- Abstract
- This study evaluates the potential of various coagulants to enhance the efficiency of total phosphorus removal facilities in a sewage treatment plant. After analyzing the existing water quality conditions of the sewage treatment plant, the coagulant of Poly Aluminium Chloride was experimentally applied to measure its effectiveness. In this process, the use of Poly Aluminium Chloride and Polymers in various ratios was explored to identify the optimal combination of coagulants.
The experimental results showed that the a coagulants combination demonstrated higher treatment efficiency compared to exclusive use of large amounts of Poly Aluminium Chloride methods. Particularly, the appropriate combination of Poly Aluminium Chloride and Polymers played a significant role. The optimal coagulant combination derived from the experiments was applied in a micro flotation method of real sewage treatment plant to evaluate its effectiveness. This study presents a new methodology that can contribute to enhancing the efficiency of sewage treatment processes and reducing environmental pollution. This research is expected to make an important contribution to improving to phosphorus remove efficiency of similar wastewater treatment plant and reducing the ecological impact from using coagulants in the future.
