Abstract: A method of purifying tap water to produce deionized type 2 pure water on a laboratory scale with a volume of up to 300 l/h using a water purification system, the method including detecting the permeate flow rate produced by a reverse-osmosis device downstream of a permeate outlet; detecting the flow rate of retentate flow that is removed from the system downstream of a first flow rate regulator; and remote controlling the first and a second flow rate regulators based on the detection results from first and second flow meters such that a predetermined target recovery rate and a predetermined target permeate flow rate are controlled.

Abstract: The invention provides a water purification and dispensing system, preferably for producing ultrapure water and offering the purified water at one or more dispensing sites in a desired volume.

Abstract: A laboratory scale water purification system for producing up to 300 l/h deionized type 2 pure water from tap water, said system comprising a feed medium flow path including a pump (1) for supplying the feed medium under pressure to a feed inlet of a reverse-osmosis (RO) device (2) which is adapted to produce a permeate flow and a concentrate flow from the feed medium. An electro-deionization (EDI) device (10) is provided and has an inlet which is in fluid communication with a permeate outlet of the RO device (2) and has a purified water outlet.

Abstract: A verification and control method for at least one water purification system is described, which includes a step of supplying, by a server embedded with the water purification system, an editing interface comprising a zone for selecting items of exploitation information representing physical quantities associated with the water purification system, a step of selecting, via the first remote browser, at least one item of exploitation information to constitute at least one exploitation interface page, a step of sending a request to access the exploitation page, by a second remote browser, to the server, a step of collecting the value of each physical quantity represented by a selected item of information to constitute the page, and a step of supplying, by the server, the page comprising each collected value.
