Wound Polypropylene Micron Filters

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 Dref Spun 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.


MMP is the largest manufacturer of the wound PP filters in India. The Hydrowound filters use the PP yarn manufactured by a superior technology. The yarn is fibrous and has about 40% higher air volume compared to conventional yarn. The filtration takes place by "absorption technology".

This provides for the advantages of:
  • lower pressure drop
  • increased efficiency and
  • higher dirt holding capacity.

Micron Rating

MMP Hydrowound filters are offered in standard micron ratings of 0.5, 1, 5, 10, 25, 50, 75 and 100. On request, customised micron rating can also be provided. The filters are of nominal rating with an efficiency of 88 - 90%.

Alternate Media

On customer request, the wound type filters can be provided with alternative filtration, besides polypropylene media as below,
