INTRODUCTION. Nitrogen compounds are nutrients and are essential to all forms of life. In surface water, concentrations of ammonium nitrogen (NH 4 +-N) exceeding 0.3-0.5 mg/L (eutrophication) can promote the growth of algae and decrease the dissolved oxygen required for aquatic life (Hussain et al., 2007).With increased awareness and understanding of the deleterious effects of nitrogen ...

Application of Red Mud in Wastewater Treatment
Application of Red Mud in Wastewater Treatment

Red mud, (RM) is an industrial waste produced in large amounts during alumina extraction from bauxite. Its disposal generates serious environmental pollution due to high alkalinity. Therefore, a strategy for the effective utilization of RM must be developed. For instance, RM may be transformed into useful products, such as adsorbents. Given its high concentrations of aluminum oxides, iron ...
