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 fluid treatment arrangement comprising:
a fluid treatment unit having a multilayer structure which includes a feed layer, a permeate layer, and a layer of permeable medium positioned between the feed layer and the permeate layer, wherein the permeable medium has a feed side fluidly communicating with the feed layer and a permeate side fluidly communicating with the permeate layer, the fluid treatment unit further including first and second opposite end surfaces and a thermoset which holds the layers of the multilayer structure together and which forms at least a portion of the first end surface, and a thermoplastic sheet which overlies the first end surface of the fluid treatment unit, the thermoset directly bonding to the thermoplastic sheet on the first end surface of the fluid treatment unit.
