PH increasing filter media Imerys Calcite, 15,6ltr / 23kg bag

High quality Calcite is a naturally occurring calcium carbonate filter material. Calcite is used to increase the pH of the source water before feeding it to the deferrization filters. The filter loaded with Calcite is usually installed before the installation of the water softener, since the material increases the hardness of the water. The price is indicated for a bag (15.6 l).

The advantages of Calcite filter media are natural origin and absolute harmlessness of water;
- self-limitation of the pH level when the optimal value is reached;
- high efficiency in preliminary water treatment to remove manganese and iron;
- calcite is suitable for conditioning a liquid with calcium ions without the use of dosing equipment for water with low mineralization;
- with a small drawdown and work intermittently, calcite increases the pH of the water.
- unlike analogs, water, after passing through Imerys calcite, does not become cloudy

APPLICATION AREA
Not limited. An obstacle to the use of Calcite can only be the requirement for excessive water softness. In the absence of these, Calcite can be used in any water treatment systems.
MAINTENANCE AND OPERATION
The use of Calcite suggests that periodic flushing of the filter bed will be required. This avoids the compaction of the upper layer of the load, stratification of the fraction and its cementation. In addition, at a low level of water hardness, depending on its chemical-organic composition and water flow rate, it is necessary to replenish the supply of depleted filtering bedding. Calcite is the best choice for domestic and domestic water treatment systems that require water hardness increase and purification. In combination with other water treatment systems, this allows you to achieve high results with adequate costs for equipment and filtering materials.
