Effect of Elevated Temperature on Ceramic Ultrafiltration of Colloidal Suspensions

摘要: AbstractHigh-temperature wastewaters and process waters in many industries have been a concern, compromising the integrity of polymeric membranes filtration processes or requiring temperature to be lowered for further treatments. Filtration employing ceramic membranes, however, can treat high water owing inherent thermal resistance materials, may benefit from increases permeate flux attributable decreases viscosity at higher temperatures. In this study, performance ultrafiltration membrane was evaluated feed solutions containing colloidal silica temperatures between 25 90°C, range encountered various industries. Results indicated net increasing production elevated temperatures, with nearly 90% increase steady-state 90°C. However, lower than that observed pure filtration, which ...
