Purification Of Water

AbstractExperiments on determination of operational effectiveness of track membranes with different diameter of pores (0.2 – 0.05 microns) for additional purification of water of the first contour of the reactor before ion-exchange resins were carried out. The track membranes detain products of corrosion, and also products of wearing of moving parts of the equipment by the size of > 0.05 microns. Filtration experiments on of water of the first contour of the exploratory reactor of VVR-SM have shown high performance of track membranes.

Limited Testing

Tests were made with five different demineralizing arrangements of ion-exchange resins in the purification of clarified sugarcane juices, but none provided juices superior in quality to those obtained from the reverse-cycle system. Feed juices of variable composition and high purities, and limited testing with the various mixed cycles preclude precise determination of the performance of these arrangements of exchangers, but ash, protein, color, and turbidity removals were insufficient to justify extensive testing. Purity increases obtained with most mixed cycles were found to equal or exceed that from the reverse cycle, indicating that more crystalline sugar would be available from the product juices, but the advantage of such additional sugar would be cancelled by the greater expense of installation and operation of four or five exchanger-beds, as compared with that for the three-bed reverse-cycle system.

Abstract Sorbitol is extracted from bakery products with water, and nonreducing sugars are inverted by acid hydrolysis. Carbohydrates other than the sugar alcohols are degraded in alkaline solution and reaction products are removed by ion exchange resins. Sorbitol is determined by the amount of periodate consumed in oxidation and identified by thin layer chromatography.
