dc.description.abstract Access to safe drinking water is not only essential to health, but is stipulated as a basic human right by the World Health Organization. Viruses, infectious intracellular parasites, are a prevalent pathogen and require careful consideration with regard to contamination of water supplies. Over half of hospitalizations, relating to severe diarrhea in children and infants, are caused by gastrointestinal viral infections, resulting from contaminated potable water. Their small size (0.02-0.08μm) and low infectious dose (1-10 organisms) make enteric viruses a difficult microorganism to remove from water supplies, when utilizing mechanical filtration as the sole method of removal. This investigation evaluates the ability of biofilms, and ceramic water filters (CWF’s) to reduce viral contamination of potable water supplies. Bench-scale trials evidenced removal efficiencies between 20 and 70% for biofilms within a parallel plate apparatus, having an aperture of approximately 50μm. Removal efficiencies increased with decreased flow rates and with increased biofilm growth time. Investigations, relating to CWF’s with a pore size distribution of 0.6 -3μm, indicated increased viral removal efficiency with turbid influent water and with partial pore-obstruction. en_US
