Abstract
The article presents the results of experimental studies of the process of ultrafiltration of whey with the use of large porous ceramic membranes «Tupolev-Plaza». The structure of the ceramic membrane was studied by scanning electron microscopy, and the absence of shrinkage of the membrane was shown at operating pressures of 0,08-0,38 MPa. An experimental setup based on ceramic membranes and an algorithm for its operation under various operating conditions are considered. The process of ultrafiltration of whey in the presence of a polarization layer on the surface of a ceramic membrane has been investigated, a pulsed regime has been proposed for reducing the phenomenon of concentration polarization. The permeate of milk whey was studied by spectroscopy, the protein content in the permeate was equal to 23 % of the protein content in the starting serum. The selectivity of the «ceramic membrane-polarization layer» system over the protein was 0,77. The expediency of using large-porous ceramic membranes in the process of ultrafiltration of whey is proved.
