Product introduction of Travelling Band Screen System
The travelling band screen system for wastewater intake filtration is an advanced center flow fine screening equipment designed for high efficiency solid-liquid separation.
It operates with a 2 mm filter belt hole diameter, ensuring precise interception of fibers, strips, and suspended solids that are difficult to remove using conventional screens.
The system delivers a separation efficiency of 80–97%, with a treatment capacity of up to 6500 m³/day, making it suitable for municipal sewage plants and industrial wastewater pretreatment systems.
Wastewater enters the center flow chamber and passes through both sides of the screen surface. Solids are intercepted inside the filter belt, while treated water flows out smoothly. Accumulated solids are automatically lifted and discharged through an intermittent mechanical movement system.
Working principle
The travelling band screen system operates using a center flow fine screening process with a 2 mm filter belt.
Working process:
This ensures continuous filtration with stable performance and minimal clogging risk.
