DRAUSY permits treatments according to Louis PASTEUR. He stated: "It's not the microbes you should focus on, but the environment. Microbiology will adapt accordingly". With DRAUSY we are able to change the environment by fine dosage of liquid or gaseous agents over kilometers. For Example:

- We change fouling Wastewater in sewage mains from anaerobe into aerobe conditions. Result: no more odor-nuisance, no more H2S-corrosion. 

- We change anaerobe conditions of organic sludge in lakes. Result: mineralizing the organic matters up to 80%. The remaining earth is harmless - no excavation, no pollution, just an environment friendly technology.
