This work has been carried out using a process of control, supervision and monitoring of a purification plant intended for the wood Industry. It has been initiated to implement an expert system in the total control of the process and has been complemented with a set of records and alarms. This has revealed in real time the operation state of the process, which allows us to carry out analysis functions, correct them and act appropriately.

The choice of a PLC as a control device, not only has guaranteed the interconnectivity and compatibility of the various equipments through interfaces and protocols, but also has also facilitated the interoperability with the used SCADA implementation. At the same time, there are advantages of allowing using industrial PLC, and especially in this project, it gives flexibility for future upgrades or modifications of the process. The WinCC SCADA with which has been developed the Human-Machine Interface ("HMI") of the system, in addition to its compatibility with the PLC, has helped reduce the processing times of the project due to its versatility and ease of programming.

The reduction of the presence in human staff to a single operator, is not detrimental to the operation of the installation, because the expert system proposed improves the quality of work of the operator and minimizes "human error". All this has an impact on increasing the security of the installation, and in short, prioritises environmental protection, the main objective of this process.

**Visualization the Natural Disasters Simulations** 

Every year, forest fires, floods and landslides cause enormous damage of vegetation and fauna, environment and property and bind significant human resources. Particularly in national parks and natural reservations, unique areas of high degree of protection can be devastated by fire. For instance, during the destructive forest fire in the Slovak Paradise National Park (Slovakia) in 1976, very unique vegetation was destroyed in the Kyseľ Gorge,

Till now (thirty three years after the fire), this locality is closed for tourists because of the vast damages. Topic of a lot of projects is how to prevent such disasters. Our research in institute is oriented on GRID and Cloud computing. A lot of international projects oriented on natural disasters utilize the HPC (High Performance Computing), grid or cloud computing and within such solution raises requirement of visualization service for presentation of the intermediate or final research results. Our basic aim of our research resolved in projects is the creation Visual service for the Modelling and 3D Rendering of Natural Disasters, before Fire, floods and landslides. Changing input data of Fires spread using to generate new outputs very quickly. Grid and actually Cloud computing on a lot of Clusters and On-line 3Dvisualisation service can allow new scenes of Natural disasters spread. Outputs are using for far adjustment to liquidation the Natural Disasters. 3D\_visualization service for animation Natural Disasters should integrate visualization requests of any kind of application solved in our institute and before solved in international projects oriented on environmental problems. The natural disasters like fires and floods or landslides become subject of science in research institutions more and more frequently Many applications from this area are using different kinds of simulation tools, which are producing output data for displaying the results of the computation. The purpose of the visualization service is to model and display results of various simulations of natural disasters like are fire spread in time, fire intensity, flood velocity, landslide activity etc Such service requires unified standards like integration of input data formats and especially creation of unified visualization tool. The purpose of 3D viz. service is to model and display intermediate or final results of various simulations of natural disasters like fire spread in time, its intensity and erosion or floods in time or landslides as well. The output of the service is various scenes of terrain by different simulation outputs. Output of the service can also be the files representing the virtual reality of natural disaster and also files, which are

where the recovery into the former state will last 200 years .
