Electrochlorination

Electrochlorination is the process of producing hypochlorite by passing electric current through salt water.

A low voltage DC current is applied, electrolysis happens producing sodium hypochlorite and hydrogen gas (H2).

The solution travels to a tank that separates the hydrogen gas based on its low density.

Chlorination virtually wiped out both the spread and initial contamination of these diseases, and did so in a way that earned it the title of "probably the most significant public health advance of the millennium" from Life Magazine.

Unlike other chlorination techniques, electrochlorination generates no sludge or by-products other than hydrogen which must be managed safely.

Rates of death due to typhoid fever in the US declined rapidly after water chlorination began.
