Portugal, a nation with a rich industrial heritage and a modern commitment to sustainability, is currently undergoing a significant transformation in its approach to environmental management. As a leading Wastewater Vacuum Evaporators Manufacturer & Supplier, we recognize the unique challenges faced by the Portuguese market—from the historic wine regions of the Douro Valley to the high-tech industrial hubs in Sines and Setúbal. The demand for efficient, cost-effective, and environmentally friendly wastewater solutions has never been higher.
In the face of increasing water scarcity in the southern regions and stringent EU environmental directives, Portuguese industries are pivoting towards Zero Liquid Discharge (ZLD) strategies. Vacuum evaporation technology stands at the forefront of this shift, offering a way to recover clean water from complex industrial effluents while concentrating waste for easier disposal or resource recovery. Whether it is the recovery of valuable by-products in the food and beverage sector or the treatment of high-salinity brine in chemical manufacturing, our evaporators provide the technological edge needed for the modern Portuguese economy.
Enabling industries in the Algarve and Alentejo to recycle up to 98% of process water, mitigating the risks of seasonal droughts.
Meeting and exceeding the strict requirements of the European Green Deal and the Water Framework Directive (WFD).
Reducing waste disposal costs significantly by concentrating industrial sludge into a small fraction of its original volume.
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.
Our vacuum evaporation systems are engineered to handle the specific waste streams of Portugal's core industries. By understanding the local industrial landscape, we provide customized solutions that integrate seamlessly into existing production lines.
The Portuguese wine industry produces significant volumes of wastewater high in organic content (COD/BOD) and polyphenols. Our Multi-Effect Evaporators are used to concentrate vinasse and distillery slops, allowing for the recovery of tartaric acid and other valuable components while producing high-purity condensate that can be reused for cleaning processes.
As one of Europe's largest producers of eucalyptus pulp, Portugal’s paper industry requires robust systems for "Black Liquor" concentration and bleach plant effluent treatment. Our MVR (Mechanical Vapor Recompression) systems offer the lowest energy consumption per ton of evaporated water, making them ideal for the high-volume requirements of companies like Navigator and Altri.
The textile industry in northern Portugal is a global leader but faces challenges with dye-heavy wastewater. Vacuum evaporation effectively separates dyes and salts from the water, enabling a closed-loop system where water and even some chemicals can be returned to the dyeing process.
Olive Mill Wastewater (OMW) is notoriously difficult to treat due to its high antimicrobial phenolic content. Our vacuum evaporators concentrate OMW into a dense syrup that can be used for biomass energy, solving a major environmental hurdle for Portuguese olive oil producers.
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).
Our systems achieve minimal unit energy consumption and 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, and high-salinity wastewater.
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 worldwide.
The Portuguese industrial sector is currently witnessing three major trends that favor the adoption of vacuum evaporation technology:
As a global supplier, we provide not just the hardware, but the engineering expertise to help Portuguese firms navigate these transitions successfully.
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 August 2012, it acquired the ASME "U" Stamp authorization, marking our entry into the highest tier of global manufacturing standards.
We maintain leading positions in evaporation technology and cooperate with renowned large domestic and international groups, including Meihua Group, Yihai Kerry, North China Pharmaceutical Group, and many others.
