The problem of environmental pollution in the process of raw corn starch manufacturing
Nizova E.S., Sereda S.N.
The paper aims at working out a number of practical recommendations for possible improvements in the raw corn starch shop wastewater system of “Novlyansky” public company. The statement of need for the effective environmental management is based on poor quality assessment of wastewater collected in the course of environmental studies and economical production inexpediency according to the open cycle technological schedule. The paper suggests using technical equipment intended to close the technological cycle for the processed water (gluten suspension) and to seek for non-wastewater corn grain processing, thereby reducing the negative impact of hazardous and harmful factors on the environmental security level. A flotation machine designed to extract suspended protein substances out of gluten suspension is to serve as the basic component of the equipment. The pressure flotation technology under study will require no chemical agents. It is a non-waste process as the extracted foam layer is gluten which is a high protein vegetable stock used as a valuable component of feed corn.
Keywords: a loop system, gluten suspension, pressure flotation.

Analysis of efficiency of the ecological risk reduction methods
Sereda S.N.
The aim of work is the system analysis of the efficiency of strategies to provide the required level of the system safety and the reduction of the ecological risk. Environmental and economic feasibility of the proposed solutions, which increase the level of the system safety, are based on the estimation such factors as a probability of accidents, a reliability, a value of damage, the cost of the environmental protection measures and the life safety of workers. The criteria of evaluation of the effectiveness, which take into account both an environmental and an economic indicators, is introduced. The results of the analysis of the typical solutions, which are widely used in practice, are given, such as, the reservation of the system elements, the implementation of the control and protection systems from hazards, the automation of the control processes, the organizational measures on the improvement of the working conditions.
Keywords: model of accident, probability of accident, environmental risk.

Sereda S.N. Estimation of the ecological risk with fuzzy models
Estimation of the ecological risk with fuzzy models
Sereda S.N.
This work is devoted to the system analysis of the possibility of the application of the fuzzy set and models for the estimation of the ecological risk and the system safety. Probabilistic safety analysis is widely used in system analysis for solution of practical tasks of assessment and protection of various processes and systems. In this case it uses a model of a tree incident, showing the causal relationships between the leading event (accident, catastrophe) and their basic assumptions of its occurrence. Often when predicting the safety of the newly designed objects, the values of the probabilities of the prerequisites are not known precisely due to the lack of theoretical models to assess a priori probabilities or the lack of statistic data. In addition, they can be represented interval values, or linguistic (verbal) qualitative characteristics of the background-the causes of the accidents. Therefore, the fuzzy model for evaluation of safety and environmental risk are often used. The interval description indicator of fuzzy values is both a criterion of reliability of the safety assessment. Since an increase in the interval leads to increased uncertainty probabilities, and thus to reduce the degree of reliability of the assessment. Purpose of the work is definition of the character of changes of the criterion of reliability of the changing parameters of the fuzzy set values in the model tree incident. Also the results of the analysis confirm the possibility of application of fuzzy models for the analysis of safety processes and systems at an acceptable level of confidence are given.
Keywords: the model of the system, the evidence tree, the probability of the event, fuzzy set.
