DMF wastewater treatment is to extract and recycle DMF in wastewater. DMF is N,N-dimethylformamide, an organic compound. A large amount of DMF wastewater will be produced in the chemical production process. This type of wastewater has a high organic content, a large amount of wastewater, and high COD. Biochemical treatment is very troublesome. It is necessary to carry out a pretreatment in the early stage to extract the DMF in the wastewater, reduce the COD, and then treat and discharge it.
Extraction DMF From Wastewater By Centrifugal Extractor
CWL-M series centrifugal extractor is a new, efficient and energy-saving liquid-liquid extraction and separation equipment. It can be used in the pretreatment of chemical organic wastewater to extract the organic phase from the wastewater, which can be recycled and reused. The COD of the treated wastewater is reduced to the standard that can be treated in the biochemical stage.
The CWL-M series centrifugal extractor is a new type of extraction equipment independently developed and produced by Zhengzhou Tiei Extraction. In addition to being used in the environmental protection industry, it can also be used in chemical pharmaceuticals, hydrometallurgy, fine chemicals, phosphorus chemicals and other fields.
Process flow of extracting DMF from wastewater by centrifugal extractor
The process of extracting DMF from wastewater uses solvent extraction. A suitable extractant is selected, and the extractant and wastewater are injected into the centrifugal extractor at a certain ratio. Through the operation of the equipment, the two-phase liquid is mixed and separated, and the DMF in the wastewater is transferred to the extractant and separated from the wastewater. Then back extraction is carried out to separate the extractant from DMF, and the extractant is recovered and recycled, and DMF can also be reused.
Performance advantages of CWL-M centrifugal extractor
- Centrifugal extractor adopts a top-suspended single-point structure, and there is no bottom bearing and mechanical seal in the processing area, so there is no risk of leakage.
- Centrifugal extractor has a large processing capacity, is more energy-efficient, has a high extraction rate, and has a good extraction effect.
- Centrifugal extractor can be made of perfluorinated polymer materials, which can resist corrosion from strong acids (hydrochloric acid, mixed acids, etc.).
- Centrifugal extractor has a high degree of automation and can adapt to intermittent and continuous operation.
The centrifugal extractor is used to extract DMF from wastewater, and the extraction effect is very good. If you also have related project needs, you can contact us.
