摘要： A method for purifying a nonaqueous liquid substance includes: filling a cartridge container with a macroporous or porous type ion exchange resin in a water-wet state to obtain an ion exchange resin-filled cartridge filled with the macroporous or porous type ion exchange resin before water content reduction; reducing a water content of the macroporous or porous type ion exchange resin in the cartridge container until a water content (A) of the macroporous or porous type ion exchange resin after water content reduction becomes 90 to 97% of a water content (B) of the macroporous or porous type ion exchange resin in a saturated equilibrium state; an initial blowing step of allowing the nonaqueous liquid substance before being purified to pass inside the cartridge container filled with the macroporous or porous type ion exchange resin after water content reduction and discharging an initial blow effluent from inside the cartridge container; and purification.

摘要： Provided is a production apparatus of a non-aqueous electrolyte solution that can produce conveniently and at a low cost the non-aqueous electrolyte solution while readily controlling an acidic impurity concentration so as to be in a prescribed level.
The production apparatus of the non-aqueous electrolyte solution includes an original liquid tank that stores a liquid to be processed containing a non-aqueous electrolyte solution, and an ion-exchange resin container that accommodates a weakly basic anion-exchange resin, and also including a liquid circulation pipe that returns the liquid to be processed that is obtained after flowing the liquid to be processed from the original liquid tank through the ion-exchange resin container to the original liquid tank.-

摘要： Provided is a sterilization method for a water system, the sterilization method being capable of suppressing the production amount of a nitrosamine compound while exhibiting a sufficient sterilization effect in precursor-containing water that contains a nitrosamine compound precursor. In the sterilization method for a water system, a stabilizing composition containing a bromine-based oxidizing agent or a chlorine-based oxidizing agent and a sulfamic acid compound is added to the precursor-containing water that contains the nitrosamine compound precursor.

摘要： Provided are: a water treatment method that includes at least a denitrification step for denitrifying water to be treated with a denitrifying bacterium in the presence of a hydrogen donor, wherein the denitrification activity of the denitrifying bacterium can be maintained at a high level and thus the treatment speed can be increased; and a water treatment apparatus. The water treatment method includes at least a denitrification step for passing water to be treated through a biological treatment tank and denitrifying the same with a heterotrophic denitrifying bacterium in the presence of a hydrogen donor, wherein: molybdenum is added to the water to be treated to give a concentration of 0.01-1.0 mgMo/gN; a carrier is added to the biological treatment tank; and the nitrogen load to the carrier is controlled to 1.6 kgN/(m3-carrier·d) or greater.

摘要： A diluted solution production method of the present invention is a diluted solution production method of producing a diluted solution of a second liquid by adding the second liquid a first liquid, the method including feeding the first liquid to a first pipe; and controlling pressure in a tank that stores the second liquid to add, through the second pipe that connects the tank to the first pipe, the second liquid to the first liquid in the first pipe. Adding the second liquid includes measuring a flow rate of the first liquid or the diluted solution that flows through the first pipe; measuring a component concentration of the diluted solution; and controlling the pressure in the tank, based on the measured values of the flow rate and the component concentration, so as to adjust the component concentration of the diluted solution to a specified value.
