Japan is globally recognized for its stringent environmental regulations, particularly the Water Pollution Control Law, which mandates rigorous standards for industrial effluent. As Japanese industries—from the automotive giants in Aichi to the semiconductor hubs in Kyushu—transition toward Society 5.0 and carbon neutrality by 2050, the demand for high-efficiency Wastewater Evaporator Systems has reached an all-time high.
Manufacturers in Japan are increasingly moving away from traditional biological treatment toward Zero Liquid Discharge (ZLD) technologies. This shift is driven by the need to recover high-value resources from wastewater and reduce the environmental footprint of heavy manufacturing. Our systems are specifically engineered to meet these high Japanese engineering standards, offering reliability, energy efficiency, and compact footprints suitable for space-constrained Japanese factories.
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. The company covers an area of over 54,000 square meters, with a production workshop area of over 22,000 square meters.
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.
Treatment of high-salinity wastewater from wafer fabrication in Kumamoto and Tohoku regions, focusing on water reclamation.
Efficient concentration of fermentation by-products and alcoholic wastewater in traditional and modern breweries across Kyoto and Niigata.
Handling complex organic wastewater and solvent recovery for pharmaceutical clusters in Toyama and Osaka.
The Japanese market is a pioneer in adopting Mechanical Vapor Recompression (MVR) technology. Unlike traditional multi-effect evaporators that rely heavily on fresh steam, MVR systems utilize a centrifugal compressor to recompress secondary vapor, significantly reducing energy consumption. This aligns perfectly with Japan's "Green Growth Strategy," which incentivizes factories to lower their CO2 emissions.
Our MVR and TVR (Thermal Vapor Recompression) systems are designed with AI-driven control modules. These systems allow for remote monitoring and predictive maintenance, a feature highly valued by Japanese plant managers who prioritize automation and "kaizen" (continuous improvement). By integrating IoT sensors, our evaporators can adjust to fluctuating wastewater compositions in real-time, ensuring stable discharge quality even in complex industrial environments.
In March 2002, the company took the lead in obtaining ISO9001:2015 international quality system certification. In July 2007, it became a Jiangsu Provincial High-Tech Enterprise. In April 2009, we obtained the Special Equipment Manufacturing License. In August 2012, we acquired the ASME "U" Stamp authorization, marking our entry into global high-end manufacturing.







We hold a leading position in evaporation technology and cooperate with renowned groups including Yihai Kerry, Meihua Group, and North China Pharmaceutical Group.









As Japan continues to lead in environmental preservation, the role of Wastewater Evaporator System Manufacturers becomes pivotal. Our factory provides not just equipment, but comprehensive solutions for liquid concentration, including distillates, ammonium sulfate, itaconic acid, threonine, sorbitol, glucose, and high-salinity organic wastewater. By reducing steam consumption and maximizing heat recovery, we help Japanese enterprises achieve their ESG (Environmental, Social, and Governance) goals.
While meeting domestic market demand, our alcohol equipment and dryer series have been exported to Russia and Southeast Asian markets. We are capable of providing professional technical support and after-sales service nationwide. We warmly welcome friends from Japan and all over the world to visit us for cooperation and mutual development!
