Pressure filtration equipment NPF Series

There are two types of NPF Series: “dual-media type,“ which uses anthracite and sand as filter media, and “multi-media type“ adding garnet to the above two media.
Especially, filter for the multi-media type is designed so that high quality of product water can be obtained without flocculant.
Furthermore, by using a special filter medium, it is possible to add a function of oxidizing and removing iron and manganese dissolved in water.
In the cleaning process after water supply for a certain time, it is effective to conduct surface layer cleaning and air backwash in addition to the normal water backwash, for obtaining better product water quality at the next water supply.
