Calcite Granules For Water Filter

Day 24/08/2024

Calcite/Limestone is a naturally-occurring mineral rock consisting of approximately 95% calcium carbonate and 3% magnesium carbonate. Calcite Granules is commonly used in residential and commercial water filter applications to neutralize acidic or low pH water to reduce corrosiveness and balance pH prior to iron treatment. Calcite is slow-acting for controlled pH neutralization of low hardness water with a pH level ranging from 5.0 to 6.9.

1. What is Calcite?

Calcite is a common mineral of the calcite group, belonging to the calcite-rhodochrosite series. It is a carbonate with the molecular formula CaCo3. It belongs to the triangular system, in nature we can find it from amorphous to an infinity of different crystals, being the most common or outstanding the scaly, pointed or dogtooth, hexagonal, rhombic… Like quartz, we can find it all over the planet.

Calcite Granules is a naturally occurring high purity calcium carbonate for water filter media application.

2. Chemical formula: CaCO3 (Calcium Carbonate)

3. Physical properties

It can be almost any color: white, red, pink, yellow, green, green, blue, lavender, black or brown. It can be transparent, translucent or opaque

4. Calcite in pH correction, Acid neutralizing

One of the greatest advantages of calcite is that in addition to being very economical, it is self-limiting – it only corrects the pH enough to reach a non-corrosive equilibrium. As the acidic water contacts the calcite media within the filter, the media is slowly dissolved, adding both beneficial calcium and magnesium ions to the water and bicarbonate ions that neutralize the acidity. Since these ions contribute to water hardness, a calcite filter will increase the water hardness. Accordingly, a water softener is sometimes recommended following a calcite neutralizing filter, especially where the original water hardness was already in excess of 5 grains per gallon. Since water chemistry and temperature vary, it is difficult to predict exactly how much harder the water will become. Most often, the hardness will increase 30-100 mg/l (2-5 grains per gallon).

5. Other applications of Calcite

Calcite is the main calcium mineral, fundamental in construction and the basis of cement. It is also important in the production of fertilizers, metals, glass, rubber and paints. The distinctive Icelandic spar, in which the birefringence is very pronounced, is used as a prism in polarizing microscopes and other optical devices.

This mineral also forms rocks that are used for decorative purposes, such as marble, striped granite and tuff. It is also the main ingredient of chalk that can be converted into chalk. For collectors, it is one of the best known and most frequently collected minerals. Most specimens are inexpensive, with the exception of those with a special crystal shape and size, or the classics.
