ABSTRACT:
A problem in the manufacture of filters using tubular membrane bundles is keeping potting material from flowing into the openings at the ends of the tubes. A preferred embodiment of a method for manufacturing a tubular membrane filter employs a non-contact heat source such as radiant heating to melt the tips of the tubular membranes. This prevents the migration of potting material into the tubes when the potting material is flowed into the ends of tube bundles during the manufacturing process for a filter.
