Wastewater contaminated with hexamethylenediamine (HMD), which is discharged into natural reservoirs, causes damage and loss of hydrobionts, worsens the quality of water which becomes unsuitable for use. For wastewater treatment from HMD, the possibility of applying bacterial cultures-destructors which use the HMD as a nutrition source is considered.

HMD is widely used by industry in the manufacture of polyamide materials, as well as a substance in the production of epoxy resins and other substances. At the same time, HMD is a physiologically active, toxic and dangerous substance (hazard class II), which can cause burns, eczema-like dermatitis, diseases of the nervous system and gastrointestinal tract in humans. Wastewater contaminated with HMD, which is discharged into natural reservoirs, causes the death of aquatic organisms and aquatic vegetation, degrades the quality of water, which becomes unusable. HMDA is listed as a hazardous substance by the European Chemicals Agency and the American Conference of Government Hygienists of Industry.

The purpose of this work is the study of fortified food products. The prerequisites and consequences of protein deficiency, the impact of an insufficient amount of food protein in the diet on human health are studied. The ways of solving the problem of protein deficiency in Ukraine have been studied. The article substantiates the expediency of using concentrates, co-precipitates and isolates, in particular from non-fish products of the sea in the technologies of food products with an increased content of protein substances.

Purpose. Concept of deviation as a quality estimation of complex ecological informational systems efficiency and their robustness ability is proposed. Deviations, their alternatives and their validity may be evaluated by means of heuristics, which operate mainly by fuzzy data and membership functions. Methodology. The deviations’ evaluation methods of system, algorithm of its optimization and proper heuristics are submitted. The search of acceptable deviations in bounds of which the CCAS is capable for effective operating is extraordinarily significant task of up-to-data. As an example of deviation evaluation one can cite an analysis of CCAS behavior under conditions of sources and connectivity’s alterations. Results. The main operation functions of CCAS are considered as admissible and their performability is satisfactory when the system remains in predicted extent or goes over to another legitimated predictive extent. This transition is transfer to alternative deviation – eventual way to implementation of installation-specific activity. Along this way there are the variety of problems due to information fuzziness and incompleteness on base of which it should be decision making relatively to identification of some satisfactory deviations. It is proposed an approach which facilitates to identify and to estimate principally possible alternative deviations i.e. the variety operable virtual CCAS capable by some way to achieve the functions which are entrust on them while their robustness should be guaranteed under conditions of possible structural and behavioral disturbances. Originality. A lot of attention in the world is paid to sustainable development concepts now. This concept implies the combination of natural and man-made cycles into a single system for the purpose of managing these cycles at the expense of «buffer» zones that exist objectively. Practical value. All processes of WW treatment are characterized by fuzzy specifications of parameters and variables which participate in the processes. Іnstead of clear-cut dependencies and models it is admitted to apply the heuristics with membership functions and suitable linguistic variables. References 10, figures 3.
