“…Concentration of the test solute was kept at 0.100 kg/m3. 15 Concentration of the antifoam was determined with a total organic carbon analyzer (Shimadzu Co., Ltd., TOCSOO). The concentration of the test solute was determined with gel-permeation chromatography (GPC).…”

“…Also, UF experiments have been performed for the determination of structural change and micellar compositions of aqueous mixed surfactant solutions with the aim of investigation and prediction of membrane behavior, substantially affecting micellar enhanced ultrafiltration (MEUF) performance [8,9]. The role of interactions in UF processes, where surfactants are present (e.g., cleaning UF membranes fouled by proteins, antifoam fouling), has been studied in order to extend membrane life, optimize processes, and enhance UF effectiveness [10][11][12]. So far, the main factors (chemical nature of surfactants and membranes, surfactant concentration, pH, ionic strength, additives, etc.)…”

“…But membrane fouling is a common phenomenon and is one of the most crucial problems in its application. Antifoam, which is frequently added to fermentation broth to suppress foaming, often fouls membrane (Cabral ef a L, 1985;Kroner et al, 1986;McGregor et al, 1988;Yamagiwa et al, 1993aYamagiwa et al, , 1993b.…”

“…Hydrophobic polysulphone membranes, however, can be easily fouled by some proteins and/or antifoam (McGregor ef aI, 1988;Yamagiwa et a/., 1993aYamagiwa et a/., , 1993b. To reduce membrane fouling, surfactant precoat treatment is considered to be one of the most attractive methods for practical application because of a relatively simple procedure for membrane hydrophilization (Fane ef a/., 1985).…”
