摘要
The aims of the invention, as well as others that will appear later, are achieved by means of a method for treating water with a view to desalinating same, said process consisting of: a step (I) of coagulating said water; a step (ii) of flocculating said water from said coagulation step (i); a step (iii) of the granular filtration of the water directly from said flocculation step (ii) through at least one granular filter including a filtration medium consisting of at least one layer of at least one filtration material; a step (iv) of filtering the water from said granular filtration step (iii) to a cutoff threshold of between 10 nanometers and 10 micrometers; a step (v) of filtering, by inverse osmosis, the water from said filtration step (iv) to a cutoff threshold of between 10 nanometers and 10 micrometers; and a step (vi) of recovering at least partially desalinated water from said reverse-osmosis filtration step (iv); said granular filtration step (iii) consisting of causing water from said flocculation step (ii) to pass through said granular filter at a speed of between 15 and 25 m/h.
