- Abstract:
- A novel adsorbent was applied to enhance the removal of two typical odor?causing compounds including 2-methylisoborneol (2-MIB) and geosmin (GSM) to address drinking water quality issues arising from these two substances in raw water. The influence of key operational parameters, including adsorbent dosing method (wet vs. dry), dosage, and humic acid concentration, on the removal efficiency of 2-MIB and GSM was systematically investigated, and the practical applicability of the approach was experimentally validated. The wet dosing method employing the novel adsorbent demonstrated a more effective removal performance for 2-MIB and GSM. As the adsorbent dosage increased, the removal efficiencies of both compounds exhibited a consistent upward trend. When the dosage exceeded 10.0 mg/L, the removal efficiencies for both compounds surpassed 80%. The presence of organic compounds in water, such as humic acid, exerted a moderate influence on the removal efficiency of 2-MIB and GSM; however, this interference remained generally within acceptable limits. Emergency treatment measures were implemented upon detecting a GSM concentration in the raw water of a water purification plant in Liaoning Province ranging from 400 ng/L to 600 ng/L, resulting in favorable outcomes.
