Elimination of viruses, bacteria and protozoan oocysts by slow sand filtration.
Water Sci Technol

Article Synopsis
- The research examined how effective slow sand filters (SSF) are at removing viruses, bacteria, and Cryptosporidium oocysts, using data from full-scale systems and lab experiments.
- DEC for viruses was found to be between 1.5-2 log10, with better removal of E. coli (2-3 log10) compared to Campylobacter.
- While lab tests showed high removal rates for specific bacteria and oocysts, full-scale filters were less efficient, likely due to continuous loading, and other factors like the schmutzdecke (a biofilm layer) improved microorganism removal through mechanisms like straining and adsorption.
