Characteristics

·The second generation of the aeration rotating disc is used
    The second generation of the aeration rotating disc is developed from the first generation disc, which is made from the procedure of glass fiber rotating disc. It overcomes several disadvantages such as the material composition is different at the different place of the disc, the disc can be separated into several layers easily and the quality can not be controlled steadily.

·Continues speed adjustment.  The amount of  the  dissolved  oxygen in the water is easly controlled, and has the good denitrogen result and low energy consumption.

·There are many discs on the axis. The number of the discs can be adjusted according to the water quailty.

·The effective depth of the water can reach up to 4.3m, the largest width of the single ditch is 12m.

·The special consideration is made for the connection of disc and  shaft, which can avoid slippage and break at the bottom of the disc for long time use.

·The type of motor reducer can be selected according to the command of clients.

·Be easy and convenient for operation and maintenance.
