These are popular water filters that have a continuous, diagonally interlocking weave over a supporting core. The most popular media used for these filters is a polypropylene(PP) yarn over a PP supporting core. The winding provides tapered filter passages of controlled size and shape. These filters work on the principle of depth filtration, offering a gradual rise in pressure drop across the life of the filter. The filter equipment functions independently by simply fixing it on the nozzle of any pipeline in the industries for getting clean drinking water.
