Automatic Backwash Disc Filter: Automatic Cleaning, Worry-Free Irrigation

The automatic backwash disc filter is an efficient water treatment device, with the core component of this system being a filter element composed of multiple grooved discs stacked together to form a cylindrical filter element. Water flows through the narrow channels between the discs, effectively capturing particles and impurities of various sizes.

This filtration system is capable of automatically cleaning the filter element through reverse water flow, thereby removing dirt and debris attached to the discs. This self-cleaning mechanism not only reduces maintenance requirements but also ensures that the filter remains in optimal working condition for extended periods. The automatic backwash disc filter features efficient backwash, fully automatic continuous operation, low self-water consumption, small footprint, and reliable operation. The operation of automatic backwash is simple, greatly reducing the need for manual intervention, making it particularly suitable for industrial applications and irrigation systems that require continuous operation.

T-Type Automatic Backwash Disc Filter

The T-type automatic backwash disc filter is a cost-effective filtration device with a modular design, primarily composed of multiple T-type disc filters, valves, control panels, manifolds, and a metal frame. It can be easily adjusted or expanded according to specific filtration needs and site conditions, making it suitable for treating water sources with a high content of organic and inorganic impurities.

Moreover, the system's efficient backwash performance means that a significant amount of water and energy can be saved during the filtration process, while also reducing operational interruptions caused by frequent cleaning or replacement of filter elements.

Features
  • High safety performance. The materials and design used in the product ensure durability and a long service life.
  • High working efficiency. It adopts a centrifugal system more water-saving and energy-efficient, minimizing maintenance frequency and intensity.
  • Automatic backwash filter element. It minimizes water consumption, efficiently cleans large filtration areas, with filter rating ranging from 5 to 500 microns, and a low backwash pressure.
  • Easy to transport and install. The filtration system is fully assembled, no tools is required.
  • Low maintenance cost. The material is corrosion-resistant and wear-resistant and can not be damaged easily.
Working Principle
Filtration Stage

Water enters the filter and flows at high speed through the spiral disc at the bottom of the disc set, creating a centrifugal effect that causes impurity particles in the water to move away from the discs, and then in-depth filtration is performed through the discs.

Backwash Stage

Filtered water enters the filter in the reverse direction, passing through the filter element, the discs loosen, and backwash operation is performed. Impurity particles are washed off from the small grooves of the discs and discharged through the drain pipe. The discs of the filter are compressed again, entering the filtration state.
