Abstract:

The experiments on concentration of hydrothermal solutions by membrane filters for silica sols production were carried out. Three types of membranes were tested. The first type was ceramic membrane filters with diameters of pores 0.1-0.3 mm and average pores diameter 0.2 mm. The second type was filters with pores sizes in the range of ultrafiltration
