| 摘要 |
The present invention provides a filtration module comprising a stack of at least two spacers. At least one spacer in the stack comprises a first and a second outer plate and at least one internal permeate channel arranged in between the first and second outer plates such that the outer plates form two of the walls that define at least one internal permeate channel. The at least one internal permeate channel extend between two opposite sides, other than the first and second outer plates, of the spacer. The first and/or second outer plates of at least one spacer are porous or perforated such that liquid may be transported through the pores or perforations to said at least one internal permeate channel. The spacers of the stack are separated by a distance-pieces that are attached to the outer plates along the edge to the opposite sides between which the internal permeate channels extend, thereby forming filtrate channels between adjacent spacers in the stack. The present invention further provides a method for producing a filtration module and a filtration device. |
