Wedge wire filter/metal wound filter is widely used in oil, gas, well sand control, and applications in the chemical industry, environmental protection, and other industries are especially important. It is the most widely used filter screen tube in various oil and water resource recycling and collection resin filter media links.
The wedge wire filter adopts the world’s most advanced full-wound welding production process. It is made of special stainless steel trapezoidal (wedge) wire windings welded on a group of longitudinal support rods arranged in a circle, thus ensuring its strength and service life.
The wedge-shaped filter has accurate gap size and high filtration precision; it has a solid structure, high-temperature resistance, corrosion resistance, and good mechanical properties and can be used for filtration of various media.
The use of full-process welding not only ensures the strict continuous integrity of the product but also enables it to form an ideal gap size. Compared with the welding process commonly used in China, the all-welded wedge-shaped wire-wound screen tube, water filter tube, water cap, water distributor, resin catcher, and screen plate have smooth tube surface, no production edges and corners, and no burrs. The gap is uniform and does not leak grease.
Recycling water has a positive impact on the environment and saves companies a lot of money. Water circulation screens (wedge wire filters) are a cost-effective self-cleaning solution to water circulation problems. Whether you want to reuse wastewater to reduce costs or reduce your environmental impact, wedge wire filters can meet your needs.
Wedge Line Filter Features:
- High mechanical strength, able to withstand the enormous pressure difference
- The filtration gap is uniform, forming a relatively uniform filter cake that is conducive to backwashing and regeneration.
- The wedge-shaped filter gap can improve the backwash regeneration capacity.
- Pressure, temperature, aging, and corrosion resistance can be adapted to various fluids.
- The metal wedge-shaped mesh filter element adopts metal wedge-shaped wire mesh (Johnson tube) as the filter element, which has high mechanical strength, high-pressure difference resistance, easy backwash regeneration, etc.
Benefits of using a wedge line filter:
Durable even with small holes, from 0.1mm to higher, self-cleaning, and cost-effective.
Industries that use wedge wire filters include:
Industrial toilets and factories
Facilities that have access to sewers must comply with waste regulations or may require reduced sewer bills. The wedge-shaped screen effectively removes moisture from solids, is highly durable, and removes the finest particles. Since the screen is non-mechanical, downtime is significantly reduced, making wedge wire filters the most cost-effective option.
Rainwater harvesting is becoming more and more popular. It is collected, filtered, pumped, and stored in tanks, and the water is reused for washing, cleaning, irrigation, and other livestock needs. Rainwater harvesting can save customers a lot of water bills and improve the environment. Wedge wire filters are used in the initially collected rainwater; they are durable in all weather conditions and can filter acceptable debris.
Road and footpath sweepers
Road sweepers are designed to lift everything from the road, stones, paper, trash, etc. Older filter systems used braided wire or perforated plates, which were flawed because they would continually clog, rendering the screen ineffective. Now, thanks to the self-cleaning properties of the wedge-line filter, it allows the sweeper to recycle dirty water so that clean water can be reused without filling the tank with clean water.
