ABSTRACT:
The-silica content of cooling water blow-down waters is reduced by contacting these waters with a colloidal alumina which adsorbs a portion of the silica. The blow-down is then dialyzed to produce a permeate having a reduced silica content. In a preferred embodiment of the invention the permeate is recycled.
