Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015) presents our advanced Multi-Effect MVR Evaporator specifically engineered for high salinity wastewater treatment at 60Hz, 440V. As a professional manufacturer with a 10,000-30,000 m² factory and annual export value of US$10-50 million, we deliver robust, energy-saving solutions that meet global industrial standards. This system combines mechanical vapor recompression (MVR) with multi-effect design to achieve superior thermal efficiency and low operational costs, making it ideal for industries facing stringent discharge regulations or seeking water reuse.
Product Overview & Core Advantages
Our Multi-Effect MVR Evaporator utilizes a closed-loop vapor recompression cycle to dramatically reduce energy consumption compared to traditional multi-effect evaporators. By reusing latent heat from the vapor, the system can achieve a specific power consumption as low as 30-60 kWh per ton of water evaporated, depending on feed characteristics. The 60Hz, 440V electrical configuration is compatible with North American and other global power grids, ensuring plug-and-play installation. Key benefits include:
- Energy Efficiency: Up to 70% energy savings over conventional thermal evaporators.
- High Concentration Capability: Handles TDS up to 200,000 ppm or more, with final slurry concentration adjustable.
- Compact Footprint: Multi-effect vertical design saves floor space.
- Automated Operation: PLC-based control with touchscreen HMI for real-time monitoring and remote access.
- Corrosion Resistance: Constructed from duplex stainless steel or titanium for long service life.

Detailed Features & Benefits
1. Multi-Effect MVR Technology
By combining multiple evaporation effects with a mechanical vapor compressor, the system reuses energy multiple times, achieving a steam consumption of 0.01-0.03 kg steam per kg water – far lower than single-effect evaporators. This directly translates to lower electricity bills and reduced carbon footprint.
2. High Salinity Wastewater Adaptability
Designed to handle brine streams from reverse osmosis, chemical processing, oil & gas produced water, and landfill leachate. Anti-scaling and anti-fouling designs (e.g., forced circulation) are available upon request.
3. 60Hz 440V Electrical Compatibility
Standard configuration for markets like USA, Canada, Mexico, and parts of Asia. All electrical components are UL/CE compliant (subject to final choice).
4. Intelligent Automation
Real-time monitoring of temperature, pressure, flow, and conductivity. The system can automatically adjust parameters to maintain optimal performance, and alarms notify operators of any anomalies. Remote control via Ethernet is optional.
5. Easy Maintenance & Long Lifespan
Modular design allows quick access to heat exchangers and compressor. With proper upkeep, the system can operate for 15-20 years.

Frequently Asked Questions (FAQ)
-
Q: What is the typical energy consumption of this MVR evaporator?
A: The specific power consumption ranges from 30 to 60 kWh per ton of evaporated water, depending on feed TDS and desired concentration. This is significantly lower than conventional thermal evaporators. -
Q: Can it handle wastewater with high scaling potential (e.g., calcium, silica)?
A: Yes. We offer optional forced circulation design and anti-scalant dosing to minimize scaling. Pre-treatment like softening may also be recommended based on water analysis. -
Q: What is the lead time for delivery?
A: Typical lead time is 60-90 days after order confirmation, depending on capacity and customization. We can expedite for standard models. -
Q: Do you provide installation and commissioning support?
A: Yes, we offer on-site supervision and training by our experienced engineers. Remote guidance is also available. -
Q: What is the warranty period?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever arrives first. Extended warranty options are negotiable. -
Q: Is the system suitable for zero liquid discharge (ZLD) applications?
A: Absolutely. This MVR evaporator can be integrated with crystallizers or dryers to achieve ZLD. We have supplied such systems to multiple clients. -
Q: Can the voltage and frequency be modified for other regions?
A: Yes, we can customize for 50Hz / 380V or other specifications. Please inform us of your local power standards. -
Q: How do you ensure quality control?
A: We follow ISO9001 procedures, with strict raw material inspection, in-process checks, and final performance testing. Additionally, our systems are certified under OHSAS18001 and SA8000.
