Model analysis of electroflotation water treatment of wastewater containing microplastics
AI summary Read the abstract
This study developed a mathematical model describing how electroflotation can remove microplastics from wastewater, identifying key factors affecting efficiency. Better process models help optimize treatment systems for removing plastic particles before they enter waterways.
The paper presents a model of the microplastic electroflotation process and considers the factors affecting the efficiency of this process during wastewater treatment. The results obtained will help optimize the microplastic electroflotation process and develop more effective ways to remove plastic particles from the treated water, as well as help in the development of new types of flotation technology that allow several purification processes to be carried out simultaneously in one device. These devices can prevent the destruction of the formed flotation complexes, compared with the use of a traditional cleaning scheme with several autonomous devices installed in series. The results obtained provide a rationale for choosing the most efficient electroflotation apparatus for wastewater treatment from microplastics.
