Product Descriptions
Vibrowest WESTON Static Screener | Static Liquid-Solid Separation Equipment
The Vibrowest WESTON Static Screener is a gravity-driven static separation system designed for high-efficiency liquid-solid separation with minimal operating requirements. Since this system contains no moving parts, motors, or vibration-generating mechanisms, it offers a long service life, very low maintenance needs, and operation without energy consumption. Static screeners are primarily used for separating solid particles from liquids, for filtration purposes, and for coarse separation prior to sedimentation, ensuring reliable performance within the process line.
General Description and Operating Principle
The WESTON Static Screener operates on a simple gravity flow principle. The liquid enters through the inlet nozzle and flows onto the inclined static screen element, moving downward without pressure loss. During this process, the liquid passes through the screen openings, achieving filtration, while solid particles that cannot pass through the mesh slide downward along the inclined surface and are collected at the solid discharge section. This static system:
• Contains no moving parts
• Requires no motor or vibration
• Consumes no energy
• Offers easy installation and simple operation
Static screeners can also be designed as pre-separation units that support mechanical or vibrating separators in more complex process lines.
Design Features and Construction
The structural design of the WESTON Static Screener is optimized to minimize installation space while maximizing flow efficiency. The inclined static screen element is manufactured with a specially curved profile to ensure optimal flow and rapid filtration. As the liquid flows over this surface, surface energy and gravity direct it toward the screen openings, while solids are retained on the surface.
Key construction features of the static screener include:
• Static and simple gravity-based separation design
• Easy-to-clean screen surface
• Minimal maintenance requirements
• Stainless steel construction options, depending on application
• Screen mesh configuration customizable according to process needs
Thanks to this design, static screeners significantly reduce routine maintenance requirements and minimize operator intervention compared to mechanical equipment.
Model Options and Dimensions
The WESTON Static Screener is manufactured in different sizes depending on the application. Standard models are generally offered in two main sizes:
• WESTON STATIC 24 - Ø 600 mm diameter model
• WESTON STATIC 48 - Ø 1200 mm diameter model
These two diameter options provide suitable solutions for both low-flow process lines and high-capacity liquid separation applications. Each model can be equipped with different screen mesh openings according to process requirements, allowing optimization of liquid flow performance.
Technical Performance and Capacity
The performance of a static screener is largely determined by liquid flow rate, screen opening size, and inclination geometry. Since the system is statically designed, capacity is directly related to flow rate. In general:
• Flow type: gravity flow
• Filtration method: static screen mesh filtration
• Size options: Ø 600 mm and Ø 1200 mm
• Solid separation: solids are retained on the screen and collected in the lower discharge section
Static screeners are suitable for coarse separation before filtration, removal of solids prior to water treatment processes, or applications requiring flow control.
Application Areas
The Vibrowest WESTON Static Screener is a flexible separation system suitable for a wide range of industries:
• Wastewater treatment plants - solid particle separation
• Agriculture and livestock sectors - organic waste and particle control
• Fruit and vegetable processing plants - pulp separation
• Fish and seafood processing - organic particle filtration
• Paper and pulp industry - water and fiber separation
• General processes requiring liquid filtration
These application areas allow the static screener to be used both as a standalone separation unit and as a complementary device integrated with Vibrowest vibrating or centrifugal separators.
Key Advantages
The main advantages of the WESTON Static Screener include:
• Minimal maintenance and failure risk due to the absence of moving parts
• Operation without any energy or power supply
• Easy installation, simple operation, and fast commissioning
• Effective solid separation in high-flow liquid applications
• Optimized pre-separation for water treatment and filtration lines
• Reduced operating costs
Thanks to these advantages, static screeners provide effective separation solutions at a significantly lower operating cost compared to traditional mechanical separation systems.
The Vibrowest WESTON Static Screener is a simple yet highly effective solution for industrial liquid-solid separation and filtration requirements. With no moving mechanical components, no energy consumption, and minimal maintenance needs, it serves as a reliable static separation unit in production lines. Its wide range of applications and two scalable model options make it suitable for a variety of process requirements.
