【 Use】
Rotary Decanter is developed by Jinyuan Group on the basis of digesting foreign technology. It is specially designed for sequencing batch biological treatment system and has good hydraulic and mechanical properties. It can realize the laminar flow state of the water entering the outlet weir during the water skimming process, and the water skimming speed is stable and adjustable, so that the water output remains unchanged. It is the key equipment of the circulating activated sludge process.
[ Model meaning ]

[ Working process ]
During the aeration and sedimentation stages, the Decanter is located above the highest water level in the main aeration zone. When skimming, descend below the water surface for skimming, and when the water level drops to the lowest level, the Decanter returns to its original position.
【 Characteristics 】
● Decanter realizes automatic speed change during operation, and has a wide speed control range. The operation of the equipment keeps pace with the falling water level, and the falling speed is uniform. The running speed during water skimming can be selected according to different water quality.
● The frequency converter of the electric control system is installed in the local control box, which can be controlled manually on the spot and can be automatically controlled by receiving the signals from the central control room.
● The whole process of water discharge can prevent the scum on the water surface from entering the water outlet weir.
● The height of the outlet weir can be adjusted on site according to the needs of the outlet.
● The underwater rotating parts have good sealing performance, the sealing ring has a long service life and is easy to replace, which can ensure that the water quality of the effluent is supernatant.
● Limit control is implemented during Decanter operation. to protect the institution from damage.
● The drive mechanism is stable and reliable, with low power consumption and low operating cost.
● The whole machine is compact in structure, easy to operate and easy to maintain.
