The removal of nitrogen compounds in wastewater treatment is a critical process in maintaining environmental standards and preventing eutrophication. This study investigates the impact of thermal conditions on the efficiency of nitrogen compound removal in activated sludge systems. Using a series of controlled laboratory experiments, the study explores how variations in temperature influence key processes such as nitrification and denitrification. The findings indicate that temperature plays a significant role in the activity and growth rates of nitrifying and denitrifying bacteria, with optimal performance observed within a specific temperature range. Higher temperatures accelerated the removal of ammonium, while lower temperatures hindered the denitrification process, leading to incomplete nitrogen removal. The study also discusses the implications of these results for the design and operation of wastewater treatment plants, particularly in regions subject to temperature fluctuations. Understanding the relationship between temperature and nitrogen removal efficiency provides valuable insights for optimizing activated sludge systems and achieving more sustainable wastewater management practices.
