Also, it is well applied in several major areas such as water splitting, bacterial inactivation, and pollutants elimination, which is a possible solution to energy shortage and environmental issues. The fundamental knowledge and the frontier research progress in typical photocatalytic materials, such as TiO2-based and non-TiO2-based photocatalysts, are included in this book. Methods to improve the photocatalytic efficiency and to provide a hint for the rational design of the new photocatalysts are covered.




Recent Advances on Nitrification and Denitrification


Book Description

Nitrification and denitrification are essential processes for the aquatic ecological system and vital for human health. While ammonia is applied for disinfection together with chlorine to produce chloramine, excessive ammonia may cause nitrification and bacteria growth in the water transmission pipeline. Since excessive discharge may cause eutrophication and deterioration of the aquatic system, nitrate is regulated for wastewater discharge in sensitive areas. Further, nitrate needs to be monitored and controlled in drinking water treatment to protect against methemoglobinemia in bottle-fed infants. Various conventional technologies exist, such as adsorption, ion exchange, photocatalytic oxidation, air stripping, biological nitrification and denitrification, and so on, to remove nitrogenous compounds from water. Since ammonia and nitrate are important constituents in fertilizers besides phosphorus (P) and potassium (K), nutrient recovery is drawing attention to maintaining the supply of reliable and sustainable fertilizers. This book provides a comprehensive overview of nitrification and denitrification.
