SINOKLE’s Advanced Fracturing Flowback Water Treatment: Achieving Zero-Additive, Low Energy Cost, and Highly Intelligent Solutions for Oilfield Sustainability

In the field of oil and gas development, the treatment of fracturing flowback water has long posed dual challenges in environmental protection and cost management. Its complex composition, high viscosity, and severe emulsification make traditional treatment methods—heavily reliant on chemical additives—not only costly but also prone to secondary pollution and hazardous waste disposal issues.

Faced with China’s increasingly stringent environmental standards and the intrinsic need for cost reduction and efficiency improvement in oilfields, Shenzhen Clear Science & Technology Co., Ltd (SINOKLE), leveraging its independently developed core processes and patented technologies, has successfully driven a paradigm shift in fracturing flowback water treatment, supporting Xinjiang oilfields in China toward a new era of “zero-additive, low energy cost, highly intelligent” high-quality development.

1. Core Technology: Integration of Pure Physical Separation and Advanced Oxidation

SINOKLE’s solution overturns the traditional “chemical-based” approach, establishing a technology system centered on pure physical separation and high-efficiency catalytic oxidation: CDOF (Ozone Catalytic Oxidation for Deep Gel Breaking & Viscosity Reduction) + CDFU (Cyclonic Dissolved-gas Flotation Unit for High-efficiency Oil & Solid Removal) + KFM Filtration, with skid-mounted equipment capable of on-site deployment, producing filtered water suitable for reuse.

· Cyclonic Dissolved-gas Flotation Unit (CDFU): As a domestically pioneering next-generation high-efficiency flotation technology in China, CDFU creatively integrates cyclonic centrifugal separation with ultrafine bubble flotation. Its working principle uses high-speed cyclonic flow to generate strong centrifugal forces that pre-aggregate fine oil droplets and particles in water, while simultaneously producing large quantities of micron-sized bubbles that firmly adsorb pollutants. The combined action of cyclonic separation and buoyancy allows rapid flotation and separation. This technology achieves purely physical demulsification without the need for flocculants, preventing oily sludge generation at the source, with oil removal efficiency consistently above 90%.

· Cyclonic Dissolved Ozone Flotation (CDOF): Targeting hard-to-degrade dissolved organics and residual chemical additives in flowback water, SINOKLE developed the patented CDOF unit. It integrates multiple ozone catalytic oxidation, hydrodynamic cavitation, and cyclonic dissolved-gas flotation. Under pressurized, enclosed conditions, it enhances ozone oxidation efficiency severalfold, rapidly breaking polymeric substances like guanidine-based gels, while simultaneously performing flotation separation. The ozone reaction time is short (≤15 minutes), with utilization rates exceeding 99%, and energy and operational costs reduced to less than 30% of conventional ozone oxidation technologies.

· Key Materials & Modification Technologies: Supporting these processes is SINOKLE’s advanced materials science work, such as atomic layer deposition (ALD) for atomically precise hydrophilic-hydrophobic modification of filter media surfaces, greatly improving filtration precision and anti-fouling capacity.

2. Proven Exceptional Performance

SINOKLE’s innovative integrated processes have been successfully scaled and applied across multiple oilfield blocks in Xinjiang, China, with reliable data supporting their outstanding performance:

In the first Xinjiang oilfield fracturing flowback treatment project, SINOKLE employed the “CDFU + KFM Activated Filter Media” process at a treatment scale of 360 m³/d. The project successfully addressed the industry challenge of gel-breaking at low temperatures, achieving stable all-weather operation and water reuse, substantially reducing chemical and sludge disposal costs for the client.

3. Multi-dimensional Value: Beyond Environmental Protection to Economic Impact

The technological transformation driven by SINOKLE manifests across environmental, economic, and operational dimensions:

· Significant Economic Benefits: The “zero-additive” model eliminates ongoing chemical consumption and costly hazardous waste disposal. The “low energy cost” design reduces long-term operational costs, and skid-mounted modular construction drastically shortens project timelines while minimizing land and infrastructure investments. Overall lifecycle operational costs can be reduced by over 70% compared to traditional processes.

· Reliable Production Assurance: Fully automated intelligent control systems support remote monitoring and unmanned operation, lowering safety risks and labor intensity. Stable treatment ensures reinjection water quality, critical for maintaining reservoir pressure and ensuring stable oilfield production.

· Far-reaching Industry Significance: SINOKLE’s practices offer a green, low-carbon, sustainable path for oilfield wastewater treatment. This responds to national ecological civilization strategies and represents a fundamental shift from passive “end-of-pipe” treatment toward proactive “process resource recovery.”

3. Conclusion

From field validation in the Gobi Desert of Xinjiang to broad application under complex global conditions, SINOKLE consistently leverages robust patented technologies and proven engineering results to define new standards in fracturing flowback water treatment. “Zero-additive, low energy cost, intelligent” is not only a technological commitment but a guiding principle implemented in every project. This represents not merely an upgrade in treatment processes but a concrete step toward integrating environmental and economic benefits for the oil and gas industry, advancing toward high-quality, sustainable development.
