| Popis: | There has been analyzed the nature of the distribution of the oxidability of water. It is revealed that the nature of the distribution of indicator values during the year depends largely on the seasonal factor, and therefore the analysis of the distribution of oxidability is proposed to be studied separately for each month. A variation series is constructed and empirical distribution functions of oxidability distribution is derived. It is established that the law of water oxidability distribution differs from the normal and lognormal distributions, but it is described with sufficient accuracy by the gamma distribution or by a cubic polynomial function (being the simplest). The hypothesis about the distribution law is confirmed by the Kolmogorov–Smirnov test. The water oxidability distribution function allows to determine the probability of exceeding the specified values of the indicator and quantitatively assess the risks of exceeding them, which can become the basis for developing solutions for managing water quality and increasing the efficiency of the water treatment process. |
