Hydrogen Peroxide for Refinery, Oil and Gas Wastewater Treatment


Reduced Sulfur Compound Treatment for Refinery Wastewater

Sulfur compounds, such as hydrogen sulfide (H2S), thiosulfates and mercaptans, can present serious refinery wastewater problems. Hydrogen peroxide (H2O2) treatment is a cost effective way to treat these reduced sulfur species.


Supplemental Dissolved Oxygen to Reduce BOD and COD

Hydrogen peroxide has been used to reduce BOD and COD in refinery wastewater for many years. This includes:

  • Supply of Supplemental Dissolved Oxygen (DO) when biological treatment systems experience temporary overloads or equipment failure.
  • Predigestion of wastewater which contains moderate to high levels of compounds that are toxic, inhibitory or recalcitrant to biological treatment.

As indicated by these examples, hydrogen peroxide can be used as a stand-alone treatment or as an enhancement to existing physical or biological treatment processes, depending on the situation.

High Strength Wastewater Pretreatment

Hydrogen peroxide is one of the most versatile, dependable and environmentally compatible oxidizing agents. The relative safety and simplicity of its use as an oxidizing agent has led to the development of a number of applications in refinery wastewater systems.
