A brewery was experiencing peaks and valleys in their discharge limits.
After using enzymes, the plant reported:
-
Peaks and valleys seemed to even out due to a stronger bacterial balance
-
DO was easier to maintain
-
Discharge limits remained more consistent
-
Odor was no longer a problem
The plant manager provided the following effluent analysis:
