8 тонн фтора – высокая концентрация – план обработки соляного маточного раствора

With the growing global demand for crop protection and medical health, the pesticide and pharmaceutical industries have developed rapidly. One of the core links of these industries is the production of pesticide and pharmaceutical intermediates, which is not only crucial to the quality and efficiency of the final product, but also brings significant environmental challenges. During the production process, a large amount of wastewater is discharged, which contains a variety of toxic and harmful substances, such as organic matter, heavy metals, nitrogen and phosphorus compounds, etc., causing serious pollution to the water body. Therefore, the development and implementation of effective comprehensive wastewater treatment strategies have become the key to achieving sustainable development of the industry. Next, through the case of fluorine-containing high-salt mother liquor wastewater treatment of a large fine chemical enterprise in my country, the process of high-salt mother liquor wastewater treatment of fine chemical enterprises will be explained.

Details and difficulties of wastewater treatment of a fine chemical customer in Shandong

The customer is a leading fluorine chemical enterprise in Shandong. There are about 8 tons of trifluoroethanol high-salt mother liquor every day. The wastewater mainly contains hydroxyacetate ions and a large number of corrosive fluoride ions, chloride ions and other pollutants, with acetate ions 10%-12%, hydroxyacetate ions 5%-10%, and fluoride ion content 3%-7%. The customer originally outsourced the disposal, which was costly, about 2,000 yuan/ton.

Winsonda helps customers achieve concentration and reduction of high-salt mother liquor

In response to customers’ wastewater reduction needs, at the beginning of 2024, Winsonda Environmental Protection, after small-scale testing, pilot verification and discussion of specific design plans, finally customized a set of fine chemical high-salt mother liquor low-temperature evaporation crystallization solutions and process equipment for customers. The daily processing capacity of the device is 8 tons of wastewater. Since its operation, the treatment effect of the device has remained stable. Crystallized salt is outsourced for disposal, and potassium acetate solution is prepared with recycled water.

The efficient operation of Winsonda’s low-temperature evaporation crystallization device has created three major values for customers:

(1)It truly solves the demand for reducing mother liquor with guaranteed quality and quantity;

(2)It reduces the amount of hazardous waste outsourced for disposal and the cost of disposal. The outsourced processing volume has been reduced by about 60%, which has improved the company’s economic benefits and market competitiveness;

(3)It has efficient, stable and automated operation, which reduces the need for labor and ensures the stability of the entire wastewater treatment system.

The Winsonda low-temperature evaporator has been in operation so far and has been highly recognized by customers. In the future, we will continue to purchase more Winsonda devices for application in the production process.
