Solarization (microbiology)

from Wikipedia, the free encyclopedia

In microbiology , one speaks of solarization when sunlight is used to kill pathogens . The technology is based primarily on the UV component of solar radiation. Solarization is used to produce drinking water from contaminated water, especially in remote regions without a centrally maintained drinking water network. In addition, it is also used as an energy-efficient and cost-effective method for treating organically polluted wastewater. A distinction is made between two methods: In photolytic solarization, sunlight is used directly for detoxification. To do this, it must be concentrated in solar collectors in relation to the normal ambient radiation . In the case of photocatalytic oxidation, sunlight is used to activate an added catalyst . In addition to microorganisms, organic pollutants such as pesticides can also be broken down.
