Automatic softeners
for middle-high flow rates
Automatic softener Nobel mod. AM/V Duplex, complete with nos 2 vessels made in coated carbon steel vessel, complete of man-holes, plate with a proper quantity of filter-nozzels made in polypropylene, for water distribution inside the filter.
The internal lining is made with epoxy coated applied after sand blasting at the Sa3 of the Swedish scale; the external one in polyuretanic acid-proof painting applied after sand blasting as above.
Each vessel is equipped with multiport compact control valve, side mounted and nos. 2 hydro-pneumatically controlled membrane valves, to divert the flows during the several cycle of regeneration The valves manifolds are made with galvanized steel, external coated as above. The control valves are made in ABS Bayer, while membrane valves are made in cast-iron, with membrane in EPDM. The brine tank is made in polyethilene, complete with separation plate, float valves, protection pipe.
The media filter includes a layer of food grade ion exchange resins, strong cation type, NaCl regenerated, supported by a layer of selected quartz-sand spheroidal type
The described softener is automatic, dual system, alternating working (1 column always in service, one column on regeneration or stand-by), via volume control.
It allows to supply treated water 24 hours a day no-stop.
The start of the regeneration of the exhausted column and the exchange of working between the columns works automatically, according to the pre-set volume of treated water.
The automatic facility includes an electronic programmer with pulse-counter that handles the working of the control valves and membrane valves, according to the pulses received by a water meter. An adjustable drain valve is mounted on drain line, in order to adjust the backwash flow rate.
The cation resins will be automatically regenerated according to volume schedule.
After the regeneration, fully automatically controlled, the systems turns this vessel in stand-by position..
The drawing of brine for regeneration will be made by injectors, automatically from the brine tank.
