Abstract
A gravity flow disinfectant contactor adapted to enhance contact between a disinfectant solution such as chlorine and the water to be treated to effect a more rapid and efficient disinfection activity. The contactor is constituted by a rectangular conduit having a cross-sectional diffusion plane adjacent its inlet within which is an array of evenly-spaced diffuser tubes supplied with the disinfectant solution. The tubes each have a row of equi-spaced holes drilled diametrically therethrough to produce side-by-side opposing jets of disinfectant in the diffusion plane at right angles to the cross-flowing water stream. As a consequence, the water flowing through the conduit is subjected to a dense cross fire of multiple jets of disinfectant that are uniformly distributed throughout the diffusion plane and quickly interact with the water within a relatively short downstream distance.
