Abstract

Scaling of heat transfer surfaces in evaporative desalination by the alkaline scales, calcium carbonate and magnesium hydroxide, is prevented by adding to the water being processed effective amounts of at least one water soluble silica-containing (SiO2) compound selected from the group consisting of the alkali metal silicates and silicic acid.
