1. Purpose
BFD float type water purifier is a specialized equipment for sewage treatment, suitable for various intermittent circulation activated sludge treatment systems. During the drainage stage, the treated supernatant can be removed from the surface or installed in the "regulating settling tank" to enter the biological reaction tank at a constant flow rate, achieving good and stable treatment effect. BFD float type tailwater purifier is used in small circulation activated sludge treatment systems with a treatment capacity of less than 200m/h
2、 Model Description

3、 Characteristics
1. Simple structure and easy maintenance
2. No power required, relying on buoyancy and self weight for lifting and lowering
3. Adjustable drainage volume and simple operation
4. Easy to achieve automatic control
5. When the eye qi is thick and thin, it rises to prevent sludge from flowing into the drainage pipe
4、 Construction and working process
The BFD floating type tailwater device consists of a float, a water inlet, a sliding rod frame outlet hose, an outlet bamboo flange and other components, which do not require power. During the gas and sedimentation stages, the water device floats on the water surface and is in a standby state. The clear water accumulated in the outer outlet hose forms a water seal to prevent dirty water from entering the outer pipe. The electric valve opens and the supernatant in the pool is discharged. As the water level drops, the float slowly slides down in the guide rod of the bracket. When the water level drops to the lowest level, the electric valve is closed and the drainage is completed. The equipment appearance and technical parameters are shown in the chart
