Zusammenfassung:The present invention relates to a composite filter having a lateral flow type RO filter for accommodating, in a filter housing, an RO filter for filtering heavy metals and the like harmful to a human body, which are contained in raw water such as tap water or the like, and a pre-processing filter for filtering chlorine components in raw water. According to one embodiment of the present invention, the composite filter having a lateral flow type RO filter comprises: a filter housing of a nipple type which has a water inlet formed at one end thereof and a purified water outlet and a concentrated water outlet formed at the other end thereof; a pre-processing filter of a cylindrical shape which is accommodated in the filter housing, through which raw water introduced into the filter housing moves in a radial direction from the outside toward the inside, and which has a hollow center; a lateral flow type RO filter which is accommodated in the hollow center of the pre-processing filter, wherein the raw water passing through the pre-processing filter moves in a longitudinal direction along a reverse osmosis membrane from an outer surface of the RO filter that is wound in a bag shape; and a central tube which is embedded in a center of the RO filter and formed with a purified water moving passage therein to collect purified water passing through the RO filter to move the same toward the purified water outlet. 게시된 내용은 수돗물 등의 원수 중에 함유되는 인체에 유해한 중금속 등을 여과하는 RO필터 및 원수 중의 염소 성분을 여과하는 전처리필터를 필터하우징에 수용하기 위한, 측면유동형 RO필터를 갖는 복합필터에 관한 것으로, 본 명세서의 일 실시예에 의한 측면유동형 RO필터를 갖는 복합필터는 일단에 원수 유입구가 형성되고, 타단에 정수 배출구 및 농축수 배출구가 형성되는 니쁠타입의 필터하우징; 상기 필터하우징에 수용되고, 상기 필터하우징에 유입되는 원수가 바깥쪽에서 안쪽을 향하여 반경방향으로 이동되며, 중앙이 비어 있는 원통형태의 전처리필터; 상기 전처리필터의 비어 있는 중앙에 수용되는 측면유동형 RO필터, 상기 전처리필터를 통과하는 원수가 자루형태로 감긴 상기 RO필터의 외측면에서 역삼투막을 따라 길이방향으로 이동하게 됨; 상기 RO필터의 중앙에 내설되고, 상기 RO필터를 통과하는 정수수를 집수시켜 상기 정수 배출구로 이동시키도록 내부에 정수이동통로가 형성되는 센트럴튜브;를 구비하는 것을 특징으로 하는 측면유동형 RO필터를 갖는 복합필터를 제공한다.
