Explore our CE-certified, energy-efficient thermal processing solutions engineered for high performance, material recovery, and compliance.
The global shift toward high-performance concentration, Zero Liquid Discharge (ZLD), and energy integration.
Over the past three decades, the engineering landscape of industrial wastewater treatment has shifted from high-utility Multiple Effect Evaporators (MEE) to highly optimized Mechanical Vapor Recompression (MVR) systems. This transition is heavily driven by global energy prices, decarbonization goals, and strict municipal wastewater codes.
Traditional systems require massive steam consumption to drive successive boiling chambers. MVR systems, by contrast, compress the secondary vapor generated during the boiling process using a high-efficiency centrifugal blower or turbo-compressor. This raises both the pressure and thermal state of the vapor, allowing it to act as the heating medium for the same boiling chamber. The latent heat of vaporization is fully reused, reducing fresh steam consumption down to near zero during steady-state runs.
This thermal loop achieves energy consumption figures as low as 15 to 25 kWh per ton of evaporated water, which is up to 90% more efficient than single-effect thermal options.
Analyzing our core thermal and drying technologies designed for high moisture loads and heat-sensitive concentrations.
Jiangsu Zongheng's MQG Airflow Dryer employs high-speed hot air to suspend and fluidize materials. By utilizing impulse airflow generated from precisely varied tube diameters, it continuously tumbles particles while conveying them. This design ensures rapid, uniform, and efficient drying throughout the entire transportation process within the system.
A falling film evaporator efficiently concentrates heat-sensitive liquids. The feed liquid forms a thin film flowing down heated vertical tubes, where it partially evaporates. Vapor generated flows parallel to the liquid, enhancing the process. It ensures a short residence time and low operating temperature, preserving product quality. The system requires proper liquid distribution and complete surface wetting to prevent fouling and maintain high thermal efficiency and operational stability.
Specially developed by Zongheng for high-viscosity, fouling-prone, or crystal-forming wastewater streams. An integrated axial flow circulation pump keeps the process fluid moving at high velocities within the heat exchanger tubes. This design suppresses boiling at the tube surfaces, preventing crusting and optimizing heat transfer rates under heavy solids loading.
Meeting the technical, mechanical, and safety compliance expectations of global enterprises.
For multinational corporations and EPC contractors, choosing industrial wastewater evaporators goes beyond simple capacity numbers. Key considerations include chemical composition compatibility, continuous operational durability, and safety certifications.
Corrosion Mitigation: Wastewater streams from chemical plants, lithium-ion battery production, or desulfurization scrubbers contain high concentrations of chlorides and organic acids. We offer custom alloy fabrications, including Duplex Stainless Steel (2205, 2507), Titanium (Gr. 2, Gr. 12), and Hastelloy (C276, C22), ensuring the system survives harsh acidic environments without pitting.
Manufacturing Standards: Our engineering processes align with international quality standards. We hold the ASME "U" Stamp authorization, ensuring pressure vessel compliance across the Americas, and CE Certification for European installations. Every evaporator undergoes thorough radiographic inspection, pressure testing, and performance validation before shipping.

The future of intelligent vacuum evaporators and energy recovery optimization.
Our upcoming system designs integrate advanced sensor grids that monitor temperature differences, boiling pressure, and vapor velocity in real time. Automated PLC feedback loops adjust compressor speeds to maintain peak thermal efficiency during feed fluctuations.
By optimizing the mechanical polishing of vertical tubes and introducing low-fouling dynamic films, we continue to improve global heat transfer coefficients (U-values). This reduction in surface fouling helps prolong system runtimes between Clean-In-Place (CIP) cycles.
Our engineering team focuses on circular solutions, helping factories recover valuable raw minerals, proteins, and chemical concentrates from wastewater streams while returning clean water back to the utility loop.

The evaporator absorbs heat to vaporize media, while the condenser releases heat to liquefy vapor; the two perform opposite cooling and heating functions. Operating under low pressure, the evaporator generates cold energy and concentrates process fluids, ensuring efficient separation while protecting valuable residues.
