Breaking the Space Bottleneck: CDFU Cyclonic DAF for Oilfield Reinjection Water

In the middle and late stages of oilfield development, as the water cut keeps rising, produced-water treatment and reinjection have become the core link for stable production and environmental compliance. Yet whether on space-tight offshore platforms or in decades-old onshore fields, operators face a severe shared challenge: a serious shortage of treatment space.

Traditional large settling tanks and lengthy flotation basins occupy huge areas and require complex civil works, making them hard and slow to deploy where space is limited. How can highly efficient, compact equipment be rapidly deployed while steadily meeting strict reinjection standards? The CDFU (Cyclonic Dissolved-Air Flotation) unit independently developed by SINOKLE is the ideal answer engineered for exactly this industry-wide bottleneck.

Skid-Mounted and Modular: Beating the Space Constraint

The CDFU unit creatively integrates cyclonic centrifugal separation, micro-bubble generation, and dissolved-air flotation into a single device, using standardized, skid-mounted, and modular design that fits every space-sensitive project.

Extremely Compact — Only 10%–30% of the Footprint of Conventional DAF

Through CFD flow-field optimization, the CDFU achieves high separation efficiency within a tiny footprint. Its compact, modular skid can be installed offshore or retrofitted into existing stations without the heavy civil engineering that conventional basins demand, dramatically shortening project schedules.

By replacing sprawling gravity separation with cyclonic and dissolved-air flotation, the CDFU delivers stable, compliant reinjection water even at crowded well sites, turning a once-unsolvable space problem into a deployable, efficient solution.
