Oxidising biocides II, 21. in paper making

Oxidants also provide additional benefits such as enhancing the performance of other biocides. Biocides like isothiazolinone, Bronopol, and DBNPA work much more effectively in an oxidising environment than in a reducing environment. Oxidants can also alleviate anaerobic conditions and decrease the problems caused by anaerobic bacteria such as odors. 

Oxidants such as chlorine, chlorine dioxide, and peroxides are also used as bleaching chemicals and are very familiar to papermakers. 

Even though oxidants can be very effective and are relatively inexpensive biocides, they can also cause problems for the papermaker. Oxidants can corrode the metals used in the paper machine and destroy felts used in the press section. Oxidants can also react with and destroy other chemicals used in papermaking including 

One advantage in using alternate oxidants such as Peracetic Acid (PAA) and ammonium bromide is that these oxidants are generally less detrimental to equipment and other chemicals used in papermaking. 

The main oxidants used for biological control in papermaking are the following
