Abstract: Fouling and subsequent cleaning study of spiral wound reverse osmosis (RO) membrane modules were done. The membrane modules consisted of polyamide (PA) with cross sectional area of 1m2. RO membrane fouled by polysaccharides equivalent to sodium alginate (SA), with different doses of SA (200, 300, 500 ppm) was and calcium ions (0.5 to 2 mM) at various operating conditions. Initial flux was the 1.132×10-5m3/m2 at 1379 kPa and it decline to 1.02×10-5m3/m2.s after 5 h.rnFouled membrane modules were cleaned by using different chemical agents, such as, anionic surfactant, e.g., sodium dodecyl sulphate (SDS) and metal chelating agent e.q., ethylenediaminetetraacetic acid (EDTA). Flow rate of 9 lpm and transmembrane pressure drop of 69 kPa were used to fouled membrane modules. The cleaning performance of membrane module in terms of flux recovery with variation of cleaning agent dose was studied. It was observed that with increase of operating time and cleaning agent dose, cleaning efficiency of membrane module increased. The optimum doses of SDS and EDTA as cleaning agents were 8 and 1mM, respectively. It was noted that EDTA had a better cleaning efficiency than SDS.
