The BAF for wastewater treatment loaded with new ceramic fillers was investigwed in comparison with the BAF loaded with biogenic ceramisite agitator.The feasibility and features of the new ceramic fillers had been analyzed by comparing the two fillers and the operational parameters had been analyzed and determined at the same time.It is shown are that when the average influent CODcr is 135.6 mg/L

NH4+-N 42.1 mg/L and TP 0.69 mg/L

the removal efficiencies of The BAF loaded with new ceramic fillers and ceramisite agitator are 81.2%

99.8%

68.1% and 80.8%

99.5%

66.7% respectively at the condition of the HRT=1.5 h.New ceramic fillers required less water to backwash and had better effect than biogenic ceramisite agitator at the same condition

what is more

the running costs of the BAF loaded with new ceramic fillers were less than that of the BAF loaded with ceramisite agitator.
