Requirement 1: the process of reducing the minimum inhibitory concentration (MIC) of an organism for at least one bacterial strain and / or at least one yeast strain and / or at least one fungal strain during the preparation of water, including the following steps: (a) the preparation state of production water, (b) Including at least one biocide, (c) including at least one dissolved lithium ion source, (d) associating the water preparation state of step (a) with at least one biocide of step B,At least one of the biocides is effective against at least one bacterial strain and / or at least one yeast strain and / or at least one fungal strain if the strain is present in a water ready state, (e) Before and / or during and / or after step (a), connect the water preparation state of step (d) with at least one dissolved lithium ion source in step (c), and its content shall reach at least one biological inhibition concentration (MIC), that is, at least one bacterial strain and / or at least one bacterial strain Yeast and / or yeastr at least one strain of mold satisfies equation (1): MICₛⁱₙLⁱ / MICLⁱ ³ 1.1 (1) where MICₛⁱₙLⁱ is the minimum inhibitory concentration (MIC) of said at least one biocide against said at least one bacterial strain and / or at least one strain of yeast and / or at least one strain of mold without said at least one water-soluble source of lithium ion in ppmCalculate the water weight in the water preparation process according to step A,Micl83055 is the minimum inhibitory concentration (MIC) of at least one bacterial strain and / or at least one yeast strain and / or at least one fungal strain containing at least one ppm lithium ion soluble solution source, calculated by the weight of water in water preparation. Step-by-stepAt least one soluble lithium ion source exists in the water phase of water preparation, and its proportion makes the total lithium ion between 15.0 and 800.0 mmol / L, calculated according to the weight of water in water preparati
