The global shift toward "Circular Economy" models is driving metal finishers to not only treat wastewater but to recover resources. Modern Multi-Effect Evaporators are now being integrated with ion exchange and membrane systems to create closed-loop water cycles. This trend is accelerated by the rising costs of raw materials and the stringent environmental regulations in regions like China, Europe, and North America.
MEE systems can concentrate chromic acid rinse water back to plating-bath strength, allowing for direct reuse. This eliminates the need for expensive reduction and precipitation of Hexavalent Chromium.
In high-value plating lines (Gold, Silver, Nickel), MEE technology enables the recovery of metal salts from the rinse water, providing a direct Return on Investment (ROI) through material salvage.
For facilities with complex, mixed effluent streams, Multi-Effect Evaporators act as the final concentration step before a crystallizer, ensuring that only solid salt cakes remain for disposal.
Jiangsu Zongheng Concentration & Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory), founded in 1992, is located in Zhoutie Town, Yixing City, on the shores of the beautiful Taihu Lake.
Jiangsu Zongheng is a modern high-tech enterprise specializing in the manufacturing of concentration, drying, starch industry, alcohol DDGS, and Category III medium & low-pressure vessel equipment. It is currently a member enterprise of the China Starch and Alcohol Association. Its products are widely used in industries such as food fermentation, alcohol, chemical, pharmaceutical, environmental protection, and petrochemical.
In a single-effect evaporator, 1 ton of steam evaporates roughly 1 ton of water. In a triple-effect system, that same 1 ton of steam can evaporate nearly 2.5 to 2.8 tons of water. For a metal finishing plant processing 50m³ of rinse water daily, this translates to hundreds of thousands of dollars in energy savings annually.
Establishing a complete quality assurance system aligned with international standards including ISO9001:2015, ASME "U" Stamp, and Special Equipment Manufacturing Licenses.
Jiangsu Zongheng is always committed to exploration and innovation. Main products include evaporation plants, comprising Multi-Effect Evaporators, Thermal Vapor Recompressors (TVR), Waste Heat Evaporators, and Mechanical Vapor Recompressors (MVR). These are widely used for liquid concentration, including distillates, alcohol stillage, ammonium sulfate, corn steep liquor, itaconic acid, threonine, starch sugar, sorbitol, glucose, fructose, trehalose, erythritol, organic wastewater, high-salinity wastewater, etc.
The company's other main products include Tube Bundle Dryers (up to 1600m²), Single Screw Fiber & Germ Dehydrators, and Wash Cyclones, recognized as high-quality products by industry leaders.
The company currently holds a leading position in evaporation technology and has extensive cooperation with many renowned large domestic group companies.
While meeting domestic market demand, our DDGS alcohol equipment and tube bundle dryer series products have been exported to Russia and Southeast Asian markets. We are capable of providing professional technical support and after-sales service nationwide for our vast user base.
We warmly welcome friends from various industries, both domestic and international, to visit us for cooperation and mutual development!
