Abstract:
A fluid-treatment device, comprising:a flexible housing, the housing having an inlet port and an outlet port and being of elongate shape divided along a length of said housing into two parts defining a space internal to said two parts, wherein each part is corrugated transversely both internally and externally with respect to said space across a width of each part go that the housing is flexible transversely allowing the inlet port and the outlet port to be displaceably offset from each other transversely with respect to a longitudinal centerline of the housing when the housing is in an unflexed state, said two parts of said housing each having a set of triangular tooth formations extending along mating portions of said housing that mate with one another; and a fluid-treatment element within said space internal to said two parts, said fluid-treatment element being pleated across a width in a zigzag fashion with sides of said fluid-treatment element following a profile of said teeth formations on the housing, and with the pleats being substantially aligned with said corrugations and wherein opposite edges of said fluid-treatment element are supported and sealed between said teeth formation of the two parts of the housing such that fluid flowing between the inlet and outlet ports is confined to flow through the fluid-treatment element.
