Success Story: Turning Wastewater into High-Purity DMF
One chemical plant successfully upgraded its wastewater treatment process by adopting Tiei Extraction’s CWL-M centrifugal extractor. The wastewater, initially containing 16% DMF, was processed at room temperature with a daily capacity of 15 tons. After just 2–3 stages of extraction, the DMF purity soared to 99.5%+, while the water content dropped to below 0.05%. The recovered DMF not only meets but exceeds reuse standards, enabling the plant to achieve both cost savings and sustainable resource recovery.
Why Solvent Extraction? A Smarter Alternative to Conventional Biochemical / SBR Processes
1.Up to 300% Higher Treatment Efficiency – Achieve results in a fraction of the time
2.60% Lower Operating Costs – Significant savings on energy and consumables
3.70% Smaller Footprint – Compact design, ideal for space-limited facilitie
Three Key Advantages of CWL-M Centrifugal Extractor
The CWL-M centrifugal extractor is a new-generation, fast, and high-speed liquid–liquid extraction and separation equipment, fundamentally different from traditional equipment such as mixer settler and extraction column. The centrifugal extractor uses a motor to drive the drum to rotate at high speed. Two liquids with different densities and immiscible with each other are mixed and mass transfer under the shear force generated by the rotation of the drum or blades, and are quickly separated under the centrifugal force generated by the high-speed rotation of the drum.
1.Energy consumption is only 1/10 of traditional equipment – saving over 200,000 kWh annually.
2.Fully automated operation – requires only one operator.
3.Proprietary centrifugal technology – achieving 99.8% separation efficiency.
DMF Wastewater Treatment Process
1.Extraction Stage: 2–3 stages of precision extraction with the CWL-M centrifugal extractor unit.
2.Stripping Stage: extract agent recycled with zero waste.
3.Resource Recovery: DMF purity >99.5%, directly reusable.
The CWL-M series centrifugal extractor stands out with their exceptional efficiency and superior performance.
