Mozart music may help microbes clear sewage

MELBOURNE - Believe it or not! Musical notes of 18th century maestro Mozart is now being tested whether it can boost the activity of micro-organisms in breaking down biosolids.

A German company is testing a sound system that replicates the vibrations and sounds of the concert hall which, when combined with oxygen, helps break down sewage, according to The Sydney Morning Herald.

The process being tested involves a stereo sound system developed by a private company, Mundus. It claims the sound waves of Mozart’s “The Magic Flute” and “The Marriage of Figaro”, together with oxygen, boost the activity of micro-organisms in breaking down biosolids.

“Mozart managed to transpose universal laws of nature into his music,” a founder of the company, Anton Stucki, was quoted saying.

“It has an effect on people of every age and every cultural background. So why not microbes? After all, they are living things just like us.”

Australian water conservation body Sydney Water said it has been monitoring progress of the trial, looking for performance data before considering any possible application at its sewage treatment plants.

“There has been no scientific testing reported on the performance of this sewage treatment process,” a spokesman for Sydney Water said.

“Nonetheless, Sydney Water will monitor the progress of the German trial to see what, if any, performance data emerge that might be of practical use.

“It is a novel suggestion that Mozart could help microbes perform better, and one that our science and technology staff have not heard before.”

In sewage treatment, the waste water flows to aerated tanks where bacteria consume what they can. With Mozart’s aid, micro-organisms are expected to increase the aerobic degradation of organic matter or the breakdown of organic contaminants when oxygen is present. The procedure has already been tested successfully in Austria last year.
