A raw water channel spacer capable of suppressing formation of a concentration polarization layer in a region in the vicinity of a separation membrane in a raw water channel, and a spiral wound membrane element including the same are provided. A raw water channel spacer is formed by superposing a first yarn row and a second yarn row, and includes alternately a first mesh structure having a configuration in which first rectangular meshes formed of the yarn rows are continuous in an extending direction of the second yarn row, and a second mesh structure having a configuration in which meshes are continuous in the extending direction of the second yam row such that an interval in the second yarn row is smaller than an interval of the second yarn row forming the first mesh structure.

An electrochemical separation device includes a first electrode, a second electrode, and a cell stack including a plurality of sub-blocks each having alternating depleting compartments and concentrating compartments and each including frame and channel portions disposed between the first electrode and the second electrode. An internal seal formed of a first material is disposed between and in contact with the channel portions between adjacent sub-blocks in the cell stack and configured to prevent leakage between depleting compartments and concentrating compartments in the adjacent sub-blocks. An external seal formed of a second material having at least one material parameter different from the first material is disposed between and in contact with the frames of the adjacent sub-blocks in the cell stack and configured to prevent leakage from an internal volume of the electrochemical separation device to outside of the electrochemical separation device.

A composite filter-cartridge, a composite filter-cartridge assembly for a water purifier and a water purifier are provided. The composite filter-cartridge includes a pretreatment filter-cartridge, a fine filtration filter-cartridge and an activated carbon filter-cartridge arranged sequentially from outside to inside. The fine filtration filter-cartridge includes a first water collecting pipe and a fine filtration membrane. The activated carbon filter-cartridge includes: a second water collecting pipe, an outer circumferential wall of the second water collecting pipe except a lower end thereof and an inner circumferential wall of the first water collecting pipe being spaced apart from each other; and a activated carbon, lower ends of the activated carbon and the second water collecting pipe being in sealed connection, a water outlet hole being formed in the activated carbon and penetrating the activated carbon axially, and an upper end of the water outlet hole being closed.

A thermally sterilizable fluid filter (10) for concentrating substances contained in a fluid by way of micro-, nano- or ultrafiltration of the fluid, particularly for concentrating a pharmaceutical precursor and/or intermediate, in particular a vaccine, in a fluid. The fluid filter has a filter housing with a fluid inlet, a retentate outlet and a permeate outlet. A filter cartridge is arranged in the filter housing (12) and has a filter medium of a ceramic material and/or a ceramic composite material. The filter cartridge is arranged held with axial play on the filter housing.
