Electrochemical water treatment is a promising alternative for small-scale and remote water systems that lack operational capacity or convenient access to reagents for chemical coagulation and disinfection. In this study, the mitigation of viruses was investigated using electrocoagulation as a pretreatment prior to electrooxidation treatment using boron-doped diamond electrodes. This research is the first to investigate a sequential electrocoagulation-electrooxidation treatment system for virus removal. Bench-scale, batch reactors were used to evaluate mitigation of viruses in variable water quality via: a) electrooxidation, and b) a sequential electrocoagulation-electrooxidation treatment train. Electrooxidation of two bacteriophages, MS2 and ΦX174, was inhibited by natural organic …

Dissertations (1934 -)
Waterborne viruses are ubiquitous in the environment and present a global threat to public health. Previous research has suggested that iron-based water treatment has promise as a low-cost, non-toxic means of virus mitigation. In particular, zero-valent and ferrous iron have shown evidence of inactivating bacteria and viruses. The purpose of this research was to elucidate the relationship between iron oxidation and virus inactivation and determine if iron-based inactivation can enhance two water treatment processes, electrocoagulation and electrooxidation, for virus mitigation. This research first investigated bacteriophage inactivation due to ferrous oxidation in batch tests using ferrous chloride salt. Ferrous iron oxidation …
