The invention concerns a treated water purification system () comprising a closed water flow loop () said loop comprising at least one treated water supply point (A), at least one point of use (U) of purified water, a pump means (), a sterilization means () and a filtration means (), characterized in that the zone () comprises the supply point (A) and a water extraction point (P), situated upstream of the supply point (A), and in that the extraction point (P) and the supply point (A) are both situated in a sector (B) of the sterilization zone () that is isolated from the two connection points (R, R) of the loop () to the zone () by two other sectors (A,C) of the zone (). Method for use of such a system.

System and method for purification and distribution of water with separation barrier taking away the biological contamination

The invention concerns a treated water purification system () comprising a water flow loop (), said loop () being closed onto a tank () of treated water to purify, and said loop () successively comprising, in the direction of flow of the water downstream of the tank (), at least one pump means (), at least one first filtration means (), at least one second filtration means () and at least one point of use (U), the system () being characterized in that it further comprises at least one diversionary pipe () linking the first filtration means () to the tank (), and a loop return pipe () linking the second filtration means () to the tank (). Method for use of such a system.

System and method for water purification with automatic purge

A biocidal fluid purification cap () for a fluid container (), preferably one storing purified water for use in laboratory environments and especially purified water for cell culture and water for molecular biology. The purification cap () includes a cap body () including an engagement feature () for removably attaching the cap body () to a mating engagement feature on a spout of the fluid container () to hermetically close a spout opening, at least one LED () adapted to emit light in the UV-C range, electronic circuitry () for driving the LED(s) (), and a power supply for the electronic circuitry (). The LED(s) () is/are arranged in said cap body () so as to be separated from the environment by an UV-transparent window () provided in the cap body () such that light emitted from said LED(s) () enters the opening of the spout when the cap () is attached to the spout of the container ().
