Static Screen for Wastewater Solid-Liquid Separation

Short Description:

The Static Screen is a compact, energy-free separation unit designed to filter suspended solids, floating matter, sediments, and other solid or colloidal substances from sewage and industrial wastewater.

It features a wedge wire welded stainless steel screen, which can be formed into an arc-shaped or flat filter surface. Wastewater is evenly distributed onto the inclined screen via an overflow weir. Solids are intercepted on the screen surface, while filtered water passes through the screen gaps. Meanwhile, the intercepted solids slide down to the lower end of the sieve plate under hydraulic force and are discharged, achieving efficient solid-liquid separation.

Using a Static Screen effectively reduces suspended solids (SS) and lowers the processing load for subsequent treatment steps. It can also recover valuable materials in industrial processes.

Applications

The Static Screen is widely used in various industries for wastewater pretreatment and resource recovery:

  • 1. Papermaking, pulp & fiber recovery — recycling fibers and removing solids.

  • 2. Slaughterhouses, tanneries — removing solids like fur, grease, pouches, and waste.

  • 3. Food & beverage processing — treating wastewater in sugar, wine, starch, beer, and malt production by removing plant fibers, hulls, scales, etc.

  • 4. Municipal sewage & small water supply — pretreatment for domestic or community wastewater.

  • 5. River dredging & sludge treatment — solid-liquid separation in environmental projects.

  • 6. Textile, petrochemical, printing & dyeing — recovery and pretreatment to remove suspended solids.

Key Features

High-Quality Screen Plates — Made from seam-welded stainless steel with high mechanical strength, non-deforming and crack-resistant.
Energy-Saving Operation — Utilizes gravity flow, requiring no power consumption.
Low Maintenance — Periodic manual flushing keeps screen gaps clear and efficient.
Model Selection — The unit does not tolerate shock loads; always select a model with capacity greater than the peak flow rate.

Working Principle

The Static Screen’s core component is an arc-shaped or flat wedge wire screen surface made of stainless steel rods. Wastewater flows evenly over the inclined screen through an overflow weir. Thanks to the smooth surface and wider gaps on the back, drainage is fast and clogging is minimized. Solids are retained and pushed downwards by hydraulic force for discharge, while clean water passes through, achieving reliable solid-liquid separation.
