Innovation of flotation through implementation of nanobubbles and optimization of flotation process for water management applications

The project deals with the optimization of dissolved air flotation and induced flotation processes applied in water management (drinking water treatment, wastewater treatment) and their innovation in order to achieve higher efficiency and energy savings. The project will construct semi-operational flotation units combining different methods of air bubble generation (pressure flotation, mechanical gas injection using porous plates or multiphase pump). The whole process will be extended by an innovative element in the form of the implementation of nanobubbles, whose properties will be exploited to achieve a higher separation efficiency of the whole process. The project will make a major contribution to expanding the knowledge of the influence of input conditions on the flotation process in real applications. The knowledge gained will lead to process optimisation and allow easy adaptation of the technology to the nature of the incoming water and to the specific needs of the customer. The main output of the project will be a proven technology combining standard processes of air microbubble flotation with nanobubble flotation, applicable to drinking water treatment and industrial wastewater treatment (food industry (dairies, slaughterhouses, poultry and meat plants), petrochemical industry, paper industry) Translated with www.DeepL.com/Translator (free version)
