Qinhuangdao Shi Ji Yuan Water Treatment Technology Co., Ltd—

Advanced feature compared with foreign like products
The domestic water treatment market is besieged with many brands under the name of “automatic backwash” differential pressure filter (also called automatic cleaning filter) , which, whenever imported or made in China, are technically the same; the so-called “automatic backwash” does not actually refer to automatic backwash and there are only designed with one set of filth collector in the inside wall of filter screen, in which the suspending impurities are sucked into drain pipe with the help of self water pressure, while the impurities securely attached to filter screen or blocking the channel of filter screen can’t be removed and will be accumulated to finally make filter screen fail to permeate water and affect its service life. Even though some products are made with cleaning brush, they can only remove impurities attached to filter screen and cannot do anything about removal of impurities in the channel, even more, they may make these impurities pass through filter screen to enter water-producing side to affect the water quality. The restrictions imposed by the cleaning mode result in failure in producing higher filter fineness by these products as well as make the dream of so-called high fineness unrealized.
The launch of Shi Ji Yuan brand double intelligent pressure differential filter fundamentally solves problems concerning the technical restrictions and makes breakthroughs in original self-suction cleaning mode by means of unique internal mechanical structure and the exquisite combination of external high pressure backwash and internal self-suction discharge for cleaning to achieve efficient and thorough cleaning without non-cleaning areas so as to greatly lengthen the service life of filter screen. Meanwhile, fine filter screen firstly adopts 316L stainless steel sintered mesh to provide assurance to the mechanical strength and filter fineness with maximum filter fineness reaching as high as 2mm, which is beyond the reach of the like products.
