Fluid treatment arrangements and methods of making fluid treatment arrangements

摘要

A fluid treatment arrangement (10) may include a fluid treatment unit (13) having a multilayer structure. The multilayer structure may include at least one feed layer (15), at least one permeate layer (14), and at least one layer of a permeable fluid treatment medium (16) 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 (21) which overlies the first end surface of the fluid treatment unit. The thermoset directly bonds to the thermoplastic sheet.
