Case Study/Pall’s Rental Filtration System Delivers Fast, Compliant Produced Water Treatment in the Middle East
By PallThe Middle East oil and gas sector is subject to increasingly strict environmental regulations on produced water discharge. Operators must meet oil-inwater (OIW) limits typically ranging from 10 to 40 mg/L,
(10 - 40ppm) with some jurisdictions enforcing even lower thresholds.
Produced water volumes can reach 50,000 barrels per day (332 m³/hr), often at high temperatures (75 °C / 167 °F) and pressures (50 psig / 3.45 barg). Under these conditions, conventional treatment systems—such as gravity separators, hydrocyclones, dissolved air flotation (DAF) units, and biological treatment systems—often struggle to consistently meet compliance standards.
These systems are typically limited by:
• Inefficiency in removing fine or emulsified oil droplets
• Sensitivity to flow rate, temperature, and
pressure fluctuations
• High maintenance requirements and
operational complexity
• Inadequate scalability for high-volume operations
As a result, operators are increasingly seeking more advanced, flexible solutions that can reliably handle variable contamination levels without requiring significant capital investment in permanent infrastructure., making it difficult for conventional treatment systems to consistently meet compliance standards.
