Aytok Hydrofilt VBE 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 (9V) 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 VBE 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.

VBE Automatic Filter Parts: 1- Dirty water inlet, 2- Clean water outlet, 3- Discharge (drainage) backwash dirty water outlet with a hydraulic control valve, 4- Screen cartridge set (multi-layer including shield and screen), 5- Collector set (backwash water vacuuming channel), 6- Turbine room, 7- Piston section The water enters to from inlet and passes through the area where the fine screen is located. The water then flows to the outlet, the water forms the pollution layer on the inner surface of the screen, and this pollution causes a pressure difference at the inlet and outlet of the filter. As soon as this pressure difference reaches to a predetermined level, backwashing starts automatically.

Working Principle

The water enters to from inlet and passes through the area where the fine screen is located. The water then flows to the outlet, the water forms the pollution layer on the inner surface of the screen, and this pollution causes a pressure difference at the inlet and outlet of the filter. As soon as this pressure difference reaches to a predetermined level, backwashing starts automatically. At a specified value, the backwash control unit opens the drain valve and creates a strong atmosphere backwash pressure in the drain pipe. The flow occured by this backwash pressure absorbs the dirt on the inner surface of the filter by making a vacuum effect on the nozzles and rotates the cleaning collector by passing through the cleaning collector, hydraulic turbine and 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.
