The formation of hydroxyl radicals

Every day we consume and swallow, prescribed by the doctor or voluntarily, hormone preparations, antibiotics, antihistamines, painkillers, sleeping pills, stimulants, neuroleptics, vitamin preparations and food supplements.


Some of these preparations are excreted by our bodies, and they enter our wastewater treatment plants through the sewage system.

There is no standardized procedure to disinfect, oxidize or eliminate the above mentioned substances.

APW masters and generates cavitation in a controlled process.


The implosion of the cavitation bubbles releases large amounts of energy (5,000 °C / 1,000 bar) in a very small space (micrometer) in relation.

The thermal energy released is the catalyst that triggers the formation of hydroxyl radicals (O2H+) from the monomeric oxygen (O) and water molecules (H2O) dissolved in the water.

These hydroxyl radicals are approx. 2,000 times more powerful than chlorine in their disinfection effect.



The hydroxyl radicals oxidize (disinfect) o.a. residual substances, rendering them ineffective and thus biologically inactive degradable substances.

Only in the combination of controlled cavitation and oxygen enrichment can hydroxyl radicals be produced very efficiently and in large quantities (500% above the amount of oxygen naturally dissolved in water).

This process is patented.
