The YQF-30 wastewater pretreatment skid is primarily used for the pretreatment of oily wastewater, reducing the content of suspended solids and oil in the water. It also realizes the function of scum drying.

The equipment integrates the air compressor, three-phase mixer, air flotation system, high-speed centrifuge, dosing system, and control system, all mounted on a skid. It can be used in series with fine filtration devices.

1.Integrated Skid-Mounted Design: Featuring a unique appearance, compact internal structure, excellent mobility, and safe, reliable operation, it facilitates on-site management.

2.Simplified Traditional Processing: The traditional process flow is simplified, enhancing the water purification effect.

3.Application of Three-Phase Mixing Technology: Based on vortex dissolved air and vortex mixing technology, it improves the effectiveness of both the container and the mixing process.

4.Fully Automated Process Control: With a visual interface for operation, the system offers reliable performance, self-diagnosis of faults, and the ability to operate unattended.
