Abstract:
1. A method of making a fluid treatment arrangement comprising: modifying at least a first surface of a thermoplastic sheet to enhance a bond between a thermoset and the first surface of the thermoplastic sheet; forming a fluid treatment unit having a multilayer structure including a feed layer, a permeate layer, and a layer of permeable medium positioned between the feed layer and the permeate layer with a feed side of the permeable medium fluidly communicating with the feed layer and a permeate side of the permeable medium fluidly communicating with the permeate layer, wherein forming the fluid treatment unit includes applying a thermoset to one or more of the feed layer, the permeable medium layer, and the permeate layer; and directly bonding the thermoset on a first end surface of the fluid treatment unit to the modified first surface of the thermoplastic sheet.
