Engineered for compliance, resource recovery, and significant operational cost reductions.
As global environmental mandates tighten and zero liquid discharge (ZLD) shifts from a corporate social responsibility initiative to a hard regulatory requirement, the demand for high-performance, robust, and certified industrial evaporation equipment has surged. In this context, CE Certified Wastewater Evaporator Systems stand at the intersection of regulatory compliance and mechanical engineering excellence.
European CE marking guarantees that pressure vessels, electrical instrumentation, and thermal separation blocks meet mandatory European health, safety, and environmental protection standards. For global procurement officers, consulting engineers, and plant operators, importing equipment with certified CE markings mitigates regulatory risks, ensures operational safety, and facilitates smooth local authority approvals.
Transitioning from multi-effect steam-dependent systems to Mechanical Vapor Recompression (MVR) reduces energy usage up to 90%.
Detailed verification of CE Certificates, ASME U-stamp alignment, and ISO 9001:2015 manufacturing workflows.
Strategic deployment of duplex stainless steel (2205/2507) and titanium to counteract aggressive halides in wastewater streams.
Innovations in energy recovery and digital process controls reshaping industrial water management.
MVR operates on the principle of recycling latent heat from secondary vapor. By compressing the vapor mechanically, its temperature and pressure increase, allowing it to be reused as the heating source for the same evaporation stage. This results in minimal external steam requirements, drastically lowering carbon footprints.
Ideal for low-viscosity, heat-sensitive industrial streams. The wastewater descends inside vertical tubes as a uniform thin film. High heat transfer coefficients coupled with short residence times reduce structural fouling and scale formation, preserving thermal efficiency across prolonged continuous campaigns.
Designed specifically to process high-TDS (Total Dissolved Solids) and highly fouling wastewater concentrates. High-speed axial pumps force fluid through heat exchangers at velocities that prevent crystallization on tube walls. Precipitation occurs only inside the separator vessel, protecting vital system elements.
Explore our foundational equipment systems engineered for concentration, dewatering, drying, and refinement.
We deliver custom-engineered, multi-effect, and MVR evaporation systems designed to concentrate industrial wastewater, recovery process solvents, and execute ZLD goals. Our portfolio includes:
Specifically engineered for dewatering solid-containing industrial slurries, agricultural residues, and fibrous materials before thermal drying processes.
By applying continuous mechanical pressure through a variable-pitch screw shaft, it separates free liquids from solids. This step reduces the overall moisture content, directly cutting the thermal energy load required in downstream drying units.
Jiangsu Zongheng's ZXG Tube Bundle Dryer offers safe, indirect steam-based drying. It is highly suited for loose materials with high moisture levels, such as corn gluten, DDGS, starch byproducts, and chemical powders.
The system features a rotating steam-heated tube bundle wrapped inside a stationary shell. Heated tubes continuously lift and tumble materials, ensuring safe, uniform low-oxygen drying while maintaining a stable, controllable environment.
Jiangsu Zongheng's MQG Airflow Dryer employs high-speed hot air to suspend and fluidize the material. By utilizing impulse airflow generated from precisely varied tube diameters, it continuously tumbles the particles while conveying them.
This aerodynamic engineering ensures rapid, uniform, and efficient drying throughout the entire transportation process within the system, making it ideal for processing starch, proteins, and chemical crystals.
Our ancillary refining equipment optimizes starch wet-milling processes, ensuring high recovery yields and purity:
Procuring heavy-duty industrial machinery from international suppliers requires careful evaluation of safety, structural integrity, and manufacturing compliance. Industrial wastewater treatment plants work under pressure and handle corrosive materials, making compliance non-negotiable.

How Jiangsu Zongheng leverages automated workflows, localized supply clusters, and engineering expertise to deliver global value.
Located in Yixing City (Zhoutie Town), Jiangsu Zongheng operates at the heart of one of the world's most advanced chemical machinery manufacturing clusters. This proximity ensures immediate access to verified steel suppliers, specialized surface treatment providers, and professional logistics. This clustering lowers lead times and controls structural material costs.
Wastewater systems must withstand high thermal expansion and chemical corrosion. Our 22,000+ square meter facility uses automated longitudinal and circumferential seam welding machines, CNC plasma cutters, and dedicated tube sheet orbital welding systems. Every weld undergoes rigorous non-destructive testing (NDT), including radiographic and ultrasonic tests, matching ASME and CE requirements.
With more than three decades of experience, Zongheng's team includes three senior engineers and over twenty engineering specialists. We use advanced thermal calculations and finite element analysis (FEA) to simulate pressure distribution, thermal stresses, and fluid flows, ensuring structural safety and optimal heat transfer.
Optimizing evaporator configurations for different industrial wastewater and process streams.
Refining and washing starch generates significant wastewater streams loaded with organics. By pairing our YDX Starch Washing Cyclone with multi-effect falling film evaporators, starch factories can recycle process water, recover dissolved proteins, and concentrate high-COD wash water for drying into saleable feed co-products.
Chemical processing and refining produce aggressive, high-salinity wastewater streams that cannot be discharged. Forced circulation crystallization plants concentrate these streams to precipitate salts (e.g., Sodium Chloride, Sodium Sulfate) for landfilling or commercial reuse, achieving complete ZLD.
Distilleries utilize our concentration systems and ZXG Tube Bundle Dryers to process thin stillage into Distillers Dried Grains with Solubles (DDGS). Evaporator systems concentrate the thin stillage into a syrup that is blended back with the wet cake before final drying, turning waste into high-protein animal feed.
Tracing our growth from a local machinery factory in 1992 to a global certified technology supplier.

CE Certification ensures the wastewater evaporator complies with European directives, including the Pressure Equipment Directive (PED 2014/68/EU), the Machinery Directive (2006/42/EC), and the Low Voltage Directive (2014/35/EU). This certifies the pressure vessels, electrical panels, and safety sensors meet rigorous health, safety, and environmental protection standards.
MVR systems mechanically compress secondary vapor, increasing its heat energy to reuse it within the evaporator. This reduces external steam demand by up to 90%. While MVR systems require higher initial capital investment (CAPEX), they significantly reduce operating costs (OPEX), typically achieving return on investment (ROI) within 1.5 to 3 years.
We perform detailed water analysis before engineering the system. For acidic or chloride-rich wastewater, we build heat exchangers and contact components from specialized materials such as duplex stainless steel (S32205/S32750), titanium (Gr. 2), or high-nickel alloys. These materials resist pitting and stress corrosion cracking.
Yes. In ZLD installations, our evaporators concentrate liquid slurries into thick syrups. This syrup can be blended with solid residues and fed into the ZXG Tube Bundle Dryer. This integrated setup achieves a dry solids output suitable for recycling or disposal, utilizing thermal energy efficiently.
A falling film evaporator distributes liquid to flow down heated tubes as a thin film. This design enables high heat transfer rates with short residence times, making it ideal for concentrating mildly fouling, heat-sensitive wastewater streams before final crystallization or spray drying.
