Abstract
An apparatus and method for the controlled chlorination of a water supply in which an alkali metal salt of dichloroisocyanuric acid is dissolved to form a concentrated chlorine solution that is slowly released into the water supply. The apparatus contains an internal standpipe, open to the water supply at its bottom end and having water inlet apertures and solution metering apertures in its wall. The natural circulation of water in the standpipe through the solid dichloroisocyanurate charge contained in the apparatus results in chlorination of the water supply at a rate controlled by the size and number of solution metering apertures.
