The physicochemical calculations of the required amount of the GTT grade goptalum catalyst of ozone decomposition and the pressure drop on the catalyst bed under the operating conditions of the gas systems of particle accelerators were presented. The results of calculations were compared with the experimental data obtained in the gas system of the ATLAS detector unit of the Large Hadron Collider. The obtained physicochemical data make it possible to optimize the parameters of ozone filter destructors and the amount of catalyst required for purification of gas mixtures from ozone in detector units of accelerators.

The authors use Kuzbass as the example to study strategic approach and methodology of choosing and implementing vanguard (perspective) physicochemical and biological technologies for water treatment plants. They also examine the requirements for purification and disinfection of drinking and waste waters under present conditions characterized by increased anthropogenic loads. These procedures should be carried out with controlling a number of new types of dangerous contaminants. Currently there is no provision for systematic analysis of their presence in water sources before and after their treatment. The authors study the interrelation between forecasting, strategizing, target programming, project management of planning and realization of the priority of implementation of vanguard physicochemical and biological technologies of vanguard physicochemical and biological technologies for water treatment at the water supply and drainage utilities. In the strategic study the authors adduce the overview of perspective trends of development of vanguard physicochemical and biological technologies and the examples of their technical realization which allow fulfilling the strategy’s priority under study within the set of priorities “Development strategy of life supply systems (water supply and water waste). Water utilities as “green economy” translators”. The article studies the levels of water quality control as well as common approaches to building regional water quality control centres and implementing online water quality control. The authors adduce the main competitive advantages that the Kemerovo region possesses to fulfill the priority. Strategizing of the implementation of vanguard physicochemical and biological technologies will provide the opportunity for realizing long-term (up to 15 years long) target programs in water supply and drainage areas in order to improve the performance of water industry.

The aim of the research is to choose the most efficient adsorbent for two-stage ozone-sorption purification of groundwater containing both trichloroethylene (TCE) and tetrachloroethylene (PCE) betw...

In this research, the ozonation–sorption technology for water purification to remove trichloroethylene and tetrachloroethylene is presented. Physical and chemical (kinetic) parameters of consecutive ozonation and sorption of trichloroethylene and tetrachloroethylene from water are determined. The optimum technological parameters of this method for the purification of water from trichloroethylene and tetrachloroethylene are developed. R&D were carried out using water from 12 underground wells nearby Podolsk, Moscow region (Russia).
