Myande signed a contract to supply one 8TPH sodium sulfate MVR evaporation and freezing crystallization system to Xindaxin Chemical Materials Co., Ltd. This facility will represent China’s first wastewater treatment project by means of combination between evaporation and freezing crystallization process in rubber auxiliary industry. When completed, this facility will enable Xindaxin Company to realize the goal of zero discharge of wastewater in a real sense, to achieve resource recycling, to enhance enterprise development, to improve the ecological environment, and to reap both economic and social benefits.
Xindaxin Chemical Materials Co., Ltd, founded in 1990, is located in Beijing-Tianjin-Hebei High-tech Industrial Zone. It is a comprehensive enterprise that produces rubber accelerator, phenolic board, thermal insulation material and other products. It’s a designated enterprise of the Ministry of Chemical Industry with an annual turnover of over RMB100 million. With advanced management mode and intelligent information management, the enterprise has been continuously developed and expanded, and has successively been awarded the titles of first-level measurement unit, second-level archives management enterprise, integrity compliance unit, clean and civilized factory and city-level advanced enterprise.Now it also has passed the certification of ISO 9001 international standard quality system.High-quality products guaranteed by scientific management and advanced process are sold well all over the country and exported to Europe, America, Asia and other countries.
The Sodium Sulfate to be supplied by Myande will adopt "evaporation-freezing-re-evaporation" process design, combining the energy-saving technology of MVR. Sodium sulfate in wastewater is separated by crystallization to obtain sodium sulfate anhydrous, and the condensate produced by evaporation is recovered and used continuously. The adoption of this system not only solves the environmental protection problem of wastewater treatment, but also greatly reduces the production energy consumption of the whole plant.
