The membrane filtrating process, which is applied to water (seawater, well water with high conductivity etc.) where classic treatment systems are insufficient, separates all undesired minerals from water and is oriented to gain pure water, is called REVERSE OSMOSIS. The working principle of the reverse osmosis system is due to membranes placed on the equipment.

Water is forced to circulate under high pressure through porosities on membranes. While water molecules and some inorganic molecules can pass through these porosities during this process most substances in water cannot pass through these porosities and it is exhausted as concentrated water.
What the membrane surface keeps always clear and unblocked is the “cross flow” action realizing within membrane element. While a part of liquid (product water) passes through membrane due to the cross flow another part of liquid (condensed water) hiders bonding impurities to membrane.
