Biological treatment is an efficient and cost-effective method for removing dissolved and suspended compounds present in produced water from onshore oil field extraction. Treating produced water in the oil and gas industry is an effective approach with the potential to transform this waste into a valuable resource.
General Objectives of Produced Water Treatment in the Oil and Gas Industry:
1. Oil Removal
2. Elimination of Dissolved Organic Compounds
3. Disinfection
4. Removal of Suspended Particles and Sand
5. Elimination of Dissolved Gases (e.g., light hydrocarbons, carbon dioxide, and hydrogen sulfide)
6. Desalination and Removal of Dissolved Salts
7. Hardness Removal
Physical, chemical, and biological methods, either independently or in combination, can address the above objectives for the treatment of produced water in the oil and gas sector.
