Abstract:

The use of a ceramic membrane of 0.1 μm in pore size to concentrate pectin solution was evaluated. The effects of operation temperature, trans-membrane pressure and pectin concentration on permeation flux were investigated. The results showed that permeation flux tended to remain stable after 1 h of running. A stable permeation flux of 145 L/(h·m2) was obtained under the conditions of trans-membrane pressure 0.08 MPa, pectin concentration 0.5% and operation temperature 55 ℃.

Key words: ceramic membrane, pectin, concentration, permeation flux
