What are the application fields of cloth filter?

Do you know the application fields of the cloth filter? The cloth filter can be widely used in the filtration after the precipitation, clarification and air floatation process, such as:

Municipal sewage advanced treatment (Municipal sewage treatment plant level 1 B is upgraded to level 1 A);

·Industrial production water treatment filtration (chemical plants, paper mills, printing and dyeing plants, auto parts processing plants, etc.);

·Circulating water treatment filtration (swimming pool water circulation filtration, residential landscape water circulation filtration, etc.);

·Intermediate water reuse (river water purification/rainwater reuse/sewage treatment and reuse projects, etc.);

The working principle of cloth filter:

1. Filtration system;

2. Anti-suction + sludge discharge system: The vertical fiber filter cloth system includes special fiber filter cloth, filter cloth support and water collection pipe. The anti-suction device adopts the linear mobile suction of the truss car, and the section after the suction can quickly enter the normal filtering state without storing the suction water. The working process is as follows:

Anti-suction/sludge drainage——As the raw water filtration continues, the suspended matter on the surface of the filter cloth continues to accumulate, and the resistance of the filter cloth filter tank for water circulation continues to increase. The water level in the filter tank begins to rise, triggering the level switch to Start the anti-suction device and start the negative pressure suction; the vertical filter plate is fixed; the truss starts to move linearly, and the mud suction pump is turned on to start the linear scanning suction of the flocs loaded on the surface of the filter cloth; The sucked mud water is discharged from the mud suction pump to the mud drain; the cleaned filter cloth immediately enters the filtering state.

Filtration——The raw water enters the filter cloth filter tank through the water inlet pipe, and evenly spreads the entire pool body. The raw water is tightly filtered from both sides of the filter cloth to the inside of the filter cloth, and the suspended solids in the raw water are hung on the outside of the filter cloth. , The filtered water is discharged through the outlet at the bottom of the pool body, and the normal filtering is completed.
