1、 Overview of Fiber Rotary Filter

Process diagram of fiber rotary filter

The operating status of the fiber rotary filter includes filtration, backwashing, and sludge discharge.

Filtration: The sewage flows into the filter tank by gravity, causing the filter disc to be completely submerged in the sewage. Install a water distribution weir in the filter tank to ensure uniform water distribution and low disturbance of incoming water. The sewage is filtered through a filter cloth, and the filtered liquid is collected through a hollow pipe before being discharged from the filter tank through an effluent weir. During the cleaning process, filtration is still ongoing. Therefore, the filtering process is continuous throughout the entire operation.

Backwash: Part of the sludge in the filtration is adsorbed onto the fiber filter cloth, gradually forming a sludge layer. As sludge accumulates on the filter cloth, the filtration resistance of the filter cloth increases, and the water level of the filter gradually rises. The pressure sensor in the filter tank monitors the liquid level changes in the tank. When the liquid level in the tank reaches the cleaning set value (high water level), the PLC can start the backwash pump and begin the cleaning process. The backwash time and cycle can be adjusted. The sludge on the filter cloth is discharged into the factory drainage system through a reverse suction device and a backwash water pump. During backwashing, the filter can continuously filter.

Sludge discharge: The fiber disc filter has a bucket shaped bottom under the filter disc, which is conducive to the collection of sludge at the bottom of the tank. The sedimentation at the bottom of the sludge tank reduces the amount of sludge on the filter cloth, which can prolong the filtration time and reduce the amount of backwash water. After a set period of time, the PLC starts the sludge discharge pump and returns the sludge to the factory drainage system through the perforated sludge discharge pipe at the bottom of the pool. Among them, the interval and duration of sludge discharge can be adjusted.

In addition, when the treatment system before the filter fails, the sludge discharge system can be activated to clear the filter

3、 Vertical fiber filter

The operational status of the vertical fiber filter includes filtration, backwashing, and sludge discharge.

Filtration: The sewage flows into the filter by gravity, and there is a water distribution weir in the filter. The filter cloth adopts a fully submerged type, with sewage entering through the outside of the filter cloth, and the filtered liquid collected through a lower air pipe. It flows through the outlet weir by gravity and is discharged from the filter tank. The entire process is continuous.

Backwash: During filtration, some sludge is adsorbed onto the outside of the filter cloth, gradually forming a sludge layer. As sludge accumulates on the filter cloth, the filtration resistance of the filter cloth increases, and the water level of the filter gradually rises. When the liquid level in the pool reaches the cleaning set value (high water level), the PLC can start the reverse suction pump and begin the cleaning process. During backwashing, the filter can continuously filter.

3 sludge discharge: The fiber filter has a bucket shaped bottom under the filter plate, which is beneficial for the sludge at the bottom of the tank

The collection. The sedimentation at the bottom of the sludge tank reduces the amount of sludge on the filter cloth, which can prolong the filtration time and reduce the amount of backwash water. After a set period of time, the PLC starts the sludge discharge pump and returns the sludge to the factory drainage system through the perforated sludge discharge pipe at the bottom of the pool. Among them, the interval and duration of sludge discharge can be adjusted.
