“…Thus, detachment of the membrane-forming material, in particular polymers, is possible over longterm operation, thereby resulting in the deterioration of the membrane performance with time. Pilot plant tests of brackish water treatment using dynamically formed membranes, involving 100 1000-h-long operations, were carried out 3,5,6,8) . However, in these tests, some operation parameters, such as flow rate, were changed several times during each run.…”

“…These membranes generally can reject salts, because of the electric charge of the membrane-forming materials, and they were developed as novel types of reverse osmosis or nanofiltration membranes. Because of the large pure water permeability ( L p ) in facile formation, various types of dynamically formed membranes were extensively developed in research works, − including practical studies. , Since the 1990s, there have been few reports on dynamically formed membranes, probably because many types of reverse osmosis or nanofiltration membranes with excellent properties have been developed. However, the dynamic forming method is attractive in terms of facile surface modification over a large area in a single treatment.…”

The dynamic forming method was first employed for the preparation of fouling-free membranes. The copolymer of 1-carboxy-N,N-dimethyl-N-(2 0 -methacryloyloxyethyl) methanaminium inner salt and n-butyl methacrylate was selected for the surface modification polymer to realize the fouling-free property in this study, and its aqueous solution was filtered using a commercially available ultrafiltration membrane. The surface modification polymer was thus deposited on the ultrafiltration membrane in a facile manner over several minutes. Compared to the unmodified membrane, the dynamically formed membrane with the surface modification polymer layer proved to have excellent fouling resistance against 1000 ppm bovine serum albumin (BSA) solution. In particular, the dynamically formed membrane was hardly fouled and maintained its initial flux when the filtration flux was set below 6 Â 10 À6 m 3 m À2 s À1 .

SynopsisMembranes were dynamically formed from poly(acry1ic acid), poly( 1-methyl-2-vinylpyridinium iodide), and methylcellulose on a Millipore filter. The effects of the conditions of membrane formation on reverse osmosis performances and the membrane structure were investigated. The primary factors that affect membrane performance were ascertained to be the kind and concentration of salts and the pH of the preparing solutions, the concentration and the polymerization degree of the membrane materials, the pore size of filters, and the pressure and circulation velocity during membrane formation. Two types of dynamically formed membranes, the membranes inside the filter and the membranes on the filter, were distinguished.
