Reverse Osmosis
Water/ Fertilizer systemsThe principle of reverse osmosis
OSMOSIS is the name for the phenomenon where a liquid passes through a semi-permeable wall (membrane). This membrane allows the liquid as such to pass through, but not the substances that are dissolved in it, if solutions containing salts in different concentrations are present on the two sides of the membrane. The equilibrium between the two solutions is expressed as the difference between the levels: it is also referred to as osmotic pressure.
REVERSE OSMOSIS is the name for the phenomenon, where a liquid is caused to pass through a semi-permeable membrane under the action of mechanical pressure to the liquid that is greater than the osmotic pressure, when the dissolved compounds are left behind.
The HORTI PURE RO series reverse osmosis installations are in most cases connected directly to the well water and work in accordance with the so-called crossflow circulation principle. During this crossflow circulation, the feed water is passed at high pressure and great speed over the membrane. Part of the water passes through the membrane (permeate/pure water); the remaining water (concentrate/reject) is taken in part to the drainage system or if possible to a negative well. The permeate produced is chemically, physically and bacteriologically clean water.
