Russian scientists propose to purify water, "exploding" it

Every day on Earth there are fewer and fewer natural reservoirs, the water in which would be suitable for drinking without further purification. Moreover, water that has "worked its way through" in production also needs to be cleaned before recycling. Therefore, the development of methods for filtration and removal of impurities is a rather promising development, and not so long ago scientists from the engineering school of energy of Tomsk Polytechnic University (TPU) proposed a rather nontrivial method of water purification by explosive destruction of droplets.

The first results of the research have already been published in the International Journal of Thermal Sciences, and the studies themselves were sponsored by a presidential grant for young scientists and doctors of science. As the press service of TPU reports,

"The scientific team of the laboratory for modeling heat and mass transfer processes of the Engineering School of Energy of TPU proposed a new way of cleaning industrial wastewater and drinking water from harmful, including toxic and combustible impurities, by explosive droplet destruction. The proposed technology will make it possible to purify water qualitatively and relatively inexpensively. "

For the purification of water itself, it is converted into emulsions, adding water insoluble liquids, as well as in suspension, adding crushed solid impurities. Emulsions and suspensions are injected into the heating chamber, where sharp heating occurs to 300-500 degrees. The pressure drop causes explosive destruction of interphase boundaries, and the process itself proceeds in the form of chain reactions. Due to this, the substrate is rapidly separated into impurities and pure water. According to the project manager Pavel Strizhak,

"When heated, water evaporates, and incombustible impurities precipitate. Thus combustible - burn out. Water vapor condenses and we get purified water. We managed to realize a stable explosive fragmentation of droplets for a group of fluids that are heterogeneous in composition and structure. "
