Vertical Self-Clean Filter - VBEL

Aytok Hydrofilt VBEL/CVBEL filters; are electronically controlled capable of fully automatic backwash filters. For this process, instead of extra energy the pumping of water will be enough. However, detection of pollution and for the initiation of back-washing, the panel must be fed wit a suitable electric installation. By the help of pressure which is occured after the speed that water gets from the pomp, filter cleans itself. So it is provided the self-cleaning of the filter. Filtration process continues while this backwash mechanism is working. Dirty water which occures in this process automatically discharged during backwash. Considering these aspects VBEL series, and the version of stainless steel body CVBEL serie fully automatic filters, are more agile and efficient according to manually backwash and semi-automatic backwash systems. In addition, minimizes user time and loss of water.

Working Principle

Water enters the filter and passes through the part where multi-layer filter, after passes coarse sieve. Water continues to flow from fine filter to exit, creates a layer of pollution inner surface of the filter and this pollution creates pressure difference at inlet and outlet of the filter. Backwash begins when this pressure difference comes at a predetermined level. A specified pressure difference is reached, the backwash control unit opens discharge valve. Atmospheric pressure in discharge pipe creates a strong backwash. This flow drains cleaning collector through cleaning collector, hydraulic turbine and drainage pipe after vacuuming the pollution in the inner surface of filter by creating a vacuum effect at nozzles.

Pressure decrease which occures at hydraulic turbine and drainage of the piston, provides a linear motion to the cleaning collector.
This rotation and linear motion provides absorption of pollution layer in the inner surface of filter by nozzles. When process is completed, cleaning collector automatically and returns to its original position, so washing process is completed. During backwash filtering  process continues.

For efficiently works of system, during backwash process inlet pressure must not be less than 2 bar (29psi).
