The filtration performance of non‐woven thick synthetic membranes used as filter fabrics is predicted from a proposed analytical method. The morphological analysis of many commercial fabrics has been utilized to identify internal structure parameters responsible for their hydraulic properties and also to predict the water permeability and the retention of particles in these fabrics. Experimental filtration tests were performed to gather data on the water permeability used in predicting clogging level. Also fibres' density and pore size histograms of fabrics were measured with an Image Analyser and a relationship was developed between the water permeability and the fibres' density. Finally it was found that the pore size histogram of non‐woven fabrics of thickness greater than 1.5 mm could be calculated simply by measuring its water permeability and using an empirical correlation.
