Oil & Gas
Efficient Produced Water Treatment & Oil-Water Separation with Advanced Ultrafiltration Technology
Enabling Sustainable Water Management and Efficient Separation in Oil & Gas
The oil and gas industry produces significant volumes of water, particularly produced water — a byproduct extracted alongside oil and gas from underground reservoirs. This water often contains a complex mixture of hydrocarbons, suspended solids, dissolved salts, heavy metals, and naturally occurring radioactive materials (NORM). Effective treatment of produced water is critical for environmental protection, regulatory compliance, and enabling water reuse. Likewise, separating oil-water emulsions is an essential requirement throughout upstream and downstream operations.
FiltMem advanced ultrafiltration (UF) membrane technology delivers robust, efficient solutions for both produced water treatment and oil-water separation.
Water Management Challenges in Oil & Gas
High Volumes
Mature fields often produce more water than hydrocarbons.
Water Composition
Highly variable contaminants based on geological.
Discharge Regulation
Environmental controls over produced water disposal.
Freshwater Scarcity
Operations demand effective water reuse solutions.
Persistent Emulsions
Oil-water emulsions challenge traditional separation methods.
Oily Wastewater
Requiring efficient treatment to meet discharge standards.
FiltMem Ultrafiltration Solutions for Oil & Gas
FiltMem range of ultrafiltration membrane modules, engineered for durability and resistance to harsh conditions and hydrocarbons, provides effective solutions for water management in the oil and gas sector.
Produced Water Treatment
UF can be employed as a primary or secondary treatment step for produced water. It effectively removes suspended solids, oil and grease (especially free and dispersed oil), and some bacteria. This treated water can then be:
Discharged: Compliant with environmental regulations.
Reused: For applications like irrigation, dust suppression, or reinjection for Enhanced Oil Recovery (EOR).
Pre-treated for Desalination: UF reduces fouling in downstream RO systems, improving efficiency in freshwater-scarce regions.
Oil-Water Separation
UF membranes with specific oleophobic (oil-repelling) properties can effectively separate oil-water emulsions. The membrane allows water to pass through while rejecting oil droplets, leading to:
Oil Recovery: Separated oil can be reclaimed and reprocessed.
Oily Wastewater Treatment: Cleaned water is suitable for further treatment or discharge.
Equipment Protection: Reduces fouling and prolongs the lifespan of downstream processing units.
Refinery and Petrochemical Wastewater Treatment
UF can be used to treat oily wastewater generated from refineries and petrochemical plants, removing oil, grease, and suspended solids to meet discharge limits or enable water reuse within the facility.
