Despite the benefits, there are also challenges associated with the use of catalysts in aerobic treatment:
Cost of Catalysts: The initial cost of purchasing and maintaining catalysts can be high, which may be a barrier for some treatment facilities. Potential Inactivation: Catalysts, especially enzymatic ones, can become inactivated over time due to various environmental factors such as pH, temperature, and the presence of inhibitors. Regulatory and Safety Concerns: The use of certain metal catalysts may raise regulatory and safety concerns due to potential toxicity and environmental impact.
