Objectives: The purpose of this study was to investigate the effect of BIO-CLOD on advanced wastewatertreatment for enhanced removal efficiency and meeting the stringent discharge water requirements of wastewatertreatment plants. Methods: Two experimental apparatuses consisting of anaerobic, anoxic and aeration tanks were operated. Oneincluded a BIO-CLOD cultivation tank. Organic and nutrient parameters and removal efficiency were analyzedby pH, BOD, CODcr, SS, T-N and T-P. Results: The average removal efficiencies of BOD, COD and SS from the apparatus with BIO-CLOD tankinstallation were 95.5%, 88.6% and 92.9%, respectively, and these were higher than the results from theapparatus without BIO-CLOD. The average TP removal efficiency with BIO-CLOD tank marked 56.0%, higherthan the 47.3% from the apparatus without one. BIO-CLOD showed a higher performance for TN removal at49.6%, compared to the result without BIO-CLOD of 34.3%Conclusion: By reaction with BIO-CLOD, ammonia removal was effective in the aeration tank, as wasphosphorus release in the anaerobic tank. Phosphorus luxury uptake and nitrification in aeration tank proceededsmoothly. The application of BIO-CLOD can improve the decrease of odor and settleability of activated sludge ina wastewater treatment plant, as well as increase the removal efficiency of organic and nutrient materials in water.
