SAND FOR FILTRATION
It is a siliceous spherical sand that is used for water filters in swimming pools or purifiers to retain the solid particles suspended in the water. Sand filtration is a well-proven and reliable method that enables high levels of removal to be achieved.
The sand is ready for use and is dosed according to the volume of the filter used. In order to obtain correct filtering, replace the sand periodically.
SAND FOR SANDBLASTING
Quartz sand is also used to prepare a surface before primarization, by a mechanical process that exploits the highly abrasive capacity of the compound. During sandblasting, the individual grain of sand is projected at high speed onto the surface to be cleaned, loosening the layer to be removed and pulverising it.
