Abstract
Hydrogen peroxide in a hydrogen peroxide reservoir is supplied to an effluent. Ozone gas generated in an ozone generating apparatus is delivered through branched piping to two ozone supplying points and is supplied to the effluent. The ozone and the supplied hydrogen peroxide react to generate hydroxyl radicals. The hydroxyl radicals react with the materials in the effluent to decompose and remove them.
