摘要
The upflow slow sand filtration system was modified by combined application of a fiber filtration unit above the sand bed of the conventional sand filter. The results obtained from pilot scale filtration experiments conducted for removing turbidity contained in river water from a dam reservoir and tracer particles of Cryptosporidium demonstrated clearly that the modification was very effective in alleviating the deterioration of the filtrate in turbidity induced by rainfall and by cleaning of the sand bed. Its effectiveness in lowering the levels of the tracer particles of Cryptosporidium in the filtrate was also confirmed.
