Log10 reduction value: 1 (baseline) to 3 (maximum) for protozoa, 3 (baseline) to 6 (maximum) for bacteria and viruses.

Filtration

porous ceramic filtration - Log10 reduction value: 4 (baseline) to 6 (maximum) for protozoa, 2 (baseline) to 6 (maximum) for bacteria, 0.5 (baseline) to 4 (maximum) for viruses (Sobsey et al. 2008).

biosand filtration - Log10 reduction value: 2 (baseline) to 4 (maximum) for protozoa, 1 (baseline) to 3 (maximum) for bacteria, 0.5 (baseline) to 3 (maximum) for viruses (Sobsey et al. 2008).
