Features of ultrafiltration purification of industrial solutions of starch and treacle production

The paper examines the specific output stream and the rate of detention of a semi-permeable ultrafiltration membranes, UPM, UAM150, UAM200 in the separation process, waste starch and syrup production JSC., the company "Krakhmaloprodukt" low-pressure baromembrane method. As a result of the analysis of experimental data, the dependence of the retention factor of ultrafiltration membranes UPM-K, UAM150, UAM20 at different concentrations of the dissolved substance was obtained and analyzed. For the theoretical calculation of the process of ultrafiltration separation technology solutions of starch and syrup production modified mathematical expression for the factor of detention and the specific output stream and the numerical values of the empirical coefficients. Ultrafiltration for the separation of waste starch and syrup production the technological scheme of purification, separating the main elements of which was the pre-filter, biofilter, cascade ultrafiltration apparatus, centrifugal and plunger pumps, as well as the adsorption column...
