Water is transferred to the filter through the upper stub pipe, form where it is equally distributed on the filtration bed. Filtration process is carried out in the same manner as in the traditional pressure filter, where water flows down through the filtration material being mechanically cleaned in the same time.
Filtrate outflow after first treatment stage is carried through the stub pipe located in lower end cap, where preliminarily cleaned water is supplied through an inflow to the second chamber, where it is transported up through the filtration bed.
Treated water is transferred through the duct located in the filtration chamber upper part. Both, filtration and flushing, are automatically regulated. Valves regulation and switching sequences are controlled by the control module provided together with the device.
