Product Overview:
Spiral sand-water separator is suitable for sedimentation basins in wastewater treatment plants and is a device used for treating sand-water mixtures in the wastewater treatment process.
Operating Principle:
The sand-water separator equipment typically has a spiral inclination of 25~30°. The sand-water mixture enters the equipment through the inlet pipe, and as it flows, the mixture is separated into sand particles and organic matter by the concentrating box at the top of the separator. The heavier particles, such as sand, settle at the bottom of the spiral trough due to gravity. Driven by the spiral blades, the material is lifted along the bottom of the inclined U-shaped trough. After leaving the liquid surface, it continues to move upwards. The moisture in the sand particles gradually flows back into the water tank through the gaps in the spiral blades, and the sand mixture dries out as it approaches the discharge point. Relied on gravity, the dried sand falls into other conveying devices. The supernatant liquid continuously overflows from the weir and flows back to the wastewater well, while the organic matter is carried along with the supernatant out of the overflow trough, achieving the separation of sand and water.
