Application of Micro-Flocculation Direct Filtration for Reservoir Water Derived from Yellow River

Article Preview

Abstract:

Aiming at the water quality characteristics of low turbidity and low temperature of the Reservoir Water derived from Yellow River(RWDFYR), the technology of micro-flocculation direct filtration for RWDFYR was studied. The effluent index such as CODMn, UV254, TOC and turbidity was investigated under the different filtration rate conditions of 4m/h, 5m/h, 6m/h, 8m/h and 10m/h. The results show that the value of removal efficiency of turbidity reached at 98%, and the value of removal efficiency of organic matter was 40% also. In this study, the removal effect was good under the filtration rate of 6m/h. Moreover, the removal effect of different filter layers was also carried out. Finally, it concluded that the backwashing cycle of filter layer should not exceed 3days.
