Sažetak
Ecological processes that are happening in the nature arc under strong influence of human act and behaviour (consciously or no consciously), having great consequences for different eco-systems. Transforming the fitted discontinuous distributions to continuous solves the problem of modelling the continuous processes, for which the observed values were measured in discontinuous time periods. One of asymmetric threats today is a terrorist act by which the terrorist (s) can contaminate the origin of the drinking water. Waters are in ecological point of view the most harmfid and vulnerable, but also the most important part of the Global eco-system. On the planet Earth, land makes 29.2, and water 70.8 percent. There are 1.38 billions cubic kilometers of water, out of which97.4 percent is salt water, and 2.6 percent fresh water ; out of this, only 3 percent is potable water. The aim of this work is modelling of ecological appearance with the special emphasize to the water purification. Using the simulation modelling methods and techniques, matched for discontinuous processes, the efficiency of different absorbing materials (active carbon, zeolite A, zeolite ZSM-5, TMAZ) that can be used with different pollutants (dibutyl sulphide. different arsenic substances, different organophosphorus substances). With all collecting data it is possible to predict use of these materials in the accidents and in the situations of terrorist acts. To control the entering parameters and to get the output simulation method we used one of the standard packages for discrete simulation, Service model v4.2 (ProModel Corporation, while for continuous control of the processes we used Extend v4 (Imagine That. Inc.).
