Sodium sulfate wastewater treatment is a type of chemical high-concentration organic wastewater that many companies will produce during the production and processing process. The organic content in this type of wastewater varies. It is necessary to extract the organic components in the wastewater, and then the treated wastewater is biochemically treated and discharged.
Generally, there are several ways to treat the sodium sulfate wastewater. With the development of science and technology, the treatment methods are also constantly being optimized. Currently, the commonly used sodium sulfate wastewater treatment methods are as follows:
- Use multi-effect evaporation and crystallization treatment, which is a common method for treating sodium sulfate wastewater.
- The high-pressure flat membrane is used for concentration to 15-20%, and then MVR evaporation and multi-effect evaporation crystallization are used for treatment.
- Solvent extraction method, which is divided into two stages: extraction and stripping. This method is operated with centrifugal extractors. Solvent extraction is a common method for pretreatment of chemical organic wastewater. The process is simple to operate, has a large processing capacity, high extraction efficiency, and low comprehensive cost. Most companies currently use this method.
Solvent Extraction Process
- Extraction stage: Add concentrated sulfuric acid to adjust the pH value of sodium sulfate wastewater, then add complexing extractant, let it mix and contact with sodium sulfate wastewater, and use the different distribution ratios of pollutants in water and solvent to separate and extract pollutants.
- Stripping: Add stripping agent to strip the loaded extractant and reuse it.
CWL-M Centrifugal Extractor
The solvent extraction method uses the centrifugal extractor. The CWL-M centrifugal extractor is developed and produced by Zhengzhou Tiei Extraction. It is a new, efficient and energy saving liquid liquid extraction and separation equipment. Through a large number of cases, centrifugal extractors have been widely used in many chemical high-concentration organic wastewater treatment companies.
- The extraction effect is better.
- The cost of use is lower.
- The operation results are more stable.
- The structure of the equipment is simpler.
The centrifugal extractor is environmentally friendly and pollution-free in treating sodium sulfate wastewater, and has a large processing capacity. Welcome to contact us for details.
