The Food and Drug Administration considers silica as a safe substance. In well and surface water, it can range from 1-100 parts per million as dissolved (reactive) or undissolved (colloidal) silica. Earliest recorded of the silica sand has been traced back to the year 1804 when a man by the name John Gibb, was able to design as well as install an experimental filters. In solution it can exist as silicic acid or silicate ion, depending upon the pH value. In lime softening the silica is co-precipitated along with magnesium present in the water (or added if … It is a hard, glassy mineral substance which occurs in a variety of forms such as sand, quartz, sandstone, and granite. Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. This is called the well screen. Silica is a hard, glassy-like mineral that is found dissolved in water as a result from the bedrock it passes through, like sandstone and granite.

If sediment is present or su spected due to color or cloudiness, also test for tannins and turbidity. Both of these techniques are non-specific for silica, meaning they also remove all other ionic components along with the silica. Unreactive silica is polymerized or colloidal silica… Silica levels above 40 or 50 parts per million in water will eventually result in this permanent haze on your glass and ceramic surfaces. In this case, the CTBD water contained total silica levels ranging from 80 to 120 mg/L which would limit the RO recovery rate if not substantially reduced.
