Autonomous desalination units
Developed by Mascara NT, a French company based in Chartres, Osmosun desalination plants operate solely on solar energy, without the use of storage batteries. Thanks to their patented technology, these units can smooth the production of fresh water during the day and limit the variations of flow and pressure in the membrane and other water hammer, using a hydraulic energy accumulator, to ensure quality and preservation of the material.
Osmosun watermakers also incorporate an energy recovery system that limits consumption to 2.5 to 3 kWh/m3.
For customers who wish to do so, desalination plants can also be connected to the grid and operate in hybrid with solar energy.
In order to preserve the environment, Osmosun adapts the water withdrawal rate to limit the discharge of salt concentrate into the sea. This can vary from 15 to 35%, i.e. 15 liters of fresh water for every 100 liters drawn. The slow diffusion, linked to the Osmosun production cycle, allows a better reintegration into the natural environment without disturbing the surrounding fauna and flora.
Multiple nautical applications
G & G Boatwash has taken over the distribution of Osmosun for France at the end of 2022 in order to develop the brand in the nautical and harbor uses, in parallel with its boat washing stations. Its associates see multiple applications, as Gaël Minier, president of G & G Boatwash, explains: "The idea is to offer it to marinas, shipyards, or operators of large rental fleets that may be at anchor. This makes it possible to produce fresh water without the need for battery parks or a connection to the grid, we can envisage different applications: supplying pontoons to supply boats with water, supplying pontoons for washing and rinsing the decks of boats afloat and the pontoons themselves, making drinking water available to harbor users, supplying sanitary facilities, mechanics and careening areas, watering."
At a time of water restrictions, the technology has something to inspire operators.
