In significant volumes of hazardous industrial discharges, inefficiencies and long-term measurements, in terms of environmental safety, are unacceptable – especially in the context of the potential impact of emergency situations. At the same time, modern means of automatic water measurement are of low accuracy and speed. They allow set quantitative indicators only, including  the  temperature,  pH,  flow  rate,  pressure,  concentration of  suspended  particles,  turbidity  and  total  salt  content,  and  a number of other parameters. Within the framework of the current research, the model is developed for assessing the risks of the operation  of  the  respective  industrial  and  natural  phenomena. This model  considers  the  energy  efficiency  criterion  of  electro-technological water purification  to  form a quantitative picture of  the potential emergence of emergency situations. The basis of model  is built on  the dependence of  the water quality after processing of  real industrial waste water  from multipurpose objects. Data  that meet  the  requirements  of  adequacy, with  the  further  development  of  technological  dependencies,  is  obtained due  to creating  the  virtual measure  of  electrochemical water  purification.  The  virtual measure  consists  of  physical  and mathematical blocks  of  technological  processes  simulation.  Physical  modeling  includes  electrolysis  (pH  correction,  destruction, electrocoagulation,  electro  flotation),  aeration, hydro-separation, and  sorption  filtration. Mathematical modeling  is based on  the filtration of the input signal, the correction of temperature influence by robust systems and the synthesis of the neural network for the  formation  of  water  quality  dependencies  after  processing  from  the  regime  parameters.  The  software  allows  adapting  the functioning of the virtual measure according to the criterion of energy efficiency. 

The data received in real time allows improve the scientific and technical bases of normative provision of water purification systems, including recommendations for the design of such the systems and further development of technological regulations for multipurpose objects.
