Ceramic membrane fouling and cleaning during ultrafiltration of limed sugarcane juice

Microfiltration of raw soy sauce: membrane fouling mechanisms and characterization of physicochemical, aroma and shelf-life properties

“…R f is considered as the sum of the reversible (R rf ) and irreversible (R irrf ) fouling resistances (m À1 ). 15 R rf resistance results from concentration polarization and cake fouling on the membrane surface, which is removable by simple cleaning. On the contrary, R irrf resistance originates from pore blocking or substance adsorption on the membrane surface or pores, which is hardly removed by simple cleaning.…”

The application of pressure-driven ceramic membrane technology for the treatment of industrial wastewaters – A review

“…Ceramic membranes are important processes in food industry. They can be used for a variety of purposes such as treatment and clarification of effluents generated during dairy, juice, beverage, beer, wine, vinegar , sugar, olive, corn, soy sauce, meat, poultry and seafood production processes [160][161][162][163][164][165][166][167][168][169][170][171][172][173][174][175][176]. Ceramic MF and UF have received a lot of attention in the treatment of food industry wastewaters because of their long-term solid performance in these applications over the polymeric membranes [12].…”

“…They found that the most effective membrane cleaning solution was 1% NaOH mixed with 0.5% NaClO [20]. Li et al (2018) led in the process of ultrafiltration of limed sugarcane juice by ceramic membranes. To oppose fouling, membranes are washed in distillated water, followed by a mixture of 1.0% NaOH and 0.5% NaClO (similar to above) and a 0.5% HNO3 solution.…”
