CTX offers a range of filters that retain particles of dirt, thus keeping water transparent and crystalline.
Particles in suspension in the water are retained as they pass through a sand filter media. Once the filter has removed impurities, reaching a pre-defined level, it can be regenerated through backwashing. The quality of the filtration depends on several parameters, including the shape of the filter, the height of the filter media, characteristics and grain size of the filtering mass, speed of filtration, etc.
