Aytok - Model VDF -Automatic Filters

Water, entered from input collector, passes top art where the multistorey screen fitler in, inside the water (3). It is protected with a rough material with sieve over of multiplex Screen. The thin filter goes to output collector side (2). Particies collected on multiplex screen, constitute a pollution layer over of the fitler and open a back fushing unit washing decharge valve in the output colllector (8) and a powerful back flushing flow consists from decharge pipet o atmosphere (10). This flow cleans the particle layyer, collected on fitler by creating a vacuum from holes over of nozzle (5).

The dirty water, absorbed on multiplex filter, creates a volution by passing from water cleaning nozzle pipe (6) and hydraulic turbine (7). The pressure loss, consisted of turbine container (4) and plunger dreinage (9) constitutes an axial movement. The spiral headway, constituted by this axial and volution together, obtains the absorbing whole filter surface by vacuum nozzles.

When this process is done, the cleaning collector makes a second back flushing and turns its first position. Transaction is completed.

During the back washing, the filtration process contiunes and after the back washing process, the filter stands by until next pressure difference signal.
