The Effect of Moving Bed Biofilm on the Nutrient Removal Efficiency by Using Enhanced Bardenpho Process

Wastewater is usually treated using various of chemical, physical, and biological approaches to remove phosphorus and nitrogen from it. This study looked at an experimental research that used a lab-scale Bardenpho process to evaluate the elimination of nutrients from synthetic wastewater. The purpose of this study is to investigate how HRT affects nutrient removal efficiency at different MBB ratios (0, 10, 20, and 30%) when total HRT is between 9.5 and 17.5 hours and the IR ratio is between 0 and 300%. The results showed a significant improvement concerning the influence of the MBB ratio on COD elimination, and there was a reasonable increase in TN and PO4 elimination as the MBB ratio increased from 0% to 30% and when IR ratio increased from 0 to 300%. Therefore, the optimum MBB ratio and total HRT for this research would be around 30% and 17.5 hr, respectively, with maximum removal efficiencies of 97.97% , 85.33% and 77.78% for COD, TN and PO4 respectively.
