Abstract

Purpose. To determine and evaluate technogenic risks within the water purifi cation systems of TSs and TPSs during normal operation in terms of electrocoagulation plant. Methodology. It is proposed to apply a fault tree method for the analysis of various operation failures of water purifi cation facilities in the heat power industry. Additional analysis method, applied at stages one and two of technogenic risk determination, is suggested for its use. The method is based upon the construction of matrix combining states of the system elements. Findings. The aggregation of the combination matrix and fault tree method makes it possible to derive a new grapho-analytical procedure to analyse probabilities of technogenic risk initiation in the context of any water purifi cation system operation both at the stage of its design and at the stage of its work. Originality. Non-routine operation of a water purifi cation system may depend upon certain internal reasons as well the external ones. The reasons pose risks to a situation that at the output of the system, water will turn out being insuffi ciently purifi ed. It has been identifi ed that in terms of the non-routine operation of water purifi cation system, risk probability is worth analysing with the help of the fault tree serving as graphical representation of causal relationships obtained while considering dangerous situations in reverse order to determine probabilities for their initiation. Practical value. The procedure helps obtain quantitative, qualitative, and causal-consequential indicators facilitating control of technogenic risk initiation in water purifi cation systems. Software has been developed to calculate rapidly the probabilities of running of block elements or water purifi cation system elements in an ‘operation’ mode or in a ‘failure’ mode, and see clearly the ‘poorest’ combinations in terms of an electrocoagulation water purifi cation system.
