Abstract

Waste water from pulp bleaching comprising chlorinated phenol, guaiacol and/or abietic acid derivatives is treated with ozone. By treatment with small amount of ozone, e.g. corresponding to 2 kg ozone/ton pulp, the amount of these chlorinated derivatives can be considerably reduced. Reduction degrees of at least 80 % have e.g. been obtained at treatment of waste water from the alkali step of the bleaching process.
