Abstract: The protection and reclamation of surface waters, particularly lakes, necessitates the implementation of novel approaches that effectively integrate natural biological processes with sophisticated technological solutions. This paper examines the potential of bioremediation techniques utilising artificial aeration systems, with renewable energy sources serving as a viable power source. The objective of the analysis is to enhance the sustainability of the remediation of aquatic ecosystems. A multi-criteria analysis (MCA) was employed to evaluate the performance and environmental impact of the selected methods. Based on the results of the MCA, the SHPP (small hydro power plant) technology achieved the highest score for both lakes, 0.85 and 0.78, respectively, making it the optimal technology. In comparison, wind energy scored around 0.5 and photovoltaic (PV) around 0.6, showing a poorer fit with local conditions. By integrating reclamation with renewable energy applications, this research presents a strategy for developing more resilient and environmentally sound water management strategies.
