<p>PROBLEM TO BE SOLVED: To provide a flat membrane cartridge which is high in durability and reliability and large in permeation flux while keeping its filtration performance. SOLUTION: In the flat filtration separation membrane cartridge K1 which is immersed in a water treatment tank for cleaning water to be used and filters and separates non-clean water components by a flat membrane single body to extract filtrate, the flat membrane single body is composed of an FRP membrane having continuous pores. Two flat FRP membrane single bodies A1 and A2 arranged oppositely with a concave deformation preventing member 11 for preventing concave deformation during water absorption filtration set between them are integrated with their peripheral parts kept watertight by a watertight material 12. A permeation channel 4 is formed by the space between the flat membrane single bodies A1 and A2, and a scupper 1 connected to the channel 4 is provided. A drain pipe connection tool C is fitted to the scupper 1 to collect filtrate.</p> |
