Abstract
The present invention relates to an upstream ozone contact tank for removing residual ozone. The upstream ozone contact tank includes an inlet through which purified raw water flows, at least one contact chamber, at least one reaction chamber, an upstream contact chamber, and an outlet that discharges ozone-treated raw water. Especially, the invention provides an upstream contact chamber between the reaction chamber and outlet, wherein the upstream contact chamber includes carbonaceous filter media mounted on a porous plate. An openable gate unit is installed at the lower part of a panel partitioning a final reaction chamber and the upstream contact chamber and controls flow rate. Additionally, the invention enables upstream flow of the raw water flowing into the upstream contact chamber from the final reaction chamber so that the raw water may pass through the carbonaceous filter media upwardly.
