摘要(英) |
Due to extreme high turbidity during typhoons or heavy rains, which resulted in difficulties in potable water treatment, the water intake well to draw water from upper levels of the reservoir was built in the Shihmen reservoir.
After drawing water from the intake well, it was found that the rapid sand filter was severely clogged, the head loss increased dramatically, and the filtration run-time was seriously shortened. The objectives of this study were first to investigate filter clogging in Ping-Jan Water Treatment Plant while intake water from the water intake well by water quality analysis of different water intake
locations, filter-bed analysis, and pilot study. It was shown that the water qualities from different water intake locations were similar; thus, the water quality was not the cause for the clogging. From the floc retention analysis, scanning microscopy, and energy-dispersive X-ray spectroscopy of filter media, it was found that the particles only deposited on the surface of filter while
intake water from the water intake well. Bubbles observed in coagulation tanks on-site and in coagulation, sedimentation, and filtration units of the pilot, it was
determined that the air-binding is responsible of the filter clogging.
