Abstract

The invention relates to a method of reducing slime for-mation in plants in which water is recycled, whereby a ligno-sulfonate is added to the water. The lignosulfonate is pro-duced by a special method and has a special composition, which leads to a surprisingly good effect of the added lignosul-fonate.
