OSM
Osmosis Plant
The acronym OSM identifies the product range that adopts the principle of Reverse Osmosis for water demineralization through a physical process that exploits the osmotic pressure difference created between the membrane and the liquid (water), achieving total or partial removal of dissolved salts and minerals.
This is a process that occurs naturally. It is the process by which, between two solutions of different salt concentration, separated by a semipermeable membrane (which allows the passage of water but not salts), the more dilute solution tends to naturally move towards the more concentrated solution until the concentration of the two solutions is the same.
By reversing this process, applying equal and opposite pressure to the concentrated solution, a solution with lower concentration is obtained. In this case, it is called Reverse Osmosis.
In practice, the osmotic membrane acts as a barrier against both dissolved salts and inorganic substances such as pesticides, pyrogens, viruses, and bacteria.
The semipermeable membrane inside the OSM unit cannot remove 100% of the salts. It is therefore necessary to find a balance between feed water (inlet), produced water (permeate), and concentrated discharge water (rejection).
The OSM produces demineralized water, with programmable values, normally used in washing machines to achieve perfect washing without leaving residues on glass surfaces. It is indeed essential to carry out washing with demineralized water in the production processes of Laminated Glass or Insulated Glass to obtain a perfectly clean surface before proceeding to glass coupling.
It is equally demanded, for the sake of the final product quality, even in the most delicate and sensitive processes to any residues on the glass surface, such as screen printing and tempering. The OSMs can serve a single washing machine, or a group of washing machines, or entire industrial plants, being sized for production from 100 liters/hour up to volumes of 20,000 liters/hour and beyond, upon specific design.
The water obtained from the osmotic process will be stored in a tank from which a pump/accumulator system will send it to the connected machines.
All OSM plants can be equipped with pre-treatment and post-treatment systems depending on the type of water to be treated (feed water), the intended use, the type of membrane used, as well as the rejection quantity.
