Process for controlling and/or degrading undesirable slime formation in recirculated waters

In a recirculated water of the paper industry, slime formation was to be prevented. This was achieved by the content in the recirculated water of microbially degradable nitrogen and phosphorus (limiting of nutrient sources) being increased and matched to each other to the extent that the formation o...

Zusammenfassung:	In a recirculated water of the paper industry, slime formation was to be prevented. This was achieved by the content in the recirculated water of microbially degradable nitrogen and phosphorus (limiting of nutrient sources) being increased and matched to each other to the extent that the formation of viscosity-increasing slime substances is suppressed and/or already formed slime contents are bacterially degraded, if desired living microorganisms and/or enzymes being added as further additives to the recirculated waters.
