Automatic sand filter Nobel mod. FCD/F complete of filtering column, with vessel in coated carbon steel, with internal lining made with epoxy coated (thickness 300 µm) applied after sand blasting at the Sa3 of the Swedish scale; the external lining in polyuretanic acid-proof painting applied after sand blasting as above.
The vessel is made complete of man-holes, plate with a proper quantity of filter-nozzels made in polypropylene, for water distribution inside the filter.
The filter is equipped with INLET – OUTLET manifolds, including nos. 5 pneumatically controlled butterfly valves with pneumatic actuator double effect, media filter including three layers of selected quartz-sand, spheroidal type, with different grain-size and a top layer of anthracyte.
Fully automatic control by electronic programmer, according to the following modes :
FCD/FT according to (adjustable) time schedule
FCD/F-DP according to pressure drop and/or time schedule.
Dual models : two filters installed on parallel and both on service in the same time. The regeneration, by time (FT) or by pressure drop (F-DP) is featured on one filter at a time. This arrangement allows to reduce the backwashing flow rate required.
Desalination systems by reverse osmosis. Designed to produce deionized water from drinking water or to produce drinking water from brackish water. Production of treated water up to 30.000 l/h (up to 720.000 l/day)
Automatic filters to remove iron and manganese from water, top of the line. Strong and reliable are designed for industrial applications or even for huge block or flat with butterfly valves for highest reliability.

(38+38 for Dual models)
Automatic activated carbon filters, to remove residual chlorine, organic substances, polluttants; top of the line. Strong and reliable are designed for industrial applications or even for huge block or flat, with butterfly valves for highest reliability. Flow rates up to 114 m³/h (114+114 for Dual models)
