There are many routine evaluating indicators widely adopted for the evaluation of hollow fiber porous membranes, which include pore size/diameter, pore size distribution, porosity, permeating flux, rejection rate, and molecular weight cut-off, et al.
But the membrane performance data provided by different membrane corporations could hardly be directly compared, owing to the evaluation method and the evaluation conditions of the membranes are quite different. What’s more, there’re still many important and factual properties of the membranes could not be correctly characterized or described owing to the lack of widely accepted evaluation method or indicators. The lack of uniform standard on the evaluation of commercial hollow fiber membranes greatly encumbered customers in selecting a suitable membrane.
In this paper, the main performance indicators and relative evaluation methods were introduced, in order to construct and uniform the evaluation standard of hollow fiber porous membranes, provide reliable method for the evaluation, selection and application of commercial hollow fiber porous membranes.
