Characteristics and simplified management of tube settler
- Jan 30, 2019 -

Inclined tube settler characteristics
1. The wet circumference is large and the hydraulic radius is small.
2. The laminar flow state is good and the particle sedimentation is not disturbed by the flocculation.
3. When the length of the inclined pipe packing pipe is 1 m, the effective load is designed according to 3-5 tons/m 2 ·. The V0 is controlled in the range of 2.5-3.0 mm/sec, and the effluent water quality is the best.
4. The honeycomb inclined pipe is used at the water intake. When the pipe length is 2.0 to 3.0 meters, it can be safely operated in the high turbidity of 50-100 kg/m3 mud sand content.
5. The inclined tube sedimentation tank is used, the treatment capacity is 3-5 times of the advection sedimentation tank, and the clarification tank and the pulse clarification tank are 2-3 times.

The aeration intensity of the inclined tube settler is lower than that of the activated sludge method, and sludge backflow is not required, so power consumption can be reduced and management can be simplified. The amount of sludge is small, which reduces the amount of post-treatment work such as sludge dewatering. The resulting sludge has good sedimentation and is beneficial to the removal of suspended solids in the latter stage.
