Abstract (en)
[origin: WO9614464A1] Method associated with bleaching chemical paper pulp, in which a pulp suspension is brought into contact with an ozone-containing gas, after which a residual gas (6), having a partially remaining ozone content, is separated off from the pulp suspension. The ozone-containing residual gas is subsequently utilized for odour treatment of malodorous condensates (8), with relatively low COD-content, which are obtained when producing paper or paper pulp.
