Abstract

Excessive nitrogenous compounds released into the public water bodies not only result in direct toxicity to aquatic animals, but also increase the overgrowth of aquatic plants resulting eutrophication. Nitrogen pollution has major effects on both human health and the ecological functions of natural ecosystems. This causes a spike in algae growth, which can rapidly deplete the dissolved oxygen in a body of water, causing harm to fish and the surrounding ecosystem. For this reason, it is necessary to study the process of nitrogen removal in wastewater treatment plants in order to remove nitrogen efficiently. The processes of nitrification and denitrification in a sequencing batch reactor. A nitrate test kit and spectrophotometer in order to measure nitrate concentrations throughout the various stages of our reactor cycles. Initially found it difficult to achieve nitrification in our plant. After increasing the dissolved oxygen levels during our aeration stage, nitrate began to be formed. In order to achieve higher levels of nitrification, it was necessary to increase the length of the aeration stage. It was also necessary to increase the length of the anaerobic phase in order to allow for significant denitrification.
