Formation of fouling deposits is a serious problem facing paper mills. Despite the search for alternative methods, chemical biocides still represent the chief countermeasure to control microbial growth and general fouling buid-up in pulp and paper mills. The purpose of this work was to determine the effect of two biocides (carbamate and glutaraldehyde) on both planktonic cells and fouling layers of a paper mach...

The paper focuses on biofilm development in paper and pulp mills. A carbamate-based biocide was used to modify the surface properties of the microbial cells in order to promote their attachment to the cellulose fibres and to preventing the bacteria from developing biofilms on the equipment. About 75 % of the cells were retained by the fibres. The effect of glutaraldehyde was also tested and it was concluded tha...

Retention of bacteria by cellulose fibres as a means of reducing biofouling in ...

Pereira, M. O.; Vieira, M. J.; Beleza, V. M.; Melo, L. F.

The effectiveness of a non-oxidising biocide (a carbamate-based solution) as a retention agent for cells of Pseudomonas fluorescens in a paper pulp suspension was studied, as a way to reduce biofouling in pulp and paper production processes. The results indicated that the addition of the biocide not only changed the pH of the paper pulp suspension, but also shifted the surface charges of the bacterial cells fro...
