Research on skim milk ultrafiltration with a reciprocating rotating hollow fiber membrane module
摘要
Abstract
A novel dynamic filtration system of reciprocating rotating hollow fiber membrane was used to UF skim milk solution.The effects of the module＇s geometry parameters and rotating parameters as well as the characteristics of tested fluid on the decline of membrane permeate flux were investigated.The results indicated that a better shear enhancing efficiency could be obtained while the angular velocity and/or the radial distance of membranes from the central hollow shaft were increased.The greater vectors superposition of the flow field and the membrane rotating velocity,which was reflected on a relative greater velocity gradient,would be obtained once the reciprocating rotation cycle was optimized.Otherwise,simply increasing or decreasing the rotation cycle would weaken the efficiency of shear enhancement.With the same operating parameters,the reciprocating rotation filtration was more favorable in slowing the decline of membrane permeate flux than the dead end filtration or the uni-directional rotation filtration.关键词
