Abstract

Conventionally, activated sludge process (ASP) is most commonly employed for wastewater treatment. However, the conventional treatment system is inefficient for the removal of biological nutrient to greater extent. Nutrients such as nitrogen (N) and phosphorus (P) has high influence on the receiving water body, cause eutrophication and algal bloom. It leads to reduce of dissolved oxygen (DO) level and in turn high risk to aquatic life. Eutrophication is a major problem in developing countries and is responsible for water pollution. Removal of biological nutrient in the wastewater is an essential task to lead the positive impacts on solving the environmental pollution issues. Developing the biological nutrient removal approach in the wastewater treatment to balance the biogeochemical system of the receiving aquatic environment. Biological nutrient removal is a challenging task and number of operational parameters governs its efficiency. This chapter focusses on recent development in the biological nutrient removal and governing factors of the process.
