Effects of decreased release of chlorinated compounds on water use

Pulp bleaching is usually accomplished in sequential stages using a combination of chemicals. It is common for the pulp to be washed between stages to remove spent chemicals, dissolved lignin, and other soluble products. After use, this wash water is discharged and represents the bulk of the effluent discharge from the bleach plant and is often a significant part of total mill discharge. Partial or complete counter-current circulation of wash water (i.e., circulation from latter stages to earlier stages) is a common water conservation practice.
