ABSTRACT:
A method of treating water containing silicon-containing impurities in a concentration of up to 10,000 parts per million by weight of the water, by contacting the water over a period of time with a particulate solid which entrains silicon-containing impurities in the water and subsequently separating the water from the particulate solid, wherein the particulate solid is a high alumina cement which is anhydrous when first contacted by the water.
