Aytok Hydrofilt HBE/CHBE filters; are electronically controlled capable of fully automatic backwash filters. For this process, the pumping of water will be enough and no need for extra energy. However, the electronic control unit must be powered by an internal battery in order to detect the contamination and start the backwash. By the help of the pressure occured as a result of the energy that the water receives from the pump, fully automatic backwashing is carried out and all filtering element are automatically cleaned. While this backwashing mechanism is operating, the filtering process continues. The dirty water occured in this process is automatically discharged during backwashing.Considering these aspects, the HBE series and its stainless body version (CHBE) series are fully automatic filters and more agile and efficient than systems with manual backwash and semi-automatic backwash. It also minimizes the user's time and water loss.

Working Principle
The water entering the filter passes through the coarse screen and passes to the area where the fine screen filter is located. The water continues to flow from the fine screen to the outlet and creates a layer of pollution on the inner surface of the fine screen and this pollution causes a pressure difference at the inlet and outlet of the filter. As soon as this pressure difference reaches a predetermined level, backwashing starts and the backwash control unit opens the discharge valve. Atmospheric pressure creates a strong backwash in the discharge pipe and a strong flow ls also provided. This flow creats vacuum effect on the nozzles and the nozzles absorb the dirty layer from the inner surface of the filter. The cleaning collector rotates at this time and dirty water is discharged by passing through the cleaning collector, hydraulic turbine and the drainage pipe. In the turbine chamber, the piston and the piston rod provide a linear motion to the cleaning collector. This rotation and linear movement ensures that the pollution layer on the inner surface of the filter is absorbed by the nozzles. When the process is finished, the cleaning collector returns to its original position automatically and the washing process is completed. During the backwash, the filtering process continues. In order to work the system efficiently, the inlet pressure should not be less than 2 bar (29 psi) during backwashing.
