An improved and rapid process for purifying a silica hydrogel of soluble contaminants which comprises reducing the hydrogel to a controlled particle size range and thereafter treating the sized hydrogel in a continuous three-step operation. Treatment involves first dewatering a hydrogel slurry, washing the resulting hydrogel with acidified water, followed by washing with ammoniated water.
Silica, in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies.In rain hail and snow, silica content range from 1 to 2.8 ppm. In the analyses of various surface and ground waters, silica content range from 1 to 107 ppm.This refers to soluble silica content and not to the silica that may be present in the suspended matter.
