The machines of the RO TEC series are designed, sized and built with procedures in strict quality regime and with particular attention to the containment of energy and water consumption.

The reverse osmosis units of the RO TEC family are suitable for continuous operation and professional use in the community, industrial, agricultural and technological fields; they can be used in the standard execution up to pressures of 13 bar (at 15 ° C) using different types of membranes.

The RO TEC are characterized by high ergonomics and easy maintenance accessibility with the peculiarity of having an excellent quality-price ratio.

Their operation is managed with PLC logic and "flushing" is foreseen at the end of the work cycle, at programmable intermediate time and every 24 hours of inactivity in order to avoid premature deterioration of the membranes. Flow rate: from 8000 to about 46000 liters / day (in the standard versions).

Reverse osmosis on membrane

It is a membrane process, which allows almost all of the substan- ces present in it to be removed from the water.

The water in the feed is pressurized by a pump which exerts a pressure higher than the osmotic one, obtaining two flows: the permeate, poor in salts and the concentrate with a high salt concentration, due to the accumulation of all the salts which do not have crossed the membrane.
