%X Up biological aerated filter(UBAF) was applied for the treatment of source water in Liuwuzhou.Effect of media size on the variation of head loss as well as the removal efficiency of NH3-N and CODMn was evaluated.The results showed that UBAF with media size between 3 and 5 mm was suitable for the removal of NH3-N and CODMn.However,because of the great head loss which also varied significantly before and after back wash,this media size was not favorable for UBAF operation.UBAF with media size between 6 and 10 mm made good performance,and the removal efficiencies of CODMn and NH3-N were 73.8% and 18.6%,respectively,which meet the requirement of the Sanitary Standard for Drinking Water(GB5749-2006).The head loss was low(below 0.4 m) after operating for 24 h.And the variation of head loss before and after back wash was minimal(below 5 cm).Additional test demonstrated that media broken might result in the change of size gradation and the head loss increased subsequently.
