An apparatus for dispensing a mixture of a diluent and an additive for sanitation, cosmetic or cleaning applications. The apparatus includes a mixing unit for creating a mixture of the diluent and the additive, a diluent supply supplying the diluent to the mixing unit, an additive supply supplying the additive to the mixing unit, an outlet for dispensing the mixture. The diluent supply includes a pump arranged to increase the pressure of the diluent before the diluent enters the mixing unit.

Provided are methods and systems for delivering a treatment fluid to a wellsite. An example method includes receiving a container containing a treatment fluid component from a treatment fluid component supplier. The method further includes introducing the treatment fluid component into a wellbore from the container by pumping the treatment fluid component out of the container and into the wellbore. The treatment fluid component is not transferred to another container during the receiving or the introducing.

Provided are a method for supplying water of specified concentration, including: a step of adding at least two liquids, a conductive first liquid and a non-conductive second liquid, to ultrapure water to produce water of specified concentration containing a first liquid-component and a second liquid-component at specified concentrations, in which a mixed solution in which the first liquid and the second liquid are mixed at a specified mixing ratio in advance is prepared; and the mixed solution is added to the ultrapure water so that a conductivity or specific resistance of the ultrapure water after the addition satisfies a specified value, and an apparatus therefor.
