Working Principle
1. Inlet: Sand-laden wastewater enters the separator through the inlet.
2. Separation: As the wastewater flows inside the separator, sand particles settle to the bottom due to gravity.
3. Transport: A screw conveyor transports the settled sand from the bottom to the discharge outlet.
4. Discharge: The separated clean water is discharged from the outlet, either moving to the next treatment stage or being released directly.


Applications
1. Sewage Treatment Plants: Used in the preliminary treatment stage to remove sand and solid particles from wastewater.
2. Industrial Water Treatment: Applied in treating industrial wastewater to separate solid impurities.
3. Construction Sites: Used to treat sand-containing wastewater generated during construction activities.
4. Mining and Metallurgy: Employed in treating sand-containing wastewater from mining and metallurgical industries.


Maintenance and Care
1. Regular Inspection: Periodically check the wear and tear of the screw conveyor and the interior of the separator, replacing worn parts promptly.
2. Cleaning and Maintenance: Regularly clean accumulated sand and debris inside the separator to keep the equipment clean.
3. Lubrication: Regularly lubricate the bearings and transmission components of the screw conveyor to ensure smooth operation.
The spiral sand-water separator plays a crucial role in sewage treatment and industrial water treatment, effectively improving water quality and reducing the impact of solid impurities on subsequent treatment processes.
