A small-sized plate type fluid treatment apparatus for filtration and separation of fluid, transferring substances between fluids through membranes or passing specific substances contained in the fluid through membranes. Said apparatus consists of a plurality of stacked membrane arrangements which comprises membrane support-plates, each being molded in thickness of 1.2 mm or less by means of embossing or press work, and a single membrane interposed between said membrane support-plates. The membrane support-plate composing the membrane arrangements of this apparatus is so designed that the 1st fluid is fed into the space defined by the 1st membrane support-plate and the membrane, and the 2nd fluid is fed into the space defined by the 2nd membrane support-plate and the foresaid membrane, with no abruptly narrowed passage for fluid. Therefore, even when as thin a membrane support-plate as 1.2 mm or less in thickness is used, residence of bubbles is prevented in the fluid in the performance of the apparatus.

A plate type fluid treatment apparatus comprising: a plurality of stacked membrane support plates having a thickness not greater than 1.2 mm, each said membrane support plate having a face side and a reverse side, said plates being stacked in a stacking direction such that each of said face side of one of said plates faces the reverse side of an adjacent plate and each said reverse side faces the face side of an adjacent plate; a single membrane interposed between each of said plates; a first membrane supporting zone on a central portion of each said face side; a second membrane supporting zone having a configuration different from that of said first membrane supporting zone on a central portion of each said reverse side; first through fourth fluid manifold holes on the peripheral portions of each of said plates, said fluid manifold holes being aligned so as to form a manifold in said stacking direction; inlet and outlet ports for each of said first and second fluids, said inlet and outlet ports respectively communicating with said fluid manifold holes on the peripheral portions of said plates; first fluid introducing means in each said plate for introducing said first fluid from said first fluid manifold hole into the space between said first membrane supporting zone of each said plate and one of said membranes; and second fluid introducing means in each said plate for introducing said second fluid from said second fluid manifold hole into the space between said second membrane supporting zone of each said plate and another of said membranes; wherein said separate first and second fluid introducing means in each said plate prevent mingling of said fluids; wherein each of said membrane support plates has a thickness at said membrane supporting zones of d=5 to 500meach first membrane supporting zone having a large plurality of projections thereon wherein d at least equals or is greater than the total volume of said projections divided by the area of said first membrane supporting zone, and each of said second membrane supporting zones being substantially flat; and wherein each said membrane support plate comprises a first member including said first and second membrane supporting zones, said manifold holes and fluid introducing means connecting said first and second membrane supporting zones with said first and second manifold holes; and a second member on either side of said first member, each said second member including said manifold holes and an opening in a zone corresponding to said membrane supporting zones; wherein said first and second members are located adjacent one another so that each of said fluid introducing means, together with a portion of said second member, form a tunnel-like fluid flow introduction path.
