REVERSE OSMOSIS DESALINATORS
FOR PRODUCTION OF STERILE FRESH DRINKING WATER
FROM BRACKISH WATER AND SEA WATER

	Reverse Osmosis is a process which allows to remove salts and organic material from brackish and sea water, by means of a syntetic semipermeable membrane. In order to resalize the process, it is necessary to put under high pressure the water to be treated. Under the effect of pressure a portion of water passes through the membrane and this is pure H2O and small percentage of salts, as required for the water to be drinkable. The remaining part is a more concentrated water, which must be discarded. The water produced is drinkable, of very good quality and even sterile. Infact, if the membrane rejects the salt molecules it rejects also bacteria and viruses which are formed by milions of molecules everyone.
The high pressure pump is the only part in movement and the electric energy required for one liter of sweet water produced is so low to render this process much more economic and convenient than resin deionization or vaporation. Membranes have normally a life over 5 years. The maintenance required is negligibile. The quality of the water produced is excellent and comparable to the one of the best natural spring. Our machines are constructed with a modular system using one or more membrane elements moreover described. The membranes are lodged inside suitable pressure vessels. All our system are complete of an high pressure pump. Pressure is regulated by means of a regulating valve. Vessels and tubes are supported by a mild painted steel frame which also supports the pump, the electric control panel and the instrumentation. In our desalinator are placed one or more membranes made in new amidic copolymer resistant up to 45°C, 0.2 ppm free chlorine, pH from 2 to 12, high permeability per m2. The membranes are lodged inside suitable pressure vessels and are of the spiral of 300-400 mg/l like the best light mineral waters. The membrane porosity is only 0,0004 microns. The produced water is free from viruses, bacteria, organic pollutants being those ones much larger than the membrane pores.
For brackish water: DOMOPURE Models very simple and low priced, with capacity from 30 l/h (720 l/day) up to 590 l/h (14.200 l/day). Suitable for producing the whole daily need of a family, a bar hotel kitchen or a small residence. Membrane with 98% salt rejection. SEPRO Models with capacity ranging from 85.5 l/h (20.5 m.cubi/day) up to 11.8 l/h (342 m.cubi/day). Constructed with industrial type components. Plants skid mounted and complete of normal prepost-treatment. Fully automatic functioning. Membrane with 98% salt rejection.		For sea water: ECOPURE Models highly professional complete with many instruments and automation. Nominal capacity from 30 l/h (720 l/day) up to 590 l/h (14.160) l/day). Membrane with salt rejection over 99%. High pressure pump in marine bronze and components in the high pressure line enirely in stainless steel AISI 316 for an intensive use of our machine or for exigent customers who want to buy the best. AMRO Models with nominal capacity from 712 l/h (17 tons/day) up to 11.400 l/h (274 tons/day), manufactured with the same criteria of the models SEPRO, but complete with membranes for sea water with salt rejection over 99%.
