%X Addition of phosphorus as a novel way to improve the performance of bio-ceramic filter for biological pretreatment of source water was conducted. More bacteria grown in raw water and the BDOC of raw water increased when 50 micrograms/L PO4(3-)-P (NaH2PO4) was added alone were clear evidence of phosphorus limitation on bacterial growth. It shown that about 4.7%, 3.6% and 5.7% more of COD(Mn), UV254 and TOC from the raw water investigated in the experiment on the average was removed respectively when 25 micrograms/L PO4(3-)-P (H3PO4) was added to the influent of bioceramic filter. The role of phosphorus in raw water and drinking water should be paid more attention.
