Access to clean and safe drinking water remains a challenge in Ecuador due to water contamination from industrial, agricultural, and urban activities. This study explores advanced water purification technologies applied in Ecuador, emphasizing their effectiveness, implementation challenges, and future potential. The research focuses on nanotechnology-based filtration, electrochemical purification methods, and advanced membrane filtration systems, analyzing their efficiency, cost, and applicability in different regions of the country. Our findings indicate that nanotechnology-based filtration systems, particularly those using graphene oxide and silver nanoparticles, have demonstrated high efficiency in removing heavy metals and microbial contaminants. These systems are particularly effective in rural and remote areas where access to centralized water treatment facilities is limited. Electrochemical purification techniques, such as electrocoagulation and electrooxidation, have shown remarkable results in removing arsenic and other industrial pollutants from mining-affected regions. However, the high energy consumption of these technologies presents a challenge for large-scale implementation without renewable energy integration. Advanced membrane filtration technologies, including graphene-enhanced and forward osmosis membranes, have been successfully applied in urban water purification systems. These membranes exhibit high selectivity and durability, reducing operational costs in the long term. Pilot studies in Guayaquil and Quito have demonstrated significant improvements in water quality, with reductions in heavy metals, bacteria, and dissolved solids by over 90%. However, the initial investment costs remain a barrier to widespread adoption. Despite the promising results, several challenges hinder the full implementation of these technologies in Ecuador. Limited funding, lack of technical expertise, and insufficient regulatory frameworks slow down the adoption of innovative water purification systems. Government policies and international collaborations play a crucial role in bridging these gaps by providing financial support, research incentives, and capacity-building initiatives. This study concludes that while new filtration technologies offer substantial improvements in water quality and public health, their success depends on a multifaceted approach involving technological advancements, policy development, and community engagement. Future research should focus on cost reduction strategies, hybrid purification systems, and energy-efficient solutions to enhance the sustainability of water treatment initiatives in Ecuador. The integration of renewable energy sources with electrochemical purification and membrane filtration could further improve the feasibility of these technologies for widespread use. Ultimately, a coordinated effort between the government, private sector, and local communities is essential to ensure clean and safe water access for all Ecuadorians.
