Drinking Water Water treatment plants have evolved their technology over the years to tackle health threats due to water contamination eg cholera, typhoid, and dysentery. Treatment plants began to implement chlorination. 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 "the most significant public health advance of the millennium” from Life Magazine. Chlorination Graphic - Typhoid Fever<unk>  is the next step in the evolution of this process. It chlorinates drinking water without producing environmental toxins. Unlike other chlorination techniques,<unk>  generates no sludge or by-products other than hydrogen which must be managed safely. It is safer for the operators of the chlorinators as there is no handling of chlorine gas, which is highly toxic and corrosive. A risk assessment is required as hydrogen released is flammable & explosive. Swimming pools When a swimmer enters a pool, they add up to one billion organisms to the water. Chlorination kills all organisms harmful to swimmers such as those that cause ear infections and athlete's foot. The advantages of<unk>  in this process are as follows: *Not irritating to skin or soft tissue. *Active in small concentrations. *Longer lifespan of chemical and therefore less replacement necessary. *Easily measurable.
