Dimethylformamide (DMF) an organic compound widely used in the pharmaceutical, pesticide, chemical, and electronics industries. During the production and processing of chemical enterprises, DMF is often used, which leads to the generation of large volumes of DMF-containing wastewater. How to properly treat this type of wastewater has become a major concern for enterprises.
DMF wastewater contains a high concentration of organic phases. If discharged directly, it not only causes negative environmental impacts but also results in resource waste. Chemical enterprises have been seeking suitable treatment methods, as traditional approaches can no longer meet current environmental protection requirements. Through experimental studies, using the centrifugal extractor for solvent extraction has proven to deliver remarkable treatment results.
Solvent extraction is currently one of the most widely applied pretreatment methods. In this process, a suitable extractant is used to transfer the organic phase from the wastewater into the extractant, followed by separation. Through stripping and other procedures, the extractant is separated from the organic phase: the organic phase can be recovered and reused, while the extractant itself can also be recycled. After subsequent treatment stages, the wastewater can meet discharge standards. This method is simple and convenient to operate, and since extractants are inexpensive and readily available, it helps enterprises reduce overall costs, improve organic phase recovery, and meet production requirements.
During solvent extraction operations, the equipment used is the CWL-M series centrifugal extractor, developed and manufactured by Zhengzhou Tiei Extraction Technology Co., Ltd. When applied in the pretreatment of organic wastewater, the centrifugal extractor can efficiently extract and separate the organic phase, enabling organic phase recovery and ensuring that the treated wastewater meets the requirements for subsequent biochemical treatment. The centrifugal extractor is available in multiple models, allowing customers to select suitable equipment based on their specific feed system and treatment capacity needs.
