Abstract
The decimal elimination capacity (DEC) of slow sand filters (SSF) for
viruses, bacteria and oocysts of Cryptosporidium has been assessed from
full-scale data and pilot plant and laboratory experiments. DEC for viruses
calculated from experimental data with MS2-bacteriophages in the pilot
plant filters was 1.5 – 2.0 log. E. coli and thermotolerant coliforms (Coli44)
were
