REVERSE OSMOSIS FILTERING MODULE AND REVERSE OSMOSIS FILTER COMPRISING SAME

A reverse osmosis filtering module includes: a purified water discharge pipe in which a purified water discharge path is formed, and which has a communication hole that is formed on an outer periphery thereof and communicates with the purified water discharge path; a reverse osmosis filtering part including a reverse osmosis filtering member in which a purified water flow space is formed, and which is wound around the purified water discharge pipe such that the purified water flow space communicates with the communication hole; a first flow channel formation cap provided at one side and having an inlet hole; and a second flow channel formation cap provided at the other side of the reverse osmosis filtering part and having an outlet hole.

Sanitary Membrane Cartridge for Reverse Osmosis Filtration

A sanitary membrane cartridge for use in reverse osmosis filtering includes an outer housing, a central core tube, and a membrane leaf wound around the central core tube to form a cylindrical filter. The cartridge further includes a sealant layer disposed around the cylindrical filter to form a sealed filter, the sealed filter disposed within the housing. The sealant layer preferably has a surface roughness value, Ra, ranging from about 0.38 m to about 0.82 m. The cartridge further includes a brine seal, disposed between the sealant layer and the housing, having one or more notches formed on an outer diameter of the brine seal such that the feed flow through the notches allows bypass flow, between the sealant layer and the housing, of 1% to 25% of a total feed flow through the sealed filter.

Filtration unit

A filtration unit for purifying or treating fluid that includes one or more membrane units having a permeate section. The permeate section of the membrane units is fed fluid that passes through a sealing insert having a fluid inlet and a passage that discharges in fluid communication with the permeate section. The sealing insert is arranged in a support frame of the membrane unit to form a fluid channel for delivering fluid through the insert and along an outer perimeter surface that maintains performance of the membrane unit during operation.
