ZWN series micro filter adopts 15-20 micron ventage filter process which terms as micro filtering. Micro filtering is a kind of mechanical filtering method. It is applied to maximally separate the micro suspended substance (pulpfiber) existing in the liquid and realizes separation of the solid and liquid. It is widely applied to the sewage filteration of papermaking, textile, printing and dyeing, chemical industry and foodstuff. It is especially applied to the treatment of papermaking water so as to achieve the aim of closed cycle and reuse.
