Sand Water Separator
Item No.: | AA/AB Series |
AA Series-Closed Swirling Desander
AB Series-Sprial Sand-Water Separator
1. Structure and Principle
Desander is based on the principle of centrifugal force, the water from the inlet into the device. It is resulting in a strong rotation motion under pressure effect. The centrifugal force, the role of the buoyancy, and fluid drag force can generate a different loading. Due to the different density of sand and water, the low density of water rising out of the exhaust outlet, high density sand is discharged from the bottom outlet, so as to achieve the purpose of grit removal. The product is mainly composed of driving device, stirring mechanism, absorbing part of the sand system, and electric control components.
2. Purpuse
AA
- Sand-water separating for urban sewage,l industrial wastewater treatment integrated plant.
- Sand-water separating for river water, well water, lake water, purification plants.
- Sand-water separating for industrial minerals, coal washing water and other areas.
AB
- Sand-water separator for ultra-high sand content of wastewater.
- Post treating collocation with a grit chamber of sewage treatment plant.
- Post treating collocation with a closed desander or open grit chamber.
3. Features
The high sand removal efficiency is reached under the centrifugal and gravity by using tangential feeding water. They are small size, high surface loading, and large treating capacity, grit process not affected from hydraulic impact.
4. Specification and Functions
Sewage treatment plant with a grit chamber, sediment separation effect is good. The closed or open grit desander is used for special high-performance separator with high sand content.
