Why Choose Our Wedge Filter Screen?
Our screens are manufactured using advanced winding technology, ensuring consistent slot tolerance and superior mechanical strength. The Johnson vee-wire design provides a continuous slot opening that resists clogging better than woven wire mesh or perforated plates. This makes it ideal for municipal sewage where solids content varies widely.
Key advantages include:
- Enhanced Flow Rate – High open area (up to 60%) reduces hydraulic head loss.
- Self-Cleaning – The wedge shape allows particles to slide off during backwashing, extending intervals between maintenance.
- Corrosion Resistance – Stainless steel withstands aggressive sewage chemicals, moisture, and hydrogen sulfide.
- Structural Integrity – Strong support rods and continuous wire welding ensure long-term stability under high-pressure conditions.
- Cost-Effective – Lower replacement frequency compared to other filter media, reducing total cost of ownership.
Applications in Municipal Sewage Treatment
This product is widely used in:
- Bar Screens – Primary screening to remove large debris and solids.
- Fine Screening – Secondary treatment for capturing smaller particles (0.5 mm).
- Sludge Dewatering – Filtering sludge prior to pressing or centrifuging.
- Effluent Filtration – Polishing treated water before discharge or reuse.
- Intake Screens – Protecting pumps and equipment from debris in water intake structures.
