Engineering examination as the basis for the successful reconstruction of natural and waste water treatment facilities

Summary

During the operation of natural and waste water treatment facilities, conditions may change in relation to those accepted in design decisions. As a result, the treatment facilities cease to perform the functions assigned to them. Before the reconstruction of such water treatment and wastewater treatment facilities, engineering and technical examination is the basis for making the right technical and technological decisions. The examination involves a decision-making algorithm aimed at achieving the goals set while designing.Through the example of one of the food industry enterprises, the authors considered the positive impact of an extended engineering examination for the acception of correct technical and technological solutions that provide the proper quality of wastewater treatment with optimal capital investments.

Criterial approach to substantiation of the best available techniques for engineering protection against hazardous techno-natural processes

Summary

Prediction of measures and construction of facilities for engineering protection from hazardous processes has a number of specific features that should be borne in mind while developing a method for substantiating the best available techniques. The mathematical tools that provide for substantiating the choice of a technology for engineering protection from hazardous techno-natural processes, that can be assigned to the best available techniques, are under development. One of the approaches is presented that allows, on the basis of quantitative assessments, to substantiate the choice of an option of engineering protection against hazardous techno-natural processes. This approach is based on the expert-analytical method for assessing the risk from hazardous natural-technogenic processes that has been widely used in recent years. Mathematical tools have been proposed that provide for reasonably approaching the choice of the best available technique for engineering protection against hazardous techno-natural processes, taking into account the capabilities of the owner, his position in the current situation and development prospects.
