Abstract (en)
[origin: WO2020249668A1] Method for making surface water drinkable, which method is aimed at reducing the suspended matter content, turbidity, organic matter content and colour of the water, and is characterised in that it comprises: • a step of nanofiltering the water (2) through at least one nanofiltration membrane (2) which has a breakdown capacity between 800 Da and 2000 Da, preferably between 800 and 1000 Da, the nanofiltration step leading to the acquisition of a permeate (7) and a concentrate (5), • wherein the nanofiltration step is carried out with a conversion rate greater than 95%, • the method being carried out without any step of adding an anti-scaling agent or any step of remineralising the permeate.
