 흐르는 유로가 형성된 필터여재로서, 상기 제1지지체, 제2지지체 및 나노섬유웹은 각 층의 평량 및 두께에 대한 소정의 조건을 만족하도록 구현된다. 이에 의하면, 필터여재는 수처리 운전 중 필터여재의 형상, 구조 변형, 손상이 최소화되고 여과효율이 우수하며, 유로가 원활히 확보되어 높은 유량을 가질 수 있다. 또한, 역세척시 가해지는 높은 압력에도 필터여재의 뛰어난 내구성으로 인해 연장된 사용주기를 가짐에 따라서 각종 수처리 분야에서 다양하게 응용될 수 있다.
