Pulp & Paper Wastewater

Paper is vital to a vast swath of products and consumer goods—and water is an essential ingredient to the pulp and paper industry. The resulting wastewaters may face some treatment challenges and regulatory scrutiny, in particular due to risks to aquatic life.


Wastewater concerns may include:

  • residual bleaching agents, such as hydrogen peroxide
  • reducing consumption by increasing water reuse
  • total suspended solids (TSS) and turbidity
  • biochemical oxygen demand (BOD/COD)
  • organics (especially organochlorides)
  • ammonia/nitrogen
