For enhancing and continuing applications of water IoT project with the Ministry of Environment (MOENV), the project team reviewed previous R&D accomplishments and focused on enhancing quality control, expanding the application, conducting diverse field verifications, and exploring commercialization opportunities this year. The main purpose of this project is concentrated on three areas: (1) Optimization and Integration of Water Quality Sensors: Upgraded four compact optical sensing modules, achieving a 1-month field test with 2-3 weeks of autonomous operation, significantly reducing maintenance needs; Conducted a 3-month trial of self-cleaning sensors in Taichung's Dali River, extending maintenance intervals by twofold and reducing labor costs; Analyzed IoT bottlenecks and development trends, proposing applications tailored to MOENV needs; Developed miniaturized IoT heavy metal sensing equipment with design and cost-effectiveness assessments. (2) Diverse Sensor Applications and Efficiency Improvements: Applied LDC and LQ models to analyze Nankan River water quality, identifying point source pollution upstream and significant non-point source increases during rainfall, requiring over 97% pollutant reduction; Conducted energy-saving studies on wastewater plant blower operations using time-based and logic-based controls, reducing energy consumption by 18% and 32%, equivalent to 12-23 tons of annual CO₂ reduction; Trialed drone-based water quality sensing and sampling in reservoirs and rivers, demonstrating comparable results to standard methods and potential for further development; Long-term monitoring data over 10 years showed significant links between pollution control events and water quality improvements, with WQI rising and RPI declining at most sites. Key factors included ammonia nitrogen and total phosphorus from agricultural and domestic wastewater sources. (3) Promotion and Collaboration: Through four collaborative meetings and exhibitions, four published papers, and one U.S. patent application, the team continues to optimize technology and expand project impacts. By tracking progress, ensuring data quality, and fostering cooperation between central and local governments, the project integrates IoT into daily life, enhancing water quality transparency and improving environmental outcomes for public benefit.
