Industrial Effluent Treatment Plant for Sustainable Oilfield Operations in Romania
WABAG developed a first-of-its-kind produced water Effluent Treatment Plant at the Suplacu de Barcau oilfield for OMV Petrom SA, Romania’s largest oil and gas producer. Designed specifically for upstream oilfield conditions, the Effluent Treatment Plant treats produced water rich in non-biodegradable organic compounds and complex contaminants released during crude oil extraction. The Effluent Treatment Plant supports long-term resource efficiency by enabling environmentally safe discharge and reducing the ecological footprint of oilfield operations.
Tailor-Made Effluent Treatment Plant Solution Built for Romania’s Largest Oilfield
Every produced water stream in oilfields is unique. To address the demanding characteristics of the Suplacu de Barcau oilfield effluent, WABAG engineered an Effluent Treatment Plant scheme that integrates physical, chemical and biological processes with advanced filtration and adsorption. This custom-designed Effluent Treatment Plant ensures high treatment efficiency and compliance with stringent environmental discharge norms. The Effluent Treatment Plant is optimized for continuous and reliable operation under variable field conditions.
Multi-Stage Treatment Process for High-Performance Produced Water Management
The Effluent Treatment Plant treatment scheme incorporates:
- Equalization
- Coagulation and flocculation
- Dissolved air flotation (DAF)
- Cooling towers (55°C down to 35°C)
- Biological treatment (activated sludge process)
- Lamella clarifiers and dual media filtration
- Activated carbon filtration for extended COD removal
- 2-phase centrifuge sludge dewatering
The multi-barrier approach within the Effluent Treatment Plant ensures robust removal of oil, suspended solids and refractory pollutants. Through this integrated Effluent Treatment Plant, safe discharge is achieved while maintaining regulatory compliance. Overall, the Effluent Treatment Plant establishes a benchmark for produced water management in large-scale oilfield developments.
Supporting Environmental Compliance and Cleaner Oil Production
By treating produced water before discharge, the Effluent Treatment Plant significantly reduces the pollutant load on the environment. With an output of up to 1,000 t/d, the Effluent Treatment Plant supports clean operational practices for Romania’s largest oilfield, demonstrating OMV Petrom’s commitment to responsible resource management. The Effluent Treatment Plant plays a central role in minimizing environmental impact from crude oil production.
EPC Delivery for a High-Complexity Industrial Effluent Treatment Plant
The Effluent Treatment Plant project scope included:
- Detailed design and engineering
- Equipment supply
- Construction, installation and testing
- Site commissioning and handover
Delivered on a turnkey basis, the Effluent Treatment Plant ensures complete lifecycle integration and operational readiness. The Effluent Treatment Plant was engineered to meet strict performance and compliance requirements under complex operating conditions.
Advanced Treatment Technologies for the Effluent Treatment Plant
The Suplacu de Barcau produced water Effluent Treatment Plant incorporates:
- DAF and physico-chemical treatment
- Cooling tower-based temperature conditioning
- Activated sludge biological system
- Dual media filtration and activated carbon adsorption
- Mechanical sludge dewatering
These technologies provide a strong and reliable solution for one of the most challenging wastewater streams in the Oil & Gas industry, positioning the Effluent Treatment Plant as a best-in-class reference.
Measured Environmental and Operational Impact of the Effluent Treatment Plant
The Effluent Treatment Plant enables the safe discharge of treated effluent into the natural environment, ensuring full compliance with regulatory norms. By significantly reducing pollutant loads associated with crude oil production, the Effluent Treatment Plant improves the overall environmental footprint of oilfield operations. In addition, the Effluent Treatment Plant reduces dependency on freshwater sources, supporting long-term sustainability and resource efficiency in oilfield operations.
