| Abstract: | UV_ 254 and COD_ Mn were employed as the indicators of natural organic matters (NOM). Four water treatment processes incorporating biological pretreatment, biological activated carbon(BAC), granular activated carbon (GAC) adsorption, biological filter, photocatalytic oxidation and nanofiltration (NF), were compared for effectiveness in removing NOM from a river water which is the drinking water supply for a large population. The GAC and NF process produced the best treatment results, achieving nearly 100% removal in UV_ 254 and 78.6% removal in COD_ Mn. |
| Keywords: | Drinking water BAC GAC Biological pretreatment UV254 |
