As a leading manufacturer specializing in advanced environmental solutions, Qingdao Conqinphi Environmental Technology Group leverages over 9 years of expertise to deliver the Customized MVR Evaporator System for Zero Liquid Discharge (ZLD). Our systems are engineered to tackle the most challenging industrial wastewater streams, transforming them into clean water for reuse and solid residues for safe disposal or recovery. We understand that every industrial process is unique, which is why our core offering is complete customization – designing an MVR system that fits your specific feed composition, capacity needs, and site constraints perfectly, ensuring optimal performance and maximum return on your environmental investment.
Our MVR (Mechanical Vapor Recompression) Evaporator Systems stand at the forefront of energy-efficient concentration technology. Unlike traditional thermal evaporators that consume vast amounts of steam, our systems utilize a high-efficiency centrifugal compressor to recompress the vapor generated during evaporation. This recycled vapor becomes the primary heating source, dramatically reducing the need for fresh steam or other external thermal energy.
Key Technical Features & Advantages:
- Superior Energy Efficiency: By reusing latent heat from the vapor, our MVR systems can achieve specific energy consumption as low as 20-40 kWh per ton of evaporated water, representing up to an 80% reduction compared to single-effect evaporators.
- Fully Customized Design: We analyze your wastewater characteristics (TDS, scaling potential, corrosivity, flow rate) to design a system with the optimal heat exchanger layout, compressor selection, and material specification (such as 316L stainless steel or titanium for highly corrosive streams).
- Compact & Integrated System: Our skid-mounted design incorporates preheaters, forced-circulation or falling film evaporators, separators, and compressors into a cohesive unit, minimizing footprint and simplifying installation.
- Advanced Automation: The system is governed by a sophisticated PLC control system that continuously monitors and adjusts parameters like temperature, pressure, level, and concentration, ensuring stable, hands-off operation and consistent distillate quality.
- Robust Construction for Harsh Environments: Built in our 10,000-30,000 sqm facility, all wetted parts are constructed from high-grade corrosion-resistant materials, ensuring long service life even when processing aggressive brines or chemical-laden wastewater.
Detailed Technical Specifications (Typical Range):
| Parameter | Specification Range |
| Evaporation Capacity | 1 - 200 tons of water per hour (customizable) |
| Final Concentrate Solids | Up to 60-80% (or to dryness for crystallizers) |
| Distillate Quality (TDS) | < 50 mg/L, suitable for reuse (e.g., cooling tower makeup) |
| Compressor Type | Centrifugal or Roots-type, electric-driven |
| Heat Transfer Material | 304/316L Stainless Steel, Duplex Steel, Titanium |
| Control System | PLC with HMI touchscreen, remote monitoring optional |
| Design Pressure | Customizable, typically vacuum to low positive pressure |
Tangible Benefits for Your Operation:
- Achieve Regulatory Compliance & ZLD Goals: Eliminate liquid discharge, meet stringent environmental regulations, and secure your operating license.
- Slash Operational Costs: Dramatically lower energy and cooling water consumption compared to multi-effect evaporation or crystallizers.
- Recover Valuable Resources: Produce high-purity water for internal reuse, reducing freshwater intake, and potentially recover salts or other solids.
- Reduce Waste Disposal Liability: Convert problematic liquid waste into a manageable solid, significantly cutting hauling and disposal costs and risks.
- Gain Operational Reliability: Our robust, automated design ensures continuous, trouble-free operation with minimal operator intervention.

Frequently Asked Questions (FAQ)
Q1: What types of wastewater are suitable for your MVR Evaporator System?
A: Our systems are highly adaptable and can be customized for a wide range, including RO reject brine, landfill leachate, flue gas desulfurization (FGD) wastewater, textile dyeing effluent, pharmaceutical process water, and metal finishing rinses. The key is a detailed analysis of your feedwater composition.
Q2: How does the energy consumption compare to a traditional Multi-Effect Evaporator (MEE)?
A: An MVR system is significantly more energy-efficient. While an MEE might use 100-150 kWh/ton, a well-designed MVR system typically consumes only 20-40 kWh/ton, as it recycles the vapor's energy instead of relying on fresh steam for each effect.
Q3: Can the system handle wastewater with high scaling or fouling potential?
A: Yes. We employ design strategies like forced circulation and anti-scalant dosing systems to manage scaling. The material selection (e.g., smooth titanium tubes) and operational parameters are carefully chosen based on your water analysis to minimize fouling and ensure stable operation.
Q4: What is the typical delivery time for a customized system?
A: Delivery time depends on the complexity and capacity of the system. Generally, it ranges from 4 to 8 months from order confirmation to shipment, including detailed engineering, procurement, fabrication, and testing.
Q5: Do you provide ancillary equipment and a complete package?
A: Absolutely. We can supply a complete turnkey ZLD package, which may include pre-treatment (softening, filtration), the MVR evaporator, a crystallizer or dryer for final solids, and condensate polishing, all controlled by a unified system.
Q6: How is the system controlled and monitored?
A: The system comes with a fully automated PLC control panel featuring a user-friendly HMI (Human-Machine Interface). It allows for automatic start-up/shutdown, continuous parameter monitoring, alarm management, and data logging. Remote monitoring and control options are also available.
Q7: What kind of after-sales support do you offer?
A: Our support includes comprehensive commissioning supervision by our engineers, operator training, a detailed operation & maintenance manual, and a warranty period. We also provide readily available spare parts and technical support for the lifecycle of the equipment.
Q8: Is the final distillate water pure enough for reuse?
A: Yes. The distillate from an MVR evaporator is typically very high-purity water with very low TDS (often <50 mg/L), making it suitable for many reuse applications within the plant, such as boiler feedwater makeup, cooling tower supplement, or process rinsing.
