Environ Sci Technol . 2021 Sep; 55(19):13198-13208. PMID: 34546747
Virus destabilization and inactivation are critical considerations in providing safe drinking water. We demonstrate that iron electrocoagulation simultaneously removed (via sweep flocculation) and inactivated a non-enveloped virus surrogate (MS2 bacteriophage)...

Clin Infect Dis . 2015 Jan; 60(8):e36-42. PMID: 25595746
Background: Naegleria fowleri is a climate-sensitive, thermophilic ameba found in warm, freshwater lakes and rivers. Primary amebic meningoencephalitis (PAM), which is almost universally fatal, occurs when N. fowleri-containing water enters...
