Water Filtration System
- Developed a multi-stage water filtration system to reduce salinity and iron contamination, providing safer household drinking water for Mekong Delta communities.
- Integrated activated carbon, sediment filtration, ion exchange/RO membrane, Arduino/ESP32, TDS and pH sensors, tested by 60 users and refined through 55 feedback responses.
- Donated the system to Dong Yen 3 Primary School, An Giang, enabling continued field testing and further development of affordable clean-water technology.
