  • Sodium silicate Wikipedia

    Water treatment. Sodium silicate is used as an alum coagulant and an iron flocculant in wastewater treatment plants. Sodium silicate binds to colloidal molecules, creating larger aggregates that sink to the bottom of the water column. The microscopic negatively charged particles suspended in water interact with sodium silicate.

  • WHAT ARE SILICATES AND WHY ARE THEY IN

    Silicates are silicon-oxygen anions that combine with metals to form silicate salts. Most water contains silicates due to water moving over and through natural deposits and natural physical and chemical weathering processes. The effects of silicates can either be positive or negative depending on the functions of the water system.
