Known as the “King of Magnets,” NdFeB magnetic materials are widely used in industries such as new energy vehicles, wind power generation, and consumer electronics. During the manufacturing process, various types of waste materials—including machining sludge and oil-containing scrap—are generated,…

In industries such as chemical fiber production, polyimide film manufacturing, pharmaceuticals, and electronic materials, Dimethylacetamide (DMAC) is widely used as an excellent solvent due to its strong polarity and high boiling point. However, DMAC is completely miscible with water at…

In the chemical and pharmaceutical production industries, N,N-Dimethylformamide (DMF), as a “universal solvent,” is widely used in various applications. However, DMF wastewater treatment has long been a global challenge for the industry. This type of wastewater is characterized by the…

In the fields of hydrometallurgy and new energy materials, nickel sulfate is a core raw material for lithium battery cathode materials and the electroplating industry, and its purity directly determines the quality of end products. However, in industrial production, nickel…

The electroplating industry is one of the major sources of heavy metal wastewater discharge. Chromium-containing wastewater, especially wastewater containing hexavalent chromium (Cr⁶⁺), is highly toxic and hazardous, and is classified as a key regulated toxic pollutant. Most electroplating enterprises discharge…

Zinc sulfate, as an important inorganic chemical raw material, is widely used in electroplating, agriculture, pharmaceuticals, new energy materials, and many other industries, with continuously growing market demand. Currently, zinc sulfate production mainly relies on hydrometallurgical processes, extracting and purifying…
