Product Description

Product Description

The Automatic Backwash Filter is an innovative self-cleaning marvel, meticulously engineered with an array of robust stainless steel filter elements. This cutting-edge filter is designed to deliver continuous, uninterrupted filtration around the clock, 24/7. Its remarkable efficiency lies in its ability to effectively eliminate solid particle contaminants from a diverse range of water and low-viscosity liquids, such as rolling emulsions. As a result, the liquid cleanliness is elevated to meet stringent system operation and downstream process requirements, ensuring the safeguarding of vital downstream equipment. This versatile filter finds its indispensable place in a multitude of industries, including oil & gas, metallurgy, marine filtration systems, water treatment, pulp & paper, and beyond.

 

Working Principle

In the intricate dance of filtration, the Self-Cleaning Backwash Filter for Process Water Filtration Needs showcases unparalleled efficiency. As the unfiltered liquid gracefully enters through the inlet, it begins its journey with 50% cascading into the central distribution tube, ascending to the zenith of the filter. There, it enters the filter elements from the apex. Meanwhile, the remaining liquid finds its path directly into the elements from the filter's base, ingeniously allowing simultaneous top and bottom entry. This orchestrated movement ensures a seamless passage through the filter elements, emerging purified and pristine from the outlet. As the system pulse is monitored, the moment the pressure drop or time aligns with the preset values, the automatic backwash procedure springs into action. A powerful gear motor animates the back-flushing rotation arm, meticulously cleansing each filter element in succession, all while maintaining continuous filtration. In this synchronized backwashing ballet, the upper end of the filter element is sealed by the sliding block, and the back-flushing valve graciously opens. The differential pressure, a silent conductor, orchestrates the reverse flow of clean filtrate, meticulously rinsing the inner surface of the filter element. Impurities, now dethroned, exit effortlessly through the sewage pipe, leaving the system ready for its next cycle of perfection.
