Wedge wire filter element is a type of filter element welded from stainless steel wedge wire and stainless steel support strip, with a smooth surface and uniform gaps, belonging to the surface filtration form. Wedge wire filter cartridges are widely used in fluid filtration in various industries, especially in automatic backwashing, scraper self-cleaning, scraper self-cleaning, and suction self-cleaning filters.

Wedge wire filter cartridges are widely used in the following fields:

1. Petrochemical industry: catalytic reactions, hydrogenation desulfurization, styrene dehydrogenation, ammonia conversion, etc.

2. Sewage treatment and flood control system: water source inlet, basement supply, carbon and resin retention, mineral extraction softening, and ion exchange.

3. Mineral processing, papermaking, etc.: screening, coal drying, starch filtration, pulp and plant fiber filtration, beverage filtration, etc
