ABSTRACT:
The invention relates to a method for reducing slime and film formation in plants in which the water of paper and pulp machines is circulated and in plants in which cooling water is circulated. By adding specific nutrients one influences the growth of the mixed microorganism population present in the circulating water, i.e. shifts it in favor of the microorganisms which do not form slime and film.
