reverse osmosis pretreatment

Reverse osmosis has been in use for more than 50 years to remove impurities from water by retaining solvent molecules on a semi-permeable membrane. We bring reverse osmosis membrane technology to perfection in seawater desalination and other applications.

Molecular-size particles
Reverse osmosis filtration is one of only a few available methods to remove particles of molecular size, such as ions and bacteria. To achieve the separation, an external pressure is applied to the contaminated solution that is higher than its osmotic pressure, reversing the natural process of osmosis that wants to create a concentration equilibrium.

The success of reverse osmosis membrane technology started with large research efforts about 50 years ago.

Today this technology is used in nearly every application to purify water. Common users for RO membranes are in industrial wastewater decontamination and in the preparation of drinking water from almost any source. Because of the various nature of water contaminants, different types of RO membranes are available. 

Most are made of polymers like cellulose acetate or are based on TFC polyarmtic compounds, in order to achieve the high structural and chemical stability that have made RO membranes the preferred choice around the world.
The RO membrane is a versatile tool. The size of RO filtration systems varies with its  applications, ranging from bottle-sized personal systems for water purification to the large-scale plants for desalination or industrial water treatment that X-Flow helps to build anywhere.
