Technical Core and Distinctive Advantages

Are you still grappling with high electricity costs, frequent consumable replacements, complex pretreatment requirements, and stringent influent water quality specifications in oilfield produced-water treatment? The answer is here: we are proudly introducing our “3-Free Direct Filtration” + UF ultrafiltration skid-mounted integrated system—a game-changing technology that redefines the new standard for on-site produced-water treatment and reinjection in the oil industry!

I. Pain Point Analysis: Is your produced water treatment currently facing these challenges?

· Are operating costs stubbornly high? The power system is a “power hog,” with filter cartridges and membrane elements requiring annual replacement, making maintenance expenses a heavy burden.

· Is the process chain lengthy and complex? From pretreatment to fine filtration, there are numerous pieces of equipment, a large footprint, and intricate process management.

· Stymied by water-quality fluctuations? Significant variations in influent water quality lead to poor system adaptability, frequent adjustments, and unstable effluent quality.

· Difficulties in deploying remote well sites? Traditional methods are slow to deploy, require extensive infrastructure construction, and fail to meet the need for rapid production start-up.

If any of the above resonates with you, then you need to learn about our solution.

II. Solution: Disruptive “3-Free Direct Filtration” Technology + UF Skid-Mounted Integrated Equipment

Leveraging decades of technological expertise, we have developed a revolutionary “3-Free” direct filtration technology and integrated it with proven ultrafiltration technology to create an all-in-one skid-mounted system.

Key Highlight: What Exactly Are the “3-Free”?

1. Power-free water production | Zero electricity consumption, 100% energy savings

· Technical Principle: An innovative “direct filtration” system that harnesses the residual pressure of the wellhead inflow as the driving force, eliminating the need for an additional booster pump.

· Customer Value: By completely eliminating the electricity consumption associated with water production, this solution delivers substantial energy-cost savings over the system’s entire lifecycle—making it particularly well-suited for remote areas with high electricity prices.

2. No consumable replacements | Core filter element requires no replacement for life

· Technical Principle: Utilizes specialized filter media that offers high strength, excellent fouling resistance, and long-lasting flux. The unique online combined air–water backflushing technology restores filtration performance, while the core filter element is designed for a service life matching that of the entire system.

· Customer Value: Say goodbye to costly annual filter cartridge and membrane housing replacement expenses! Significantly reduce spare parts inventory and O&M costs, leading to a substantial decrease in total cost of ownership.

3. Non-discriminatory water intake | Adapts broadly to various water qualities

· Technical principle: The system exhibits exceptional tolerance to fluctuations in influent water quality, including suspended solids and oil content. It requires no complex pretreatment or conditioning and can directly treat complex produced water that is difficult to handle with conventional processes.

· Customer Value: Simplifies front-end processes, reduces chemical dosing, ensures confident handling of sudden water-quality fluctuations, guarantees long-term stable operation of the reinjection system, and delivers peace of mind and effortless operation.

III. Process Overview: How Is the Stunning Transformation from “Turbid Inflow” to “Clear Re-injection” Achieved?

Process flow:

Oilfield produced water → “3-Free” direct filtration pretreatment system (removes most suspended solids and oil droplets) → UF ultrafiltration polishing system (deeply removes emulsified oil, fine particles, and bacteria) → Meet-standard purified water → Perfect reinjection

Combined technological advantages:

· “3-Free Direct Filtration” serves as the frontrunner: it effectively buffers water-quality fluctuations, performs coarse filtration and stabilizes water quality, thereby significantly reducing the load on the downstream UF ultrafiltration system.

· UF ultrafiltration as a safeguard: Achieves fine filtration, ensuring that the effluent water quality consistently meets or even exceeds the recommended water quality standards for injection into clastic reservoirs specified in SY/T 5329-2022.

· Skid-mounted integration: All process units are integrated onto one or more standard skids, truly achieving modularity, mobility, and rapid deployment.

IV. Customer Value: What Will You Gain?

· Ultimate Cost Reduction:

· Energy consumption reduced by more than 90% (no-powered water production)

· O&M costs reduced by more than 60% (no consumable replacements, reduced chemical usage)

· Stable and reliable:

· Strong resistance to shock loads, stable effluent quality that consistently meets standards, effective protection of the reservoir formation, and enhanced oil recovery.

· High equipment reliability and fully automated operation enable unattended operation.

· Convenient and efficient:

· “Ready to Use Upon Arrival, Rapid Commissioning”: Upon arrival on site, pipelines can be connected and the system commissioned immediately, reducing the project timeline by 70%.

· “Flexible mobility and reusable design”: After completing service at a single well, the unit can be fully relocated to the next well site, maximizing investment value.

V. Application Scenarios

· On-site treatment and reinjection of produced water from marginal oilfields and scattered well clusters

· Technical renovation, capacity expansion, and efficiency improvement of existing water treatment plants

· Early-stage water injection system for new oilfield development
