Papermaking yields blackwater and whitewater, laden with fiber, salts, pigments, and tough-to-degrade compounds like lignin and cellulose. Treatment involves various steps to meet discharge standards.

With high COD and color, arises from cotton, hemp, and chemical fiber processing. Treatment involves hydrolysis, biological oxidation, and charcoal to tackle color and organic matter.
