This study attempted an experimental approach to the applicability of the induced reverse osmosis technique in the tubular module concentration unit on the basis of the theoretically predicted contacting effect of an external solution. Keeping a suitable external solution in contact with the feed solution on the low pressure side of the membrane uniformly along the axis of the tubular pressure vessel induced effectively the contacting effect with no evidence of contaminating the feed solution. The asymmetric porous membranes which are appreciated in the reverse osmosis process appeared to be less beneficial in the induced reverse osmosis process. The crux of the technique was found to lie in developing the most suitable backing material for flow outside the membrane.
