Chlorinator

an apparatus for discharging chlorine gas and preparing its aqueous solution (chlorine water) that is used in the disinfection of natural and waste waters. There are two types of chlorinators: one in which the gas is metered under pressure and one in which it is metered under a vacuum. The latter, which is the most common, usually consists of a vessel into which liquid droplets, dust, and other impurities from the chlorine gas are deposited, a rate valve, a filter for the final purification of the gas, a pressure-relief valve, a flow meter for the gas, and a mixing tank for the chlorine and water.

The apparatus used in chemical technology for the chlorination of organic and inorganic compounds is also called a chlorinator.
