Rotary Solid Liquid Separator for Wastewater Treatment SS304
Rotary solid liquid separator is a high-efficiency mechanical bar screen designed for continuous wastewater pretreatment. It uses a rotating rake chain made of ABS, nylon, or stainless steel to intercept and remove solid debris from liquid flow. With self-cleaning function, automatic operation, and corrosion-resistant materials, it ensures stable performance under complex conditions. Suitable for municipal and industrial wastewater treatment plants, it achieves over 95% solid removal efficiency with low energy consumption and reliable operation.

Product introduction of Rotary Solid Liquid Separator
Rotary solid liquid separator, also known as rotary bar screen, is installed in wastewater channels for continuous solid-liquid separation. The rake chain operates at a speed of 2 m/min and can be installed at angles of 60°–80° depending on site conditions.
As wastewater flows through the channel, rake teeth lift solid debris upward. At the top, a self-cleaning mechanism removes trapped materials, ensuring continuous operation without clogging.
The system supports automatic control via liquid level difference or timer, making it suitable for unmanned operation in modern wastewater treatment plants.
Working principle
Step 1: Wastewater Inflow
Wastewater enters channel and flows through submerged rake section.
Step 2: Solid Capture
Rake teeth capture floating and suspended solids from water.
Step 3: Upward Conveying
Rake chain lifts debris upward at controlled speed (2 m/min).
Step 4: Self-Cleaning Process
At top rotation point, debris is automatically removed by gravity and brush system.
Step 5: Discharge & Separation
Separated solids fall into collection bin, while water passes through gaps.
