Calcium meters are used for measuring calcium in water. The concentration of calcium in water is also known as water hardness. Hard water contributes to scaling in boilers and industrial equipment. Measuring calcium in water is important in industrial settings in order to prevent costly breakdowns that can be caused by limescale.

levels that would precipitate silica and interfere with the corrosion inhibiting film formation on metals. Thus, for high COC operation, hardness removal equipment must provide excellent water quality and reliability. Hardness leakage or upsets in pretreatment necessitate blowdown to lower hardness levels to avert hardness and silica precipitation.
Scale formation is costly to production operations, as it causes a reduction in flow through transfer lines, builds on the surface of equipment, restricts mechanical actions, and accumulates in tanks and impoundments. Reduction of scaling can be achieved by reducing concentrations of hardness, alkalinity and silica.

Aug 13, 2012 · The removal of contaminants, such as silica, from water can be a challenging proposition. Some examples of industries that need to remove silica from the water before discharge or reuse are: cooling towers, boiler blow feed water or boiler blow down water, carwashes, semi-conductor manufacturers and steam injection oil recovery wastewater.
Cab-O-Sil is a fumed silica filler used as a thickening agent in solvent based resin formulations.
In contrast, quartz has a Vickers hardness of approximately 1,200 (7 on the Mohs scale), which is roughly 1.5 times harder than chrome steel. Quartz was chosen for comparison because it is one of the most abundant minerals in soil (primarily sand). Silica-dioxide crystals are commonly referred to as quartz and can be found in most soils.
