The water (activated sludge mixture) of the secondary sedimentation tank flows into the diversion area through the water distribution hole pipe of the distribution channel, and then descends to the bottom of the pool through the baffle plate and the water baffle plate. The mud flows toward the center and rises in a plane after collection. In the process of converging and rising to the center of the pool, the clarified liquid is separated and flows back to the outlet channel at the side of the pool to form a large annular density flow, and the sludge settles to the bottom of the pool.
· high surface load;
· Reduce the surface area of the secondary sedimentation
tank and save the area;
· The number of equipment is reduced due to the reduction of
the number of secondary sedimentation tanks;
· Civil construction investment province (few tanks, no sludge
hopper);
· Fast sludge reflux to avoid sludge denitrification and
anaerobic floating;
· high solid load and high return sludge concentration;
· Reduce pool depth.




· Double-layer sedimentation tank
· Peripheral-feed and peripheral-take off clarifier
· Aerated grit chamber
· Horizontal-flow grit chamber

· Driving motor & speed reducer.
· Non-metallic driving sprocket (overload protection system)
· NH-78 non-metallic driving chain.
· Tightener device.


· Non-metallic driving sprocket (40T, NH-78 chain)
· Head shaft (non-metallic/metallic/stub shaft/telescoping)
· Non-metallic head shaft sprocket (23T, NMC-152 chain)
· Non-metallic driven sprocket (17T, NMC-152 chain)
· NMC-152 collector chain
√ Light weight of the collector chain, low elongation after water absorption.
√ Stable sprocket engagement and low failure rate during high loads operation.
√ The scraper flights have sufficient strength and stiffness.
√ The collector has low weight and energy consumption, being capable to working continuously for 24h per day.
√ Anti-abrasion material of components, long service life, low maintenance costs.
√ Low speed ensures effective sedimentation and removal of sludge, and avoids sludge disturbance & floating.
√ It can be applied to industrial wastewater treatment by unique material optimization of key components.
√ Suitable for various rectangular sedimentation tanks with a width of 1-12m.
