Abstract: The process of controlling a quality of water or aqueous solution introduction in a liquid circuit by circulation, comprises defining liquid sampling sites on the liquid circuit for controlling physicochemical and/or microbiological characteristics, threshold values of the characteristics and control frequencies of the characteristics, storing the characteristics associated with sampling sites and the threshold value associated with the characteristics in a memory of a computer device, and defining a series of scheduled time of liquid sample from the control frequency. The process of controlling a quality of water or aqueous solution introduction in a liquid circuit by circulation, comprises defining liquid sampling sites on the liquid circuit for controlling physicochemical and/or microbiological characteristics, threshold values of the physicochemical and/or microbiological characteristics and control frequencies of the physicochemical and/or microbiological characteristics, storing the physicochemical and/or microbiological characteristics associated with sampling sites and the threshold value associated with the physicochemical and/or microbiological characteristics in a memory of a computer device, defining a series of scheduled time of liquid sample from the control frequency, storing a measured value of the physicochemical and/or microbiological characteristics resulting from analysis of the liquid sample at each scheduled time in the memory of the computer device, comparing the measured value of the physicochemical and/or microbiological characteristics with the threshold value, storing the compared values of physicochemical and/or microbiological characteristics and threshold in the memory of the computer device, transmitting the measured value of the physicochemical and/or microbiological characteristics to identified entity and the comparison of determined value to the threshold value, sending a message from the measured value of the physicochemical and/or microbiological characteristics and the comparison value of the determined value with the threshold value to the identified entity after analyzing sample of the liquid, forming a loop having a liquid distribution valve using a liquid distribution circuit, and connecting the liquid distribution circuit having a water treatment installation to a liquid power supply. The transmitting step comprises establishing a selective access to the memory of the computer device in which the determined value of the physicochemical and/or microbiological characteristics and the comparison of the determined value with the threshold value are stored. A warning message is send to the identified entity when the measured value of the physicochemical and/or microbiological characteristics is greater than threshold values defined for the physicochemical and/or microbiological characteristics. The threshold value for each physicochemical and/or microbiological characteristic is lower than a predetermined limit value. The first threshold value corresponds to a warning threshold and the second threshold value corresponds to an action threshold. The first control frequency is used when the measured value of the physicochemical and/or microbiological characteristic is lower than the threshold value, and the second control frequency is used when the measured value of the physicochemical and/or microbiological characteristic is higher than the threshold value. A sample of the physicochemical and/or microbiological characteristic is subjected to a computer data processing for its presentation on a graph in a form of a stick, which associates with a marker corresponding to the threshold value and a visual coding to show the determined value of the physicochemical and/or microbiological characteristic is lower or higher than the threshold value. The values of the physicochemical and/or microbiological characteristic are measured respectively on the series of scheduled time stored in the memory of the computer device. The respective values of the physicochemical and/or microbiological characteristics measured from the liquid sample simultaneously on the sampling sites is subjected to the computer data processing for its presentation on a graph to show a spatial variation of the physicochemical and/or microbiological characteristics in the liquid circuit. The sampling sites comprise a first site located in an upstream of the water treatment installation, a second site located in a downstream of the water treatment installation, a third site located at beginning of the loop of liquid distribution circuit and a fourth site located at back of the loop of liquid distribution circuit. The sample of liquid is taken at each scheduled time, and is analyzed for determining the value of physicochemical and/or microbiological characteristics. Independent claims are included for: (1) a device for controlling a quality of water or aqueous solution introduction in a liquid circuit by circulation; and (2) a software.
