Fluid treatment arrangements and methods of making fluid treatment arrangements

摘要

A fluid treatment arrangement may include a fluid treatment unit having a multilayer structure. The multilayer structure may include at least one feed layer, at least one permeate layer, and at least one layer of a permeable fluid treatment medium between the feed layer and the permeate layer. The fluid treatment unit may further include a thermoset which holds the layers together and forms at least a portion of a first end surface of the fluid treatment unit. The fluid treatment arrangement may also include a thermoplastic sheet which overlies the first end surface of the fluid treatment unit. The thermoset directly bonds to the thermoplastic sheet.

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.
