Membrane Filtration in the Sugar Industry
Original language description
This research work deals with possibilities of raw sugar juice purification by micro- ultra- and nanofiltration. Conditions that enable to reach such a juice purity for proceeding of crystallization without the prerequisite of the whole complex of purification techniques, which involve liming, carbonation and filtration, were sought. Samples were treated with cross-flow micro- and ultrafiltration on ceramic membranes having mean pore size 20, 50 and 100 nm. Increasing of juice purity and retention of almost 50 % of colour impurities by microfiltration is one of the most important results of this study. For nanofiltration tests, a special cross-flow testing cell with adjustable tangential speed of 0 - 3 m#s-1 has been designed. Several flat polymeric membranes (Osmonics Desal, Hydranautics, Nitto Denko, Filmtec) have been tested. The aim was to find a membrane capable to reject the main part of the melassigenic elements as potassium and sodium ions, i.e. elements that increase amount of
