For wastewater such as solids control separation wastewater, high-solids industrial wastewater and oilfield wastewater, a customized integrated solution of “specialized water treatment chemicals + integrated water treatment equipment” can achieve:
- Modular, combined and integrated wastewater treatment equipment with a small footprint.
- Process technology method including pretreatment (alkali adjustment/partial desalination) + dissolved air flotation (oil removal) + AAO + MBR + advanced treatment, etc.
- An integrated solution combining chemicals and water treatment equipment.
- Treated water meeting international/domestic direct discharge standards.
- Improved purification efficiency, lower overall disposal cost and reduced environmental impact.
