• The design of an "Energy Supply System for Water Purification" focused on addressing the issue of untreated sewage contaminating the Mvudi River from the Thohoyandou Wastewater Treatment Plant (WWTW) in Limpopo, South Africa (RSA).

This abstract summarizes an honours design project, the design of an "Energy Supply System for Water Purification" at Thohoyandou Wastewater Treatment Plant (WWTW) in Limpopo, South Africa. The motivation behind this work was the urgent need to address the issue of untreated sewage contaminating the Mvudi River during power outages, particularly in impoverished rural areas.

The project employed a combination of research methods, including an extensive literature review, technical analysis, and design simulations. Various renewable energy options, including solar, wind, and hydro systems, were evaluated. The project concluded that a hydro system was the most suitable solution. MATLAB Code and Autocad Inventor were utilized for turbine design, and Autocad Design Modeller was used for the optimal transmission system design.

The project's conclusions emphasized the significance of implementing the hydro system at the Thohoyandou WWTW and similar plants in the region. The designed system demonstrated the capability to reliably generate a power output of 50 kW, surpassing the daily requirement. Furthermore, the project identified the potential to repurpose excess power, benefiting surrounding communities and expanding purification capacity.

The distinction awarded to this honours design project recognized its contribution to the field of sustainable energy solutions for water treatment facilities. The findings highlight the importance of integrating renewable energy sources to ensure uninterrupted water purification operations and mitigate environmental pollution. The project's results provide practical insights for future research and implementation in similar contexts, emphasizing the feasibility and impact of the hydro system.

In summary, this honours design project effectively addresses the motivations, outlines the research methods employed, and presents compelling conclusions regarding the implementation and benefits of the hydro system for water purification in impoverished rural areas. This is a potential solution that can be implemented in South Africa and some parts of the world facing power supply problems like load shedding.
