Affordable and Sustainable Water Purification Solutions for Developing Countries: An Integrated Approach

Access to clean and safe drinking water remains a critical challenge for over two billion people worldwide, primarily in developing countries. This research investigates the effectiveness of low-cost, sustainable water purification technologies and evaluates public perception and readiness for adoption. A combination of experimental analysis and survey-based research was used to identify feasible purification methods, measure contaminant levels, and understand socio-cultural and economic barriers. The study highlights the success of eco-friendly methods such as solar-powered electrolysis and activated carbon filtration. A prototype device tailored to off-grid communities was developed, emphasizing affordability, ease of maintenance, and energy efficiency. Findings suggest that combining technological innovation with community engagement and education can lead to significant improvements in water quality and public health outcomes.
