Backwash filter is a kind of precise equipment that uses filter screen to directly intercept impurities in water, remove suspended solids and particles in water, reduce turbidity, purify water quality, reduce system dirt, bacteria, and algae, rust, etc., so as to purify water quality and protect the normal operation of other equipment in the system.
The backwash filter water enters the self-cleaning filter body from the water inlet. Due to the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and automatically discharge the signal to the blowdown valve.
The operation and control of the backwash filter do not need any external energy, and can automatically clean, filter, and blowdown automatically.
The operation and control of the backwash filter do not need any external energy, and can automatically clean, filter, and blowdown automatically.
The filtration accuracy can reach 10-3000 μ m; the working pressure of the backwash filter can reach 1.0-1.6mpa; the flow rate of a single set is 4-4160m & sup3) / h.
The backwash filter can be installed vertically, horizontally, and inversely in any direction and in any position. It can be used for water filtration in industries, agriculture, municipal power, electronics, medicine, food, printing and dyeing, construction, steel, metallurgy, papermaking, and other industries.
Type of metal filter element for backwash filter: Wedge Wire Filter.
Manufacturing process of backwash filter
- The structure and function of the backwash filter are designed, and the structure is compact.
- The anti-corrosion performance of high – strength ductile iron material for the backwash filter is good.
- The special filter element design and manufacturing technology of the backwash filter ensure that the high-precision filter element will never wear, the pressure test will never deform, and the factory precision test can meet the user’s requirements.
- The coarse and fine filter screen of backwash filter adopts stainless steel welded mesh, and the screen plate and screen mesh form the internal and external double-layer structure; because the active cleaning method is adopted for the filter element, its anti-interference ability is enhanced and the cleaning is clean, which is especially suitable for poor water quality conditions.
