What is Silica:
Silica is clear and tasteless. It is the oxide of silicon, the second most abundant element in the earth's crust. Silica is present in most natural waters. Silica is commonly found as quartz and sand. Typical concentrations lie between 1 and 30 mg/L, but higher concentrations exist in brackish waters and brines. Silica can form a harmful scale on equipment and heat transfer surfaces, particularly steam turbine blades.
Silica Exposure and Health Risks:
Exposure to high doses of silica leads to non-permanent, short-term inflammation. It will irritate the skin, eyes, and respiratory tract. Organ damage and immunological stress can occur through prolonged or repeated exposure.
Regulations:
There are no listed regulations or restrictions for Silica concentration in water.
Measuring Silica:
Dissolved Silica concentration in water can be measured in units of parts per million (ppm). We carry instrumental kits from CHEMetrics that determine Silica levels in water. All of our Silica products can be viewed HERE.
