Because ,chlorine gas, is 2.5 times heavier than air, exhaust and inlet air ducts should be installed at floor level. A ,chlorine gas, leak can be found by using the fumes from a strong ,ammonia, mist solution. A white cloud develops when ,ammonia, mist and ,chlorine, combine. Hypochlorination. Combining ,chlorine, with calcium or sodium produces ...

Chlorine,. ,Chlorine, is a greenish-yellow ,gas, with a penetrating and distinctive odor. The ,gas, is two-and-a-half times heavier than air. ,Chlorine, has a high coefficient of expansion. One liter of ,chlorine, liquid will expand 450 times when changing from liquid to a ,gas,. No ,chlorine, containers should be filled to more than 85 percent of their capacity.

In breakpoint chlorination or superchlorination, enough chlorine is added to oxidise ammonia-nitrogen to nitrogen gas. Approximately 10-20 mg/l of chlorine is needed to oxidise 1 mg/l of ammonia-nitrogen. With this method, ammonia-nitrogen levels can be brought down near zero. The effect of chlorine on organic-nitrogen is still uncertain.
