<p>A method for inhibiting microbial growth in a paper processing system which method includes adding alkali bromide to the processing system and is characterised in that a chlorinated isocyanurate is also added to the processing system. The chlorinated isocyanurate preferably comprises dichloroisocyanuric acid or a salt thereof or trichloroisocyanuric acid or a salt thereof. Trichloroisocyanuric acid or sodium dichloroisocyanurate are preferred. The weight ratio of the chlorinated isocyanurate to the alkali bromide in the composition formed in the paper processing system is preferably greater than 3:1. The chlorinated isocyanurate and alkali bromide maybe added to the paper processing system as a single composition.</p> |
