Researchers from the University of Lund in Sweden summed up the results of an experiment to propose a new unusual technology for purifying tap water. In 2020, in the city of Varberg, for the modernization of the water management, a complex was made with a biofilm not inhabited by special bacteria. They simulated a biome in the intestines of a person who, under his construction, does not call a set of tubes with biofilms that way.
The main condition of the experiment is that chlorination is completely excluded from the water treatment process. Chlorine is too effective an agent that destroys all microorganisms indiscriminately and is harmful to human health. Therefore, it was decided to confirm the quality of the water if it does not expose it to chlorine.
Scientists took separate six months water samples from different points of the Varberg water supply and collected the composition in them. Within a few months, the picture changed dramatically – the water was filled with life, there were 10 million bacteria in one glass. But after a while, everything changed again – the microbes became much smaller, and one species began to dominate watts. It was Bdellovibrio, a predator that preys on other bacteria and actively consumes even antibiotic-resistant species.
Bdellovibrio bezopasen for humans does not affect some of the microbes that are beneficial to our body, so scientists have come to the conclusion that after such treatment the water is drinkable. The main goal of the experiment reached the possibility – it was possible to find a solution to abandon chlorine in water purification. However, the influence of the new bacterial world in water without bleach on the human phenomenon is not yet sufficient, it will be investigated. continue.
