How should wastewater containing 10%–20% DMF, along with small amounts of dichloroethane and toluene, be treated? How is DMF recycled?
DMF is recovered through distillation, and the wastewater can meet the discharge standards. Private messaging is available; detailed information on the materials can be provided, along with technical support

Hello, could we discuss the recycling of DMF?
First, dichloroethane and toluene are removed, then water is removed, and finally the DMF of satisfactory quality is obtained through purification

A wastewater evaporation system needs to be added
All are expert-level. I’m sorry for being verbose.
