In industrial water treatment—whether it's municipal supply, desalination, or wastewater recovery—system uptime is everything. The biggest enemy of efficiency is "blinding" (clogging). This is why engineers are moving away from traditional mesh and upgrading to self-cleaning wedge wire filter elements.
At Johnsonslot®, our water treatment components are engineered to provide maximum filtration precision with minimum maintenance intervention.
Unlike woven wire mesh where particles can get trapped in the overlaps, the wedge wire screen features a two-point contact V-wire design. Since the slot widens inwardly, any particle that passes the surface will flow through without getting stuck.
Better Backwashing: In automatic backwashing systems, the smooth surface and V-shape allow the cleaning cycle to be shorter and more effective, saving thousands of gallons of flush water annually.
Lower Pressure Drop: High open area means your pumps work less, significantly cutting energy costs.
One of the most critical long-tail applications in water treatment is the Resin Trap. In ion exchange and carbon filtration systems, a failure in the underdrain can lead to the loss of expensive resins. Our resin traps act as a "safety net":
High Strength: Designed to withstand full line pressure in the event of a primary system failure.
Precision Slotting: With our strict slot opening tolerance, we ensure even the smallest resin beads are contained.
| Feature | Wedge Wire Element | Woven Mesh / Plastic |
|---|---|---|
| Self-Cleaning Ability | Excellent (V-wire geometry) | Poor (Subject to blinding) |
| Structural Life | 10+ Years (Stainless Steel) | 1-3 Years (Fragile) |
| Chemical Resistance | High (SS316L / Duplex) | Variable |
For large-scale water abstraction from rivers or lakes, passive intake screens using wedge wire protect aquatic life while providing a constant flow of debris-free water. The low "face velocity" of our designs is compliant with environmental regulations worldwide.
Whether you are designing a new desalination plant or looking for replacement filter nozzles for a sand filter, Johnsonslot® provides the technical expertise and manufacturing precision your project requires.
