A method of producing treated ion exchange resin material includes exposing an enclosed vessel containing ion exchange resin and a pre-treatment solution to high energy radiation. The treated ion exchange resin material has reduced organic impurities or total organic carbon (TOC).

A laboratory water generation and distribution system capable of distributing laboratory water at different temperatures is disclosed. A laboratory water generation section is configured to receive potable water and treat the potable water to generate laboratory water. A laboratory water distribution section comprises a laboratory water storage tank and a main distribution loop fluidly communicating with the laboratory water storage tank to receive the laboratory water therefrom. The laboratory water distribution section further comprises a sub distribution loop operatively connected to the main distribution loop via a valve to receive the laboratory water therefrom. The sub distribution loop returns to the main distribution loop and dispenses the laboratory water to the main distribution loop.

A first stream of an aqueous solution flows through an upstream desalination or nanofiltration system. A second stream of the aqueous solution is mixed with the diluate output from the upstream desalination system or with the diluate or concentrate output from the upstream nanofiltration system with a flow ratio of the second stream of the aqueous solution to the feed stream of <0.47 or >0.63. A liquid composition flows into the concentrate channels of an electrically driven separation apparatus, while the feed stream flows into at least the diluate channels at a ratio of 0.3 to 0.81 to the flow of the liquid composition. An applied voltage selectively draws monovalent ions from the feed stream in the diluate channels through the monovalent-selective ion exchange membranes into the concentrate channels to produce a treated diluate having a sodium chloride ratio (SCR)<0.7.

The present invention relates to a method for producing purified water comprising a step (a) of passing water through a first mixed bed ion exchanger comprising beads having a diameter between 0.5 and 0.7 mm and a step (b) of passing water through a second mixed bed ion exchanger comprising beads having a diameter of less than 0.5 mm. The invention further relates to a module comprising the first and second mixed bed ion exchanger and to a water treatment system for producing ultrapure water comprising the first and second mixed bed ion exchanger.

An ion exchanger includes a housing and a cartridge. The housing has an inlet port, through which coolant flows in, and an outlet port, through which the coolant flows out. The cartridge is detachably attached to the housing. The cartridge is filled with ion-exchange resin. The ion exchanger is configured to remove ions from the coolant through ion exchange when the coolant flowing in the housing passes through the ion-exchange resin. The cartridge includes a bypass route that causes some of the coolant that has flowed into the housing to bypass the ion-exchange resin and flow to the outlet port.
