Reverse osmosis is the way to desalinate water and get rid of unwanted dissolved elements, because of the fine way of filtering. So fine that it even removes dissolved elements from water. This filtration technique is frequently used in horticulture to upgrade spring water to high-quality watering. This way, one has water with a low EC and little sodium. This is important for optimising the growth of the crop and, in addition, circulation can be extended before irrigation is necessary. Reverse osmosis is also widely used to extend the life of installations. Examples are the filtration of feed water from boilers and high-pressure mist installations. After filtration, no dissolved elements are present that could cause problems, such as limestone formation. That is why it is also used to rinse products such as cars and windows spotlessly.
