Aquafit 4 Use - Silica removal from paper mill

Silica is present in paper mill effluents in a significant concentration. Silica mainly comes from the sodium silicate (Na2SiO3) added during the deinking process. Na2SiO3 is required in the process to perform several functions: it stabilizes hydrogen eroxide used to bleach pulp in the pulper;; it has buffering and saponification.

Silicon Carbide Production Process - Washington Mills

Silicon carbide crude is produced by mixing silica (SiO2) with carbon (C) in an electric resistance furnace at temperatures around 2,500 C. The chemical reaction in the SiC process may be represented by the formula: SiO2 + 3C SiC + 2CO. Washington Mills employs two different manufacturing methods for producing SiC.
