Global acidified oil production enterprises are facing dual environmental pressure from strict discharge standards and resource waste problems brought by unprocessed wastewater. During oil acidification refining, hydrolysis, degumming and acid washing procedures discharge massive high-concentration organic wastewater, marked by ultra-high COD value, abundant sulfate ions, residual grease and acidic medium. Traditional simple precipitation only removes partial suspended oil, failing to realize qualified wastewater treatment and sulfate recovery simultaneously, which leads to heavy fines, production shutdown risks and loss of recyclable sulfate resources for oil processing factories across Southeast Asia, Europe, North America and the Middle East.

Global metal smelting enterprises face unprecedented regulatory pressure to eliminate liquid effluent pollution, as traditional precipitation and membrane separation methods cannot fully handle high-salinity, heavy metal-rich Metal Smelting Wastewater.

Alumina manufacturing generates massive volumes of high-alkali, high-salinity wastewater containing residual alumina, concentrated alkali liquor, and mixed inorganic salts, posing severe environmental discharge risks and resource waste challenges for global alumina enterprises. Today, theEvaporation-Crystallization Process has become the most reliable industrial technology for sustainable wastewater treatment and resource recycling in the alumina industry. Professional Alumina Evaporation-Crystallization systems enable factories to efficiently separate, recover, and reuse valuable alkali liquor and alumina resources from wastewater, completely changing the traditional model of simple wastewater discharge and bringing dual economic and environmental benefits to alumina production lines.

With the explosive development of the new energy industry, lithium battery production, recycling and cascade utilization have generated massive volumes of complex lithium battery wastewater every year. This kind of wastewater contains high-concentration lithium salts, fluorides, heavy metals and soluble miscellaneous salts, which cannot be effectively recycled by traditional filtration and chemical precipitation technologies. The mature and industrial-verified evaporation crystallization process has become the most reliable technical route for precise lithium extraction and wastewater resource utilization, helping global new energy enterprises turn waste lithium-containing wastewater into recyclable lithium resources and achieve green and low-carbon production.

Magnesium sulfate wastewater mainly originates from chromium chemical reduction waste liquid, sulfur black dye by-products, lithium battery recycling, and magnesium desulfurization processes. It is characterized by high solubility, a significant increase in boiling point, and a tendency to scale and clog pipes. To address these characteristics, several mature evaporation crystallization processes have been developed industrially.

Discharge of desulfurization wastewater is a key step in achieving "full reuse and zero discharge" of wastewater from coal-fired power plants. The core of this process lies in converting the wastewater into reusable water and solid crystalline salts through two main steps: concentration and solidification. Currently, the mainstream processes fall into two main categories: flue gas waste heat utilization and evaporation crystallization.

Low-Temperature Concentration Preserves Quality: Operating temperature decreases progressively (75℃ for the first effect → 62℃ for the second effect → 48℃ for the third effect), effectively preserving heat-sensitive Vitamin C, flavor compounds, and nutrients. Vitamin C retention rate can reach over 90%.
