Product Description

 Multi-Cartridge Automatic Backflushing Strainer Filter For Chemical Industry


Product introduction 

Multicartridge automatic backwash filter is widely used to filter out the grain impurities in the high flow, high speed low viscosity liquid. it is a mechatronic equipment with good features of reasonable design, high efficiency of filtering, low running cost and successive filtering during the backwashing. It could be extensively applied in the fields like metallurgy, chemical industry, power, injection water of the oil field and environmental water treatment.


Process description 

When the liquid flows from the inner side of the strainer to the outer side, the solid grain was held in the inner side of the strainer. With the increase of the pollutant, the pressure difference between the polluted side and the clean side is also growing. When the pressure difference reaches the setted data, the automatic backwashing will start to work.

Features and Benefits:

Automatic Monitoring
This filtration system is automatically monitored both on elapsed time since the last backwashing and pressure differential. This dual monitoring offers the user the flexibility to assure that filter operation is maintained with high efficiency, low pressure drop and consistent high quality produced water.

Long-Lasting Construction
The Automatic Backwashing Screen Filter is built for years of durable, trouble-free service. The filter canisters are constructed of carbon steel, which is fusion epoxy lined as a standard feature.

The carbon steel manifolds and the cast iron backwash valve are also fusion epoxy lined. The permanent stainless steel filter screens require no maintenance. In addition to the automatic backwashing cycle, the filter canisters and screens have no internal moving parts to wear out, break down or replace.




working principle


Automatic Backwashing Screen Filter provides the ultimate in high-rate screen filter performance. Powered by source line water pressure, the filter’s patented backwashing valve system produces a reverse flow to flush the system of entrapped contaminants.


During the brief backwashing cycle, a portion of the clean water produced by the system is diverted to the filter unit undergoing backwashing. This reverse flow of filtered water frees contaminants from the filter screens. Each filter canister is sequentially backwashed until the entire system is cleaned.










Design feature of the multi— Core self— Cleaning filter 

1.The filter adopts the selfcleaning internal mechanical structure to realize the automatic backwashing function. It could clean the impurity accumulated on the SS cartridges completely,There is no dead angle for washing and no flux attenuation so that it realize high filtering efficiency and long service life

2. The filter housing is made of 304, 316L stainless steel with high strength, high degree and strong corrosion-resistance. The highest filteration degree could be 50 micron.

3. The filter with few wearing parts, no consumable parts, low maintenance cost. simple operation and management

4. The filter control system is of sensitive response and precise operation. The backwashing pressure difference and the time could be adjusted flexibly according to the different water source and filtration degree.
