Is chlorine used in water treatment?
“Pure chlorine” is seldom used for water treatment. The three most common chlorine-containing substances used in water treatment are chlorine gas, sodium hypochlorite, and calcium hypochlorite. The choice of the chlorine type to be used often depends on cost, on the available storage options and on the pH conditions required. Chlorination affects pH and pH affects results—a fact that is commonly overlooked in residential water treatment.
Why is chlorine used as a disinfectant?
Chlorine and pH. In general terms, the lower the pH of the water, the more effective chlorine is as a disinfectant. Again, speaking generally, a reason for dosing effectively is that chlorination raises the pH of water, so overdosing often raises the pH to levels where chlorine does not work effectively as a disinfectant.

Does chlorine raise the pH of water?
In general terms, the lower the pH of the water, the more effective chlorine is as a disinfectant. Again, speaking generally, a reason for dosing effectively is that chlorination raises the pH of water, so overdosing often raises the pH to levels where chlorine does not work effectively as a disinfectant. More is not always more powerful.
Which is more effective for disinfecting: chlorine or hypochlorite?
Chemically, this has to do with the relationship between the two constituents of chlorine that together are often referred to as “free chlorine”—hypochlorus acid and hypochlorite ions. Hypochlorus acid is the more effective disinfectant and it dominates at lower pH levels, so a lower pH is preferred for disinfection.

How does chlorine dioxide affect bacteria?
Chlorine dioxide reacts with the organic substances in bacterial and microbial cells, interrupting many of its internal processes. It also combines with amino acids to hamper protein synthesis in the organism . Viruses are killed by chlorine dioxide combining with peptone, a water-soluble product of hydrolysis of proteins into amino acids, thus preventing protein synthesis in the cells. It is much more effective as a biocide than other gases like ozone or chlorine.
