Process of Reverse Osmosis

The RO technique is based on a natural phenomenon: the Reverse Osmosis water treatment process. With the use of mechanical pressure, the natural process is reversed (Reverse Osmosis). By applying force, the pure water starts flowing through a membrane. The solutes are left behind in the thickened water (concentrate), on the other side of the membrane. Depending on the type of the membrane; salts, organic compounds, and particulates, amongst other matter, can be left behind in the concentrate.

Through the application of Reverse Osmosis, bacteria (including the Legionella bacteria), as well as viruses, can be prevented. The pure Osmosis water can be used for numerous applications, for example, as irrigation water in the horticultural industry, as supply water for boiler and cooling systems, or as process water in the industrial sector.

Pre-treating Osmosis water: Reverse Osmosis water treatment

The thickened water which remains in the process (concentrate) is wastewater. In order to reduce the loss of water as much as possible, the feed water is pre-treated in some cases. For example, by softening the water, deposits are prevented in the membranes, therefore, pure Osmosis water with a highest possible efficiency is produced and the amount of wasted water is reduced to a minimum.
