The invention relates to a method and a system for purifying water whereby: the water to be purified is pressurized; a pressurized flow of said water is directed onto at least one selective permeability membrane to divide () the flow of pressurized water into a permeate flow and a retentate flow; the permeate flow is electrodeionized () to produce a flow of purified water consisting of the electrodeionized permeate flow; the flowrate of the retentate flow () is reduced; a substantially constant predetermined pressure () is maintained on the selective permeability membrane(s); and a substantially constant predetermined permeate flowrate is maintained and also relates to a suitable tangential filtration module system.
