Aytok Hydrofilt VBE/CVBE 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  VBE  series, and the version of stainless steel body CVBE 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.

In sample view of the CVBE filter in Picture-1 is used stainless steel body.

Working Principle

Filter section according to Picture; 1- Dirty water inlet, 2-Clean water outlet, 3- Backwash dirty water outlet drainage, 4-Sieve internal kit (multi-layer), 5-Collector kit (backwash water vacuuming channel ), 6-Turbine chamber, 7-Piston part.
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 returns cleaning collector through hydraulic turbine and drainage pipe after vacuuming the pollution in the inner surface of filter by creating a vacuum effect at nozzles.
Pressure decrease consist in turbine part and piston drainage provides a linear motion to 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 makes a second backwash and returns to its original position, so washing process is completed. During backwash filtering  process continues.

For efficiently work of system, during backwash process inlet pressure must not be less than 2,5 bar .
