Typically, silica exists in two forms in the water supply: (1) reactive silica; and (2) colloidal silica. Silica causes etching, scratching, and spotting on glassware and other fixtures.<\/p>\n<p>Removal of silica is\u00a0usually\u00a0done as a means of preventing wear\u00a0and\u00a0damage to equipment<strong>.<\/strong>\u00a0This\u00a0is because silica can accumulate on surfaces\u00a0and appear as\u00a0hard mineral deposits known as scale. Scale deposits\u00a0will\u00a0reduce the efficiency of heating and cooling\u00a0and\u00a0interfere with the ability to operate systems within a defined pressure range.\u00a0Silica\u00a0scaling can compromise the efficiency, performance, and safety of\u00a0water using\u00a0equipment such as boilers, turbines, piping, and\u00a0even\u00a0filtration\u00a0systems.<\/p>\n<p>Silica is most commonly found on Earth in the form of quartz. It is also a significant component of sand. In fact, after oxygen, silicon is the second most abundant element present on our planet. The chemical composition of silica is SiO2.<\/p>\n<p>Silica is frequently confused with hardness.\u00a0 Sometimes when a water softener is installed, it may seem that there still is hardness in the water because of etching or spotting.\u00a0 You can perform a very simple test to determine if it is hardness or silica. Just apply vinegar to the stains, and if they are removed by the vinegar, it is hardness.\u00a0 If the vinegar does not remove it, it is most likely silica.<\/p>\n<p>Let\u2019s look at the most common methods of dealing with and removing silica.<\/p>\n<\/div>\n<\/div>\n<div>\n<h2 style=\"text-align: left;\"><strong><span style=\"font-size: 23.04px; color: #008080;\">Lime Sofftening<\/span><\/strong><\/h2>\n<div data-content-type=\"text\" data-appearance=\"default\" data-element=\"main\">\n<p>Lime softening requires the addition of calcium hydroxide to the water supply. This causes the calcium carbonate and magnesium carbonate (commonly called \u201chardness\u201d) to precipitate out. The silica particles are absorbed by the calcium and magnesium hydroxides.\u00a0 The most common applications for lime softening are in large cooling towers, and large boiler feeds.<\/p>\n<p>This method requires a large capital investment and is very costly due to the chemicals needed and the sludge generated, which requires disposal. This is a method that would not be economically practicable in a residential application.<\/p>\n<\/div>\n<\/div>\n<div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<div><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3837 aligncenter\" src=\"https:\/\/khangngoc.com\/wp-content\/uploads\/2021\/12\/Lien-quan-den-Silica-3.jpg\" alt=\"C\u00e1c c\u00e1ch lo\u1ea1i b\u1ecf Silica t\u1ed1t nh\u1ea5t\u00a0\" width=\"443\" height=\"332\" srcset=\"https:\/\/khangngoc.com\/wp-content\/uploads\/2021\/12\/Lien-quan-den-Silica-3.jpg 1024w, https:\/\/khangngoc.com\/wp-content\/uploads\/2021\/12\/Lien-quan-den-Silica-3-768x576.jpg 768w\" sizes=\"auto, (max-width: 443px) 100vw, 443px\" \/><\/div>\n<div style=\"text-align: left;\">\n<p><strong style=\"font-size: 23.04px; color: #333333;\"><span style=\"font-size: 23.04px; color: #008080;\">Ion Exchange<\/span><\/strong><\/p>\n<\/div>\n<div>\n<div style=\"text-align: left;\">\n<div data-content-type=\"text\" data-appearance=\"default\" data-element=\"main\">\n<p><span class=\"TextRun SCXW249813521 BCX0\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"auto\"><span class=\"NormalTextRun SCXW249813521 BCX0\">Silica molecules have a negative charge, so anion resin is needed to remove them.
