Reverse osmosis is a modern process based on the use of semi-permeable membranes that have the property of letting water pass, without letting the substances it contains in solution through.
In physics, by introducing pure water into two communicating vessels, separated by a semipermeable membrane, the water reaches the same level in the two vessels. By adding a salt in vessel B, the water is pushed by a natural force (osmotic pressure) to pass from the saline solution (B) to the solution with lower salinity (A); this important phenomenon is called OSMOSIS.
To reverse the phenomenon, it is sufficient that the water with a high salt content is pushed through the membrane by a pump that exerts a higher and opposite pressure to the osmotic one.
This principle, called “reverse osmosis”, makes it possible to obtain two outgoing flows at different concentrations from a starting saline water flow: the “permeate”, pure water, poor in dissolved salts and micro pollutants, suitable for use in various sectors (industrial, hydro-drinking, food, etc.) and the “concentrate, rich in salinity, which is generally destined for waste.
Our osmosis systems are designed and built following strict quality regimes and with particular attention to the containment of energy and water consumption. The plants were created to meet the needs in the civil and industrial sectors, guaranteeing high performance in terms of reliability and quality of the permeate produced. The standard machines are supplied pre-assembled in compact form on steel frames with an exclusive design, to minimise pace and simplify maintenance and inspection activities.
The systems are completely automatic and managed by a PLC with a touch-screen HMI interface for the simple display and adjustment of the running parameters, the quality of the permeate and the signalling of any anomalies. The systems can be controlled remotely (PC or Smartphone) and are designed for communication and integration with other existing systems.
The main applications of reverse osmosis (RO) systems are:
- Food and beverage production
- Pre-treatment for boilers and cooling towers
- Pre-treatment for high purity systems (EDI)
- Biopharmaceutical productions
- Water jet cutting
- Humidification and steam production
- Power generation
