Project summaryLiquid media filtration with different membranes application is becoming one of the leading processes in modern industry and activity connected with environment protection. The leading role of filtration process effectiveness is given to the qualities of membranes applied for this purpose. Though dozens of membrane types are known today, human activity introduces such problems in liquid media cleaning up, which can not be solved with the help of already known membranes.
The aim of this project is development of scientific bases technology of new type of membranes for deep water cleaning up, at first from soluble organic impurities.
To reach this goal the forces of two different scientific schools are combined, one of them is famous for its works in the field of inorganic photocatalyzers, the other- in the field of inorganic metal ceramic membranes development. Together it is supposed to work out scientific technology bases and to create a technology model of metal ceramic photocatalytic membranes which further on may be used in membrane reactors of different design for problem related to water and air purification.
Taking into account abrupt reduction of a number of orders for high temperature corrosion-resistant inorganic membranes from the side of military defense complex of Russia on the one hand and the demand reduction in catalyzers for military technology on the other side, specialists in these fields switched to works in the field of new types of functional membranes in the interests of ecology and civil industry.
New functional multi-layer metal ceramic membranes should not only solve traditional problems such as components separation (for example, oil and water separation, radioactive colloids capture in liquid radioactive waste etc.) but also provide deep water and solutions cleaning up from difficulty removed organic substances. This problem may be solved if in multi-layer metal ceramic membrane upper layer will be a photocatalyzer (high anatase titanium dioxide).
The group of the proposal authors works in this direction from 1991. Invoking scientists from nuclear and defense industries of Russia and also from Russian Academy of Science institutes it was possible to create experimental base, theoretical, calculating and experimental methods which allowed to formulate the concept and start works in the field of new photocatalytic inorganic membranes.
In this project the technology of inorganic photocatalytic membranes production will be worked out, also their characteristics will be studied and possibilities of their usage for deep water purification aims. Also it is supposed to hold large volume of theoretical and experimental studies for perfecting the views on mechanism of titanium dioxide formation, the qualities of which completely coincide with photocatalytic deep water cleaning up problems.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
