Also found in: Dictionary, Thesaurus, Medical.
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.
