Arena silex 25 kg- granulometry 0.40-0.80

A sand filter is the most important accessory that should be present in any pool where it is necessary to retain impurities that are smaller than 20 microns. To do this, it is necessary to condition it with a 25 kg silex sandbag and a grain size between 0.40 and 0.80 to retain suspensions below the maximum required. The system is simple: water passes through the suction nozzles placed in the pool and passes through the filter that retains all contaminating particles. once purified, the water returns to the pool completely pure. Silica sand, in combination with oxygen, forms a water-insoluble molecule, with absorption capacity and is widely used as a filter bed for impurity retention and water purification. Healthy water.
