One of the possible approaches to remove the Pseudomonas bacteria from surface water by using textile fibrous media has been studied in this article. The attachment of Pseudomonas bacteria inside textile fibrous media was studied using laboratory column experiment which led to the understanding of the physiochemical interaction between textile surface and the bacteria. Colloid‐filtration theory was used to investigate the effects of various physicochemical factors like pH, ionic strength (M) and mass (g) of the porous media on bacterial attachment. The quantitative assessment of bacterial attachment on the textile surface media was carried out by determining the collision efficiency. The physicochemical factors mentioned above were optimized to obtain maximum collision efficiency so as to achieve maximum bacterial attachment on the textile media surface. Bacterial attachment is found to be directly related to the ionic strength of the suspending medium and the mass of the textile media. A significant improvement in collision efficiency is observed when the ionic strength of the suspended medium is increased. Maximum collision efficiency is achieved at high level of ionic strength and medium level of pH with high level of mass of the textile media.
