Self-Cleaning Filters with wedge wire filter elements

May. 21, 2024

In industrial processes involving water/wastewater treatment or liquid filtration, maintaining liquid purity, water cleanliness and continuous liquid operation is crucial to ensure optimal performance and prevent equipment damage. Self-cleaning filters provide a reliable and efficient solution for filtration needs.

What are Self-Cleaning Filters?

Self-cleaning filters are designed to intercept suspended solids and particles in fluids, reducing turbidity and removing system impurities. 

A wedge wire filter is a filter element made of high-quality V-shaped wedge wires and support wires. It is installed in automatic self-cleaning filter housings, providing high-pressure resistance, corrosion resistance, and a large filter area. The uniform slot size ensures efficient filtration, making them ideal for use in automatic self-cleaning filter housings.

How do self-cleaning filters work?

The filtration process begins when the liquid enters the self-cleaning filter and passes through the wedge wire screen. As the liquid flows, dirt and particles accumulate on the inner screen surface, causing a gradual increase in differential pressure. When the pressure reaches a predetermined level, the control system triggers the self-cleaning process. A small portion of the filtered liquid returns to the filter body, and a motor-driven brush (scraper) cleans the screen, effectively removing contaminants. The drain valve opens, allowing for efficient impurities discharge.
