REMOVAL OF SILICA | Water Treatment | Waste Water

In high-pressure boilers, the amount of silica must be kept very low, since silica dissolves even in steam, thereby the silica going along with the steam deposits on turbine blades, nozzles, etc. At about 40 kg/cm steam pressure, about 5 ppm of silica dissolves in steam and goes along with it. The corresponding amount of dissolved silica in
