On the project

Odpadní vody obsahují sloučeniny narušující endokrinní systém živočichů. Současné chemické či termální metody pro jejich odstranění jsou nákladné, a proto zřídka používané v čistírnách odpadních vod (ČOV). Důsledkem je zvyšující se koncentrace estrogenních hormonů ve vodě s velmi vážnými následky pro biodiverzitu a stabilitu vodních ekosystémů. Navrhovaný projekt se zaměřuje na využití mechanismů hydrodynamické kavitace (HC) v kombinaci s pokročilými oxidačními technologiemi (AOT) pro destrukci těchto těžko odbouratelných molekul. HC podporuje produkci hydroxylových radikálů, je schopna pracovat s velkými průtoky a přitom je energeticky optimální a aplikovatelná v každé ČOV.

Description in English
Aquatic ecosystems are polluted by endocrine disrupting compounds from wastewaters. Current methods for removal of estrogenic compounds are based on cost demanding chemical/thermal treatment, which is therefore abandoned by most wastewater treatment plants (WWTP). It results in increasing levels of estrogenic hormons in water with serious effects on biodiversity and stability of ecosystems. Proposed project is focused on the mechanisms of the hydrodynamic cavitation (HC) in combination with advanced oxygenation technology (AOT) for destruction of the persistent molecules. HC enhances production of hydroxyl radicals and is able to process large bulks of wastewater, yet it is robust and energy-optimal technology, applicable in any WWTP. Destruction rate of the selected estrogen will be analysed by LC-MS/MS basic principles. Mechanism for optimal arrangement of the device for removal of estrogenic compounds will be described and published. Fundamental research of combined HC and AOT effect on estrogenic hormons destruction will be carried out by a joint team of engineers and chemists.
