The project of purification and desalination of water
Along with the development of intellectual and innovation cluster «NURIS» realizes the breakthrough and strategically important projects, which will give impetus to further technological progress in the country. One striking example is the scientific and technological project "Energy saving technology advanced membranes for water desalination." Author - international scientist, Head of the Laboratory of nano-synergy Zinetula Insepov.
The project is relevant not only for Kazakhstan, which is in last place in the provision of drinking water to the population among the CIS countries, but also for the whole world. According to UN figures, over the past 50 years, the number of drinking water in Central Asia declined by almost 3.5 times. According to calculations of the organization, in 2025 even possible to achieve a critical indicator - 1.7 cubic meters per person per year. The most acute situation on the African continent. However, the lack of drinking water is also observed in some parts of both North and South America. In case of project's success the problem will be solved.
Scientists have set a task to create a new generation of functional membranes based on graphene, capable not only to desalinate water, that is, to separate the water molecules and hydrated ions of salts and other inorganic impurities, but also delay the germs of various bacteria and viruses with a size of 13 nm or more. These actions will make any water suitable for human consumption.
Established nano membrane can later be used for other purposes. In particular, it would be able to clean the biological fluid (blood) from contaminants, viruses and bacteria in a simpler way than currently exist, as well as to purify and separate the various gases.
The technology is more efficient, lower cost of energy and impact on the environment. Nano-membranes and nano-pump will create batteries a longer period of validity, as well as powerful solar plants with an efficiency of more than 42% (at present, only 16% of captured solar energy is converted into electricity). Also with new method it will be possible to save energy in the processing of natural gas and at the same time reduce carbon dioxide emissions of thermal power stations and car exhausts. The use of graphene will allow for information storage is 1,000 times more volume than today's devices to create super-fast computers, flexible, ultra-thin screens, faster planes, as well as to develop new vaccines against cancer.
Thus, the project has great practical interest not only on the desalination of drinking water, but also in the field of new energy sources, hydrogen energy and nano-robots in many industries, as well as nano-medicine and biomedicine, and even in agriculture.
Anchor project is implemented on the basis of two patents of US Department of Energy and the four patents of "Nazarbayev University". In attended by 17 scientists. At the moment, it has already been developed and demonstrated a prototype energy-efficient graphene nano membranes in which fluid movement is provided by a surface acoustic wave. It has been purchased and installed modern equipment for the growth of nanostructured materials, it is the first in Kazakhstan System of Atomic Layer Deposition ALD Fiji and two super servers. For the first time in Astana was created and implemented a supercomputer NUSK-1 with 128 processors. It made the discovery of a new principle of amplification of surface of acoustic waves by using graphene, which is used to move the fluid. Currently, work is underway to further equip the laboratories with the necessary equipment to create the device structures based on them.
About the process of implementation of the project were written 13 articles, five of them are in scientific journals with impact factor and eight are in the materials of international conferences. Also, the project manager monograph was published: Z. Insepov, Cluster ion-solid interactions: Theory, Simulation and experiment, Taylor & Francis, March 2016.
