摘要：

Biosand filters (BSFs) are point-of-use water treatment systems that can provide safe and affordable potable water to households in developing countries. However, little information is available on the dynamic performance of BSFs or for selecting local materials for use as filter media. In this study, water quality dynamics, biofilm characteristics, and hydraulic performance were investigated in two full-scale BSFs. Dynamic analysis showed that significant removal of indicator organisms and total organic carbon (TOC) occurred during the pause period between charging the BSFs. Biofilm characterization showed that more particle-associated biomass exists within the BSF column compared with that in the schmutzdecke layer.
