Backwash Filter

A backwash filter is a self-cleaning filtration device designed to remove impurities and particles that accumulate on the filter medium through reverse flow, thereby restoring filtration efficiency and extending the filter's service life. This filter can automatically carry out the cleaning process without the need for manual intervention, ensuring the continuous and stable operation of the filtration system.Specifically, when the backwash filter is working, it first intercepts solid particles,
suspended solids and other impurities in the liquid or gas to be treated in the filter medium (such as filter screen, filter material, etc.) through the normal filtration process, so that the clean fluid passes through and flows out.

Backwash filter as an automatic cleaning filter equipment, has a series of advantages and disadvantages. The following is a detailed summary:
Efficient filtration	The backwash filter can effectively remove impurities, particles, suspended matter in the liquid or gas, providing high-quality filtration effect to ensure the quality of the product and the smooth progress of the process.
Self-cleaning function	It has an automatic cleaning function, through the reverse washing mechanism, regularly remove the accumulated pollutants inside the filter, reducing the frequency and workload of manual maintenance, while extending the service life of the filter.
Continuous operation	while backwashing, it does not affect the normal operation of the system, ensuring the continuity of the production or use process.
Long service life	Due to the timely cleaning of dirt, the wear and corrosion of the filter elements are reduced, thus extending the overall service life of the filter.
Low pressure loss	The design is reasonable and the pressure loss generated during the filtration process is small, which helps to reduce energy consumption.

Product Details

Working Principle

The backwash filter works as an automatic and cyclic process that cleverly combines filtration with self-cleaning. In the normal filtration stage, when the liquid or gas to be treated passes through the filter medium, the impurities are effectively
intercepted and trapped on the medium, and the clean fluid is smoothly drained. Over time, impurities accumulate gradually, resulting in a decrease in filtration efficiency and an increase in pressure differential. At this point, the filter's built-in monitoring system automatically detects this change and triggers the backwash procedure. In the backwash phase, the filter closes the channel of normal filtration and instead introduces the cleaning fluid for backwashing. This reverse flow design strongly scour the filter medium, stripping the attached impurities and discharging them with the cleaning fluid. After the cleaning is complete, the filter automatically returns to the normal filtering state and continues to perform its filtering task. The whole process is automated without manual intervention. The backwash filter ensures long-term and stable filtration performance through a continuous cycle of this filtration and self-cleaning process. This design not only improves the filtration efficiency, but also greatly reduces the cost and time of manual maintenance, making backwashing filters widely used in industrial production and water treatment and other fields.
