Silicon dioxide (SiO 2) sand and fused quartz are silicas. Silicate minerals constitute about 90 percent of the Earth''s crust. Silicates are anions containing silicon and oxygen (for example, orthosilicate, SiO 44), and several are usually slightly soluble in water, so silicate salts are commonly present in water.
Equipment employed; Limitations; Precipitation softening processes are used to reduce raw water hardness, alkalinity, silica, and other constituents. This helps prepare water for direct use as cooling tower makeup or as a firststage treatment followed by ion exchange for boiler makeup or process use.
