Reliable Filtration Solutions for Industrial & Municipal Water Treatment
In modern water treatment systems—from desalination to municipal wastewater recovery—filtration efficiency directly impacts operational costs. Johnsonslot offers high-performance wedge wire components designed to eliminate clogging and provide superior backwashing performance. Our V-wire technology ensures consistent flow rates and long-term structural integrity in the harshest environments.
Our Core Water Treatment Products:
Filter Nozzles & Underdrains: Designed for sand filters and ion exchange vessels. Our stainless steel nozzles provide much higher strength and chemical resistance than traditional plastic alternatives.
Resin Traps: A critical safety component for ion exchange systems. Our resin traps feature strict slot opening tolerances to prevent the loss of expensive resin beads during backwashing or underdrain failure.
Passive Intake Screens: Environmentally friendly solutions for lake or river water abstraction. These screens protect aquatic life while ensuring a steady, debris-free flow for downstream processing.
Why Water Engineers Trust Johnsonslot?
We specialize in Self-Cleaning Wedge Wire Filter Elements. By utilizing a two-point contact V-wire design, we reduce maintenance frequency and energy consumption. All components are available in SS304, SS316L, or Duplex Stainless Steel to meet your specific corrosion resistance requirements.
Water & Wastewater Treatment Screens | Wedge Wire Intake & Filtration Systems
1. Core Functions
Efficient Contaminant Interception:
Utilizes V-shaped gap design (adjustable 0.02-5mm) to capture hair, sand, oil clots, and other pollutants with >95% filtration efficiency.
Self-Cleaning & Anti-Clogging:
Reverse flushing easily dislodges trapped debris, reducing manual cleaning frequency by 75% compared to traditional filters.
Wedge wire screen plate can be used for sewage treatment, mud water filtration. In the sewage treatment, the wedge wire screen plate can be used to filter and separate the solid impurities in the sewage, such as suspended matter, sediment, etc., To improve the sewage purification efficiency and improve the water quality.
2. Four Major Advantages
Durability:
Made of corrosion-resistant metals (e.g., stainless steel, titanium alloys) for a 10+ year lifespan.
Cost Savings:
No frequent media replacement required, cutting maintenance costs by 60% vs. woven screens.
Versatility:
Handles domestic sewage to harsh industrial wastewater (e.g., electroplating, chemical plants) with 30% efficiency gains in pollutant removal.
Eco-Friendly:
Minimizes water usage for flushing and supports energy recovery systems for sustainable operations.
SLOT product portfolio covers a range of water and wastewater treatment processes, with a focus on head works and screens for liquid and solid separation for the most diverse industrial applications.
3. Typical Applications
Domestic Sewage:
Protects pumps by intercepting debris (e.g., plastics, textiles) in municipal systems.
Industrial Wastewater:
Food Processing: Separates fats/oils efficiently.
Chemical Plants: Filters toxic particles (e.g., heavy metals).
Seawater Treatment:
Used in Middle Eastern desalination plants for corrosion-resistant pre-treatment, extending equipment life.
Reliably separating inflow water and wastewater from coarse solids is crucial for all subsequent treatment processes. This avoids blockages and obstructions in downstream biological or physical processes and strain on the plant.
The wedge wire screen acts as a "wastewater guardian"—durable, low-maintenance, and a cost-effective solution for modern filtration challenges.
