Wedge wire filter tube (also known as wedge screen tube, V-wire filter tube) is a filter element made of trapezoidal cross-section metal wire (or other materials) through precision welding or winding. Its unique wedge-shaped gap design makes it widely used in various industrial fields. The following are its main uses and characteristics:
Water treatment and environmental protection field
Sewage treatment: used for pretreatment of sewage plants (such as grid filtration), effluent filtration of sedimentation tanks, MBR membrane bioreactors, etc., to remove suspended matter and impurities.
Drinking water filtration: used as well as pipes and filter pipes for coarse filtration of groundwater or river water to prevent sand and gravel from entering the water supply system.
Industrial wastewater treatment: filters particulate matter in wastewater from chemical, papermaking, food, and other industries.
Petroleum and natural gas industry
Sand screen: used as a "sand screen" in oil wells or gas wells to prevent formation sand from entering the oil production pipeline while allowing oil and gas to pass through.
Downhole filtration: used for proppant retention (retaining fracturing sand) in horizontal wells and fracturing wells.
Mining and Metallurgy
Slurry Filtration: Separation of slag and liquid during the ore dressing process, such as tailings dehydration and thickening tank filtration.
Coal washing plant: Filter coal slurry water and recover coal particles.
Chemical and Food Industry
Chemical Process Filtration: Filter corrosive liquids or high-temperature media (requires acid and alkali-resistant materials such as 316L stainless steel and Hastelloy).
Syrup and juice filtration: Food-grade stainless steel wedge-shaped wire tubes are used to remove pulp fibers or impurities.
Agriculture and Irrigation
Drip irrigation system: As the core component of the filter, it prevents dripper clogging.
Drainage system: Used for anti-clogging filtration of farmland or greenhouse drainage pipes.
High-precision filtration: Uniform gaps (usually 0.02 mm- 3 mm adjustable), not easy to clog.
High strength: The wedge-shaped wire structure is resistant to high pressure and impact, making it suitable for harsh environments.
Self-cleaning: The V-shaped gap design can reduce particle clogging, and reverse flushing is easy to recover.
Corrosion resistance: The material can be selected from stainless steel, titanium, plastic (such as PP), etc., to adapt to different media.
Wedge wire filter tubes have become irreplaceable filtration components in many industrial processes due to their high efficiency, durability, and wide adaptability.
