Optimization of denitrification process in treating wastewater containing nitrate nitrogen
Nitrate-nitrogen (NO₃⁻-N) can be a source of the adverse implications to the groundwater. Thus, treatment of wastewater containing NO via denitrification is important to alleviate the deleterious effect of NO₃⁻-N. This study reported the optimization of glucose and sucrose mixture served as a carbon...
