Silica in boiler feed water - metrohm.c

2017-6-8 · Excessive silica concentrations in the boiler feed water can lead to deposits on turbine blades and must therefore be avoided. Silica analysis is carried out via differential photometry using a leading-edge technology thermostatic cuvette module for non-sample contact at the detector. Typical concentration ranges for silica are 0–50 ppb and 0–1 ppm or higher.</p>

REMOVAL OF SILICA - Water Treatment of Sili

Water Treatment of Silica. Natural waters, generally, contain about 5-8 mg/l of silica (Si0,). Another important source of silica in water is the sand watertreatments filter.When water treated by lime-soda process is filtered through a sand water filter, a good amount of silica dissolves in it (forming calcium and magnesium silicates) due to alkaline nature of waters.
