Abstract:
1. The process for forming a fluid processing module having a feed port, and at least one permeate port that comprises: forming at least one fluid permeable spacer layer having a feed port and at least two membrane filter layers each having a permeate port wherein said at least one spacer layer is positioned alternately with said at least two filter layers in vertical direction, providing at least one thermoplastic section secured to one end of said two filter layers extending into said ports in a configuration such that when said at least one thermoplastic section is melted, sealing of said at least two filter layers in said feed port is effected such that liquid in said at least one permeate port is not admixed with liquid in said feed port, and heat sealing said at least one thermoplastic section in one of said ports by extending a radiant heating element in said port and energizing said heating element to effect heating of said at least one thermoplastic section in said port to effect heating of all the thermoplastic sections in said port simultaneously.
