Учёные предлагают очищать воду пузырьками углекислого газа (3 фото) The problem of treating wastewater from pathogenic bacteria found an original solution using a technique developed at the University of New South Wales in the Australian city of Canberra. Malicious microbes are destroyed by hot carbon dioxide passing through polluted effluents. The method showed high efficiency at low cost. The method is quite simple, for this, in a tank with contaminated water, hot carbon dioxide is supplied from below. Hot bubbles rush to the surface, destroying all harmful microbes along the way. To ensure the destruction of harmful fauna, the temperature of carbon dioxide should be in the range from 100 to 205 degrees Celsius. Savings are achieved due to the fact that it is much easier to heat a small volume of gas than to boil an entire tank with dirty water.

In addition, the gas itself is a technological waste released into the environment. During the cleaning process, contaminated water is heated to only 55 ° C and chemical reactions with the release of harmful substances do not occur. Carbon dioxide after cleaning comes to the surface and can be collected for reuse. There is no need to install compressors to create additional pressure – the gas simply heats up. The first testing of the methodology took place during the treatment of sewage from a pig farm. Учёные предлагают очищать воду пузырьками углекислого газа (3 фото)
