In recent years the mathematical modeling on the basis of constructive descriptive geometry was aimed at work activities, the factors, parameters and components of which can be represented in the form of manydimensional manifolds [1, 2, 3]. Such problems arising in practice in the processes of chemical changes, physical phenomena, socioeconomic events, etc., are impossible to be solved by classic methods of mathematical simulation, as the number of variables reflecting the corresponding multidimensional functional relationships exceeds the dimensionality of the real spatial area, wherein these processes take course. Together with that, the descriptive geometry is able to consider the manydimensional manifolds as function spaces of many variables; that allows it to present such processes visually in the form of surface equations and their geometrical models, from which it is possible to forecast quickly optimum performances and parameters of the studied processes with the help of computer equipment.
The work activities, in terms of constructive geometry, are subdivided into the processes with the chemical substances nonreacting (first method) and reacting with each other (second method). Two methods of obtaining their models in the form of equations and graphic presentation have been developed for their simulation.
Mathematical modeling on the basis of constructive geometry is heuristic, as it is based on the ability to find out functional relationships by manydimensional test values.
The laboratory research allowing obtaining multidimensional arrays of points by experimental methods and simulating real electrochemical and bioparametrical processes on their basis are included into the special course.
The special course includes:
 Brief mathematical introduction.
 Introductory mathematical practical course.
 Introductory laboratory course.
 Laboratory research.
 Research assignments on process optimization.
Brief mathematical introduction.
The values, which are the factors, parameters and components, can appear as variables at the mathematical modeling.
In the chemical systems, wherein the substances do not react with each other, the number of components is equal to the number of constituents (first method). In the chemical systems, wherein the substances undergo reactions, the number of components changes in the process of reaction.
To apply the first modeling method the theorem is proved:
The sum of equations of right sections of a connective gives an equation of the surface bearing these sections [4].
The second method allows modeling the processes of the substances reacting with each other described by the carcasses of the surface spanned by a sheaf of imaginary axis sections bearing onedimensional generators, parameter bearers of 2  surfaces, 3  surfaces, etc.
The purpose of the introductory mathematical practical course is to study theoretical foundations of obtaining work activities´ mathematical models and overlearning surface equations and their geometrical models derivation according to tabulated values of real experimental measurement parameters of multifactorial and multiparameter processes in multicomponent systems.
The core attention in the process of mastering the brief mathematical introduction should be paid to the features of obtaining models incident with sections:
1) 9 experimental points are enough for a sheaf of planes, when to construct the whole studied surface with the required accuracy it is necessary to carry out experimental study in the total space and to obtain its model [5].
2) A sheaf of planes with an imaginary axis needs to have not less than 27 experimental points available to obtain the model and arrange its equation.
In accordance with the curriculum the special course contains as few practical hours based on the results of real research as possible.
To illustrate the abovementioned let us analyse one of the numerous samples of out research. The HAR IHPP12 sewage waters were treated with induction current. Together with that we defined optical density by the agency of a PEC, hydrogen ions´ pressure (pH) by means of an ion meter in the treated water and the HAR control sewage water in fixed time periods (Table 1).
As many parameters, factors and components changed in our research, our equations are sections of a certain multidimensional hypersurface, as a matter of fact.

A combined graphical presentation of the equations (1)(5) in the form of an extended multilevel Radishchev drawing allows depicting a hydraulic ash removal sewage treatment semiparameter technological process under the action of induction currents in threedimensional spatial area graphically and calculating optimal values of the parameters:
t _{opt}=20min, I_{opt.}>2,5Amper, h_{opt.}=4,0 mm
and formulating a conclusion about the total absence of suspended matters in the waters treated with induced currents and the pH value of 7,0; that testifies to approaching to normal properties of the treated waters and the possibility of their being reused for the ashslag pulp transportation. On the research base an application for an invention ("Hydraulic ash removal water purification device") was filed and a patent (№ 2199491) was obtained.
The purpose of the second laboratory course is to study the operating rules and mechanism of standard industrial gauges, which allow performing effective measurements of most important physical and chemical parameters of solutions and acquiring operating skills. In accordance with the curriculum the special course contains as few laboratory hours necessary to acquire practical skills of experimental measurements using pH meter, photoelectric colorimeter and spectrophotometer as possible.
A special attention in the introductory laboratory course should be paid to hardandfast carrying out safety instructions stated in the devices´ service manual. The carefulness in performing all the operations of preparation and carrying out experiments and proper treatment of the devices are of great significance in the obtained measurement results´ objectivity.
The laboratory research purpose is to study manydimensional manifolds in the form of function spaces obtained in the process of experimental measuring of real technological processes´ parameters in multicomponent systems and the formation of skills of practical application of methods of modeling multifactorial and multiparameter technological processes in multicomponent systems.

1. Mathematical modeling of multicomponent mixtures of nonreacting substances.
2. Multidimensional mathematical modeling for the purpose of work activities´ optimization by the example of electric coagulation in sewage waters at their being treated with induction currents.
3. Mathematical modeling of an electrodeless electrochemical process in solutions at their being treated with induction currents and the like [6].
The purpose of research tasks is to reinforce the acquired earlier knowledge on modeling manydimensional manifolds in the form of function spaces obtained in the process of experimental measurements of real technological processes´ parameters in multicomponent systems and to form creative skills of practical application of mathematical modeling methods; for example:
a) Examination and optimization of the operating regime for a pipeline inner surface electrochemical metallization and passivation plant (patents № 2241075and № 2244766).
b) Mathematical modeling of a biochemical process at electrodeless disinfection of environmental waters (patent № 2264992).
c) Mathematical modeling of the chemical coal conversion process (patent № 2272825) and others.
4. Followup study perspectives. The introduction into HEI specialist training of the special course on mathematical modeling of technological processes on the basis of constructive geometry is intended for the formation of an uptodate engineer able to independent exploration, finding and solving scientific and technological problems of sophisticated technology.
The special course is scheduled for 454 hours (90 lecturehours, 108 hours of practice, 46 hours of laboratory research, and 210 hours for term papers among them) from the second to eighth semesters.
