AWWA ACE58137

Bacterial Regrowth Potential (BRP) and biodegradable organic carbon (BDOC) measurement were used to investigate thelimiting effect of phosphorus on the bacterial growth in raw water. Addition of phosphorus toimprove organic substance removal in raw water with bio-ceramic filters as the biologicalpre-treatment was studied. The raw water used in the experiments was from a reservoir located innorthern China. Two parallel pilot-scale up-flow bio-ceramic filters were used in the experiments.25ug of PO43--P liter-1 (as H3PO4) was added continuously to the influent of one bio-ceramic filterfor 60 days while another was operated as a reference without phosphorus addition. This investigation indicates the importance ofphosphorus for biological treatment of drinking water. Includes 19 references, tables, figures.
