Semi-empirical model for the evaluation of protein retention during tangential filtration of whey using ceramic membrane elements

摘要

This paper considers some results of using tangential filtration by ceramic membrane elements for the treatment of whey. Five samples of filtrate which was obtained by four different ceramic membranes were used for experiment. These membranes have pore size 400, 200, 100, 65 and 50 nm. A semi-empirical model for the evaluation of protein retention during tangential filtration of whey using ceramic membrane elements is discussed in more detail below. The optimal membrane pore size for specified applications has been determined on the base of the proposed model. Results of the work could be used in the calculation of filtration equipment to improve the efficiency of dairy production and neutralize their waste water.
