Explore our premium selection of CE-certified waste heat and energy-saving wastewater evaporator systems, optimized for the high-efficiency demands of industrial zones in Ho Chi Minh City and neighboring provinces.
As the economic engine of Vietnam, Ho Chi Minh City (HCMC) and its surrounding metropolitan areas—including Binh Duong, Dong Nai, and Long An—are experiencing an unprecedented industrial expansion. Home to massive industrial hubs like the Tan Thuan Export Processing Zone, Hiep Phuoc Industrial Park, and Saigon Hi-Tech Park, the region is a global magnet for manufacturing, food processing, electronics, and chemical production.
However, this rapid growth has brought significant environmental responsibilities. The Vietnamese government, through the Ministry of Natural Resources and Environment (MONRE), has continuously tightened regulations on industrial effluent. Under the Environmental Protection Law 2020, factories are mandated to implement strict wastewater treatment technologies, moving towards Zero Liquid Discharge (ZLD) to protect critical waterways like the Saigon River and Dong Nai River.
For local factories, traditional treatment methods are no longer sufficient to handle complex, highly concentrated, or high-salinity industrial wastewater. This is where CE-certified Wastewater Evaporator Systems become indispensable, offering a reliable pathway to separate clean water from concentrated contaminants, enabling recycling and absolute compliance.
With over 17 operational industrial parks and export processing zones in HCMC alone, the daily discharge of industrial effluent exceeds hundreds of thousands of cubic meters. The demand for energy-efficient evaporation plants (MVR and TVR) has grown by over 25% annually as factories seek to reduce environmental taxes and reuse process water.
Different industries require customized evaporation profiles. Jiangsu Zongheng design and manufactures tailored systems matching the specific raw wastewater profile of local HCMC factories:
Southern Vietnam is a powerhouse for agricultural and seafood exports. Evaporators are widely used to concentrate corn steep liquor (CSL), starch sugar, glucose, fructose, and seafood processing effluents. By recovering valuable by-products, factories turn wastewater treatment into a profit center.
HCMC's chemical zones generate highly toxic, high-salinity wastewater containing ammonium sulfate and organic solvents. MVR and multi-effect evaporators effectively crystallize salts and reclaim high-purity water, fulfilling the strict environmental standards of modern industrial parks.
Textile mills in Binh Duong and Long An consume vast amounts of water and discharge heavily colored, saline effluents. Our waste heat and MVR evaporators process reverse osmosis concentrates and distiller's dried grains with solubles (DDGS) in alcohol plants, achieving Zero Liquid Discharge.
With rising electricity and fuel tariffs in Vietnam, the industrial sector is transitioning away from high-consumption, traditional thermal treatment systems. The market demand is heavily shifting towards low-utility, high-efficiency system configurations:
MVR systems utilize a centrifugal compressor to recompress secondary vapor, upgrading its temperature and pressure to be reused as the heating source. This eliminates the need for fresh steam during normal operation, cutting operating costs by up to 60-80% compared to traditional single-effect evaporators.
For plants where steam is readily available, TVR systems utilize steam ejectors to entrain and compress a portion of the secondary vapor, improving thermal efficiency and reducing overall steam consumption.
Many factories in HCMC run boilers, dryers, or power generators that release substantial waste heat. Our waste heat evaporators integrate these secondary energy streams into the concentration process, transforming thermal waste into a functional driver for wastewater purification.
CE certification guarantees compliance with European health, safety, and environmental protection standards. For multinational brands operating in HCMC, CE-certified machinery ensures seamless safety audits, insurance approvals, and stable factory operations.

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 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, marking the company's entry into a new phase of 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'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.
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.
