PCT No. PCT/JP79/00197 Sec. 371 Date Mar. 28, 1980 Sec. 102(e) Date Feb. 15, 1980 PCT Filed Jul. 26, 1979 PCT Pub. No. WO80/00309 PCT Pub. Date Mar. 6, 1980. The invention provides a tubular membrane separation apparatus useful for ultrafiltration and reverse osmosis. A tubular separation element (1) is fitted in a porous pressure-resistant tube (2) which is inserted in a liquid collector tube (3) of larger diameter. The collector tube (3) is detachably connected to connector tubes (6) by joints (4). Each end of the separation element (1) is held between the inner surface of the joint (4) and the end of the connector tube (6) and thereby sealed. The separation element (1) is replaceable, and the apparatus can be disassembled for cleaning.
