Treatment of polluted surface water from Yellow River (China) with high-density sedimentation tank and ultra filtration : Pilot scale studies

摘要

The Yellow River in China is being polluted with artificial pollution, which brings great challenges to drinking water treatment plants along the Yellow River. The conventional treatment processes could not ensure satisfactory quality of drinking water, and the innovative processes are crucial for the achievement of the newly issued drinking water standard (GB5749-2006).Ultra filtration (UF) technology is a new, more effective water treatment technologies, polluted Yellow River water was used as the raw water for UF study. In this experiment, high-density sedimentation tanks and UF technology were combined, the results show that the combination process is effective in removing turbidity, algae, bacteria, CODMn etc. in long-term process can ensure safe, reliable operation.
