In the field of advanced metallurgy and strategic resource recovery, the extraction and purification of critical metals such as niobium, tantalum, and cesium are directly tied to the development of key industries including aerospace, new energy, and electronic communications. However,…

In the production processes of the petrochemical, vegetable oil refining, and pharmaceutical synthesis industries, large volumes of industrial wastewater containing naphthenic acid are generated. This type of wastewater is complex in composition, features high COD levels, and is severely emulsified.…

In high-end manufacturing fields such as fine chemicals, pharmaceuticals, agrochemicals, and new materials, product purity directly determines its value and market competitiveness. Inorganic salts, residual catalysts, and acidic or alkaline impurities remaining in the reaction system are like “grains of…

In today’s rapidly growing printed circuit board (PCB) industry, the etching process, as the core production stages, generates large volumes of waste etching solution rich in copper ions. If discharged directly, these waste liquids not only lead to a significant…

During pesticide production, the discharged wastewater often contains high concentrations of phthalic acid and other benzene derivatives. This type of wastewater is complex in composition, highly toxic, and poorly biodegradable. Traditional treatment methods are costly and make resource recovery difficult.…

In the production and research of fine chemicals, pharmaceuticals, and environmental protection industries, efficient separation is a key factor determining product quality and process success. Addressing the shortcomings of traditional sedimentation and static stratification methods, such as low efficiency, incomplete…
