Recently, our company – Tianjin CNCLEAR Environmental Protection Technology Co., Ltd. (hereinafter referred to as CNCLEAR Environmental Protection) – has developed an integrated ultrafiltration system specifically for the oilfield sector. Featuring a modular dual-container design, it integrates high-efficiency operation, environmental adaptability, and intelligent oversight, delivering a reliable technical solution for oilfield fracturing water reuse.

Core Process: High Efficiency & Stability, 2,000 Tons Daily Output

As the system’s core treatment unit, the main container houses 44 high-performance HQ-UFO8060 external-pressure PVDF ultrafiltration membrane modules. It adopts a unique reverse-flow process—with water inlet at the bottom and product water outlet at the top—which not only significantly enhances contaminant rejection efficiency but also achieves a stable daily water output of 2,000 tons, fully meeting the stringent quality requirements for oilfield reused water.

Intelligent Auxiliary System: Multi-layered Protection for Uninterrupted Operation

The equipment container integrates a complete auxiliary system, ensuring long-term stable operation.

Precision Pretreatment: Equipped with micron-grade bag filters to efficiently intercept suspended solids, sediment, colloids and microorganisms, reducing ultrafiltration membrane fouling risk by over 60%.
High-Efficiency Pump Set: Utilizes multistage vertical centrifugal pumps (inlet lift pumps and online backwash pumps) to ensure optimal hydraulic performance of the system.
Intelligent Cleaning: Equipped with a chemical cleaning unit that automatically matches acid-alkali or oxidative cleaning solutions, extending membrane lifespan.

Technical Advantages & Safety Upgrades 

Modular Design: Dual-container structure enables rapid deployment and adapts to complex environments.
Energy Efficiency: Optimized processes reduce energy consumption, reducing operational costs by 40% compared to conventional equipment.
Safety and Reliability: Designed for flammable and explosive conditions in oilfield operations, the system is equipped with BT4-rated explosion-proof control cabinets and local consoles compliant with Class II explosion-proof standards, ensuring safe operation in high-risk areas.
Smart Operation & Maintenance: Full automation control and IoT monitoring modules enable remote O&M, reducing labor costs by 40% and significantly improving lifecycle economy.

The successful implementation of this project marks another breakthrough for CNCLEAR Environmental Protection in the field of fracturing water reuse in oilfields. Moving forward, we will persist in innovation to deliver more efficient, safer, and bespoke water treatment solutions to customers!
