As a leading manufacturer in environmental technology since 2015, Qingdao Conqinphi Environmental Technology Group is proud to offer our expertise in designing and fabricating high-performance MVR Falling Film Evaporators. Engineered specifically for demanding Zero Liquid Discharge projects, our custom solutions are built to tackle the most challenging industrial wastewater streams, transforming waste into a resource and helping our global clients achieve stringent environmental compliance and operational cost savings. With a modern facility spanning over 10,000 square meters and a dedicated team of over 200 professionals, we combine innovative engineering with robust manufacturing to deliver evaporators that are reliable, efficient, and tailored to your unique process requirements.
Our custom-designed MVR Falling Film Evaporator represents a significant advancement in concentration and crystallization technology for ZLD systems. Unlike traditional evaporators, the MVR (Mechanical Vapor Recompression) process reuses the latent heat of vaporization, leading to exceptional thermal efficiency. The falling film design ensures a thin, uniform liquid film over the heat transfer tubes, promoting rapid evaporation at lower temperature differences and minimizing the risk of scaling or fouling. This combination is ideal for heat-sensitive or high-fouling feed streams common in industries like chemical processing, power generation, mining, and textile manufacturing.
Key Technical Features & Advantages:
- Superior Energy Efficiency: The core of the MVR system is the vapor compressor, which recompresses the secondary vapor, elevating its temperature and pressure so it can be reused as the heating steam. This dramatically reduces the need for fresh steam, often cutting energy consumption by up to 90% compared to single-effect evaporators.
- Customized Design & Scalability: Every system is engineered from the ground up based on your feed composition, desired concentration ratio, final solid content, and site-specific conditions. We design for optimal heat transfer coefficients and material compatibility.
- High Concentration Ratios: Capable of concentrating wastewater to near-saturation points, producing a minimal brine slurry for further crystallization or disposal, which is central to achieving true Zero Liquid Discharge.
- Gentle Thermal Processing: The falling film evaporation occurs at lower temperatures and with short residence times, protecting heat-sensitive components in the feed and reducing thermal degradation.
- Advanced Automation & Control: We offer integrated PLC-based control systems that continuously monitor and adjust parameters like flow rates, temperatures, pressures, and density, ensuring stable, hands-off operation and consistent product quality.
Typical Technical Specifications & Configurations:
| Parameter | Description / Options |
| Evaporation Capacity | Fully customizable, ranging from small pilot units (100 kg/hr) to large industrial systems (50+ tons/hr) |
| Heat Transfer Material | Selected based on corrosion resistance: 316L Stainless Steel, Duplex Stainless Steel, Titanium, Nickel Alloys |
| Vapor Compressor | Thermal or Mechanical (Centrifugal, Roots Blower) type selected for optimal Specific Energy Consumption (SEC) |

| Condensate Quality | Produces high-purity distillate suitable for reuse as boiler feed water or process water |
Benefits for Your Operation:
- Drastic Reduction in Operating Costs: The primary economic benefit is the massive savings on energy (steam) and cooling water, leading to a rapid return on investment.
- Environmental Compliance & Sustainability: Enables full compliance with ZLD regulations, eliminates wastewater discharge, reduces your plant's water footprint by recycling clean condensate, and minimizes waste volume for disposal.
- Recovery of Valuable Resources: In many applications, the concentrated brine can yield recoverable salts or minerals, turning a waste cost into a potential revenue stream.
- Reliable & Low-Maintenance Operation: The robust design, coupled with anti-scaling strategies and automated controls, results in high system availability and reduced manual intervention.

Frequently Asked Questions (FAQ):
-
What is the main advantage of an MVR evaporator over a traditional multi-effect evaporator for ZLD?
While multi-effect evaporators improve efficiency by using vapor in successive effects, MVR technology offers a further leap by mechanically compressing all vapor for reuse. This typically results in significantly lower specific energy consumption, often requiring only electrical energy for the compressor rather than large quantities of primary steam, making it more cost-effective for many applications. -
Can this evaporator handle high-salinity or scaling-prone wastewater?
Yes, the falling film design is inherently less prone to scaling than forced-circulation or rising film designs because of the short contact time and low temperature difference. Furthermore, the custom design allows us to specify appropriate materials, tube geometries, and integrate optional anti-scale measures like controlled blowdown or crystallizer seeding. -
How do you determine the right material of construction for our specific wastewater?
Material selection is critical. We typically request a comprehensive feed analysis and may recommend corrosion coupon testing. Based on the pH, chloride content, presence of oxidizers, and other factors, we advise on the most cost-effective and durable material, such as duplex stainless steel for high chloride environments or titanium for highly corrosive streams. -
What kind of footprint does a typical MVR Falling Film Evaporator system require?
The footprint is highly variable based on capacity and configuration. A significant advantage of the MVR design is its compactness compared to multi-effect systems, as it doesn't require multiple large vessels. We provide detailed layout drawings during the engineering phase to facilitate your plant planning. -
Is pilot testing available before committing to a full-scale system?
Yes, for new or complex feed streams, we strongly recommend pilot-scale testing. We can arrange testing on a mobile pilot unit or at our facility to gather crucial data on fouling rates, achievable concentration, and condensate quality, de-risking the full-scale investment. -
What is included in your scope of supply and services?
Our standard scope can include the complete evaporator skid (vessel, compressor, pumps, controls), detailed P&IDs and manuals, installation supervision, and operator training. We work closely with you to define the scope, which can also extend to pre-treatment, final crystallizers, or condensate polishing systems. -
How is the system controlled and monitored?
The system is designed for fully automated operation via a PLC with an HMI (Human-Machine Interface). Key parameters are monitored and controlled to maintain optimal performance. Remote monitoring and data logging options are also available for proactive maintenance. -
What is the typical delivery lead time for a custom system?
Lead time depends on the system's complexity and size. After finalizing the design, manufacturing typically ranges from 4 to 8 months. We provide a detailed project schedule upon order confirmation to ensure alignment with your project timeline.
