Optimizing nutrient removal of moving bed biofilm

1/6/2020· Biological processes used for nutrient removal are typically arranged in different configurations (anaerobic, anoxic and aerobic) to achieve the required removal efficiency. However, the high required reactor volume to achieve acceptable treatment performance is considered a major drawback of these technologies, making them economically impractical in terms of fixed capital cost

Biological nitrogen removal from industrial

The removal ratio of total nitrogen was 90% to 98% and that of ammonia was 80% to 92%. In addition, the characteristic equations for biological treatment were applied to this system on the assumption that both reactions of denitrification in the anaerobic reactor and nitrification in the aerobic reactor can be approximated to a first-order reaction.
