Engineered for American industrial standards — our waste heat evaporators deliver maximum efficiency, regulatory compliance, and proven performance across food processing, ethanol, chemical, and environmental sectors.
The U.S. industrial wastewater treatment market is one of the largest and most regulated in the world. Stringent EPA standards, rising energy costs, and growing Zero Liquid Discharge (ZLD) mandates are driving unprecedented demand for advanced effluent evaporation technology across multiple sectors.
The Midwest's massive corn wet-milling and ethanol production corridor — spanning Iowa, Illinois, Indiana, and Nebraska — generates enormous volumes of corn steep liquor and stillage that require efficient evaporation and concentration solutions.
U.S. chemical and pharmaceutical manufacturers face increasingly strict EPA effluent discharge limits. Waste heat evaporators provide a cost-effective path to compliance while recovering valuable by-products and reducing disposal costs.
From dairy operations in Wisconsin to sugar processing in Louisiana, food manufacturers across the U.S. rely on evaporation technology to concentrate products, treat process wastewater, and meet stringent environmental discharge standards.
Power plants and oil refineries in Texas, Pennsylvania, and the Gulf Coast generate high-salinity wastewater and flue gas desulfurization effluent that require robust evaporation systems to achieve zero liquid discharge compliance.
The booming U.S. biotechnology and fermentation industry — producing amino acids, organic acids, and specialty chemicals — requires precise evaporation and concentration systems for products like threonine, itaconic acid, and erythritol.
As water scarcity concerns grow across the American Southwest and Southeast, municipalities and environmental engineering firms are increasingly adopting advanced evaporation technology for landfill leachate and industrial effluent treatment.
Several powerful regulatory, economic, and technological forces are reshaping the American effluent evaporation landscape — creating significant opportunities for energy-efficient, high-performance solutions.
The EPA's increasingly strict effluent limitation guidelines are pushing industrial facilities across the U.S. toward Zero Liquid Discharge systems. Waste heat evaporators are a critical component of ZLD solutions, enabling facilities to eliminate wastewater discharge entirely while recovering valuable salts and minerals.
With U.S. energy costs rising and corporate sustainability commitments intensifying, waste heat evaporation technology — which captures and reuses thermal energy that would otherwise be wasted — is becoming a cornerstone of industrial energy efficiency programs across sectors.
American industrial operators are demanding evaporation systems with advanced automation, real-time monitoring, and predictive maintenance capabilities. Modern waste heat evaporators now integrate seamlessly with SCADA systems and Industry 4.0 platforms for optimized performance and remote diagnostics.
Publicly traded U.S. companies face growing ESG reporting requirements and investor pressure to reduce carbon footprints. Waste heat evaporators directly reduce steam consumption and greenhouse gas emissions, making them a strategic investment for companies pursuing science-based carbon reduction targets.
The U.S. manufacturing renaissance — driven by the CHIPS Act, IRA incentives, and supply chain reshoring — is creating a wave of new industrial facilities that require state-of-the-art wastewater treatment infrastructure, including high-capacity effluent evaporation systems.
Drought conditions across the American West and increasing water costs nationwide are accelerating adoption of water recovery technologies. Effluent evaporators enable facilities to recover and reuse process water, dramatically reducing freshwater consumption and municipal discharge fees.
Our waste heat evaporation systems are engineered for the full spectrum of American industrial applications — delivering reliable, energy-efficient performance across diverse process streams.

Jiangsu Zongheng Concentration & Drying Equipment Co., Ltd.
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.
The company's other main products include Tube Bundle Dryers, with design and manufacturing capabilities reaching 1600m² (making it a primary manufacturer of large tube bundle dryers). Other main products such as Single Screw Fiber & Germ Dehydrators and Wash Cyclones are recognized as high-quality products by starch manufacturers and the industry. High-quality products and a sincere service attitude have won consistent praise and trust from numerous users at home and abroad, fully demonstrating the company's first-class technical advantages and manufacturing capabilities for large-scale equipment.
Jiangsu Zongheng is always committed to exploration and innovation. Through years of sincere effort and user support, it has achieved sustained development. Main products include evaporation plants, comprising Multi-Effect Evaporators, Thermal Vapor Recompressors (TVR), Waste Heat Evaporators, and Mechanical Vapor Recompressors (MVR, achieving minimal unit energy consumption). 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., making the company one of the domestic manufacturers with the most extensive product variety.
In March 2002, the company took the lead in obtaining ISO9001:2015 international quality system certification (Certificate No.: 45021), establishing a complete quality assurance system aligned with international standards. In July 2007, it became a Jiangsu Provincial High-Tech Enterprise. In April 2009, the company obtained the Special Equipment Manufacturing License of the People's Republic of China (License No.: TS2232C42). In August 2012, it acquired the ASME "U" Stamp authorization — a critical qualification recognized by U.S. industry — marking the company's entry into a new phase of international development. The company possesses strong R&D capabilities and advanced manufacturing processes, currently employing over 3 senior engineers and more than 20 engineers and assistant engineers. Multiple innovative technologies have been patented, and many products hold leading positions domestically.
The company currently holds an absolutely leading position in evaporation technology and has extensive cooperation with many renowned large domestic group companies, including Zhuofeng Biology, Meihua Group, Yufeng Group, Yihai Kerry, North China Pharmaceutical Group, Harbin Pharmaceutical Group, Shouguang Juneng, Qilu Pharmaceutical, Qiyuan Pharmaceutical, Xiwang Group, Shengtai Biology, Zhejiang Huakang, Kelun Pharmaceutical (Yili), and Shandong Tianli.
