Production Systems
Produced Water Treatment
APEX’s advanced produced water treatment system is designed to efficiently remove oil from produced water during development well testing and clean-up operations. Water produced in these phases often contains stable oily emulsions that require effective treatment prior to safe environmental discharge.

APEX’s advanced produced water treatment system is designed to efficiently remove oil from produced water during development well testing and clean-up operations. Water produced in these phases often contains stable oily emulsions that require effective treatment prior to safe environmental discharge.
Our system utilizes compact, skid-mounted vessels equipped with high-performance oil adsorption filter cartridges. These cartridges are engineered to handle a broad spectrum of process contaminants and can be arranged for either parallel or series operation based on the clean-up requirements.
Each vessel is capable of removing up to 72 kg of oil with a separation efficiency of 90–95%, achieving oil-in-water concentrations as low as 5 mg/l. The system’s performance is continuously monitored using an industry-leading oil content analyzer to ensure compliance and operational efficiency.
Note: Designed and manufactured to ASME VIII Div 1, ANSI B31.3, NACE MR-01-75, SI 289, SI 913, EN 12079, BS 449. Other sizes and configurations are available to meet most applications. For more information, contact your local Apex Petroleum Services representative.
