Abstract
The present invention is directed to a method of sealing the free end of a hollow fiber membrane for use in a single header filtration module by dipping the end of the membrane into a low-viscosity light-curable adhesive and curing the adhesive. The invention further encompasses the resulting sealed hollow fiber membrane with a diameter that is only slightly larger than the diameter of the unsealed membrane.
