Aeration Bridge System in Huay Kha Khang Canel Rajabhat Maha Sarakham University, Maha Sarakham Province

Abstract

This research introduces the aeration bridge system implemented in the Huay Kha Khang Canal, Rajabhat Mahasarakham University, Maha Sarakham Province, which serves as a community demonstration site. Focusing on water quality enhancement, parameters such as temperature, pH, hardness, total dissolved solids, dissolved oxygen demand (DO), biochemical oxygen demand (BOD5), and total coliform bacteria were studied over 6 months. Results demonstrated improvements in temperature stability (25.48 - 26.12°C) and pH levels (7.21–7.35). The aeration bridge system exhibited notable efficiency in enhancing dissolved oxygen (47.55%) and reducing total coliform bacteria (32.292%). Significant reductions in water hardness (24.82%) and total dissolved solids (12.723%) were achieved. The system showcased a reduction in BOD5 of 11.94%. The study establishes the aeration bridge system as promising for polluted water bodies, emphasizing its impact on key water quality parameters. Further research and optimization are recommended for broader contaminant applications.
