27/5/2003· However, occasional measurements of total silica," i.e., soluble and colloidal," are recommended to ensure no silica is lost to precipitation and deposition. These measurements require sample treatment or elaborate instruments and techniques (e.g., inductively coupled plasma atomic emission or atomic absorption spectroscopy) and are not practiced routinely in the field.Read-out Instrumentation Signpost: Silica monitoring .Silica deposition on turbine blades can cause defects and an imbalance in the blades, which in turn causes vibration and could even result in failure. Silica deposition in boiler tubes is also to be avoided because it causes a loss of thermal efficiency, thereby reducing the efficiency of the whole plant.How to Select a Chemical Coagulant and Flocculant. - SSWMsilica particles. Often the effect that turbidity has is dependent on the amount present rather than the classification. In low turbidity waters (<10 NTU) an organic polyelectrolyte should not be considered. The choice of inorganic coagulant should be one that 3Read-out Instrumentation Signpost: Silica monitoring .Silica deposition on turbine blades can cause defects and an imbalance in the blades, which in turn causes vibration and could even result in failure.
