Industrial Crystallizer Wastewater MVR Forced Circulation Evaporator
Product Spotlights
As a leading manufacturer with over 9 years of expertise in environmental technology, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Industrial Crystallizer Wastewater MVR Forced Circulation Evaporator. This system is engineered to achieve zero liquid discharge (ZLD) by efficiently concentrating and crystallizing high-salinity, high-COD industrial wastewater. With a factory spanning 10,000–30,000 square meters and an annual export value exceeding US$10 million, we deliver robust, energy-saving solutions trusted across North America, Europe, Asia, and beyond.
Our MVR forced circulation evaporator integrates mechanical vapor recompression technology to recycle latent heat, dramatically reducing energy consumption compared to traditional multi-effect evaporators. The forced circulation design prevents scaling and fouling, ensuring steady operation even with challenging slurries. Below we detail the key features, technical specifications, and customer benefits that make this equipment a smart investment for industrial wastewater treatment.
- Energy Efficiency: MVR technology reuses vapor compression, saving up to 80% energy versus conventional evaporators.
- Anti-Scaling Design: Forced circulation maintains high flow velocity, minimizing crystal deposition on heat transfer surfaces.
- High Solids Handling: Capable of concentrating slurries up to 40% total dissolved solids (TDS) for effective crystallization.
- Compact Footprint: Modular skid-mounted design reduces installation space and site work.
- Automated Operation: PLC + HMI with remote monitoring, alarms, and data logging for minimal operator intervention.
- Corrosion Resistance: Available in stainless steel 316L, duplex, or titanium for aggressive chemical environments.
- Customizable: Tailored to specific wastewater characteristics (pH, salinity, organic content).

Frequently Asked Questions
-
What types of wastewater can this evaporator handle?
It is designed for high-salinity, high-COD industrial wastewater typical of chemical, pharmaceutical, textile, mining, and landfill leachate applications. It effectively processes brine, sodium sulfate, ammonium chloride, and other crystallizable salts. -
How does MVR save energy compared to multi-effect evaporators?
MVR reuses the latent heat of vaporized water by compressing the vapor to a higher temperature and pressure, then recycling it as heating steam. This eliminates the need for external steam supply, cutting energy consumption by up to 80%. -
Is the system fully automated?
Yes, it comes with a PLC + HMI control system that monitors temperature, pressure, flow, and compressor speed. Remote monitoring via Ethernet is optional. -
Can the equipment handle fluctuating feed compositions?
Our forced circulation design maintains high turbulence, reducing fouling risk even when feed TDS or viscosity changes. However, we recommend a pre-treatment step (e.g., softening) for extremely hard water to optimize performance. -
What is the typical lifespan of the evaporator?
With proper maintenance, the equipment can exceed 20 years. Key components like the compressor and heat exchanger are built with industrial-grade materials and are serviceable. -
Do you provide installation and training?
Yes, we offer on-site installation supervision, commissioning, and operator training as part of our standard service package. Extended warranties are available upon request. -
What certifications does your equipment have?
Our manufacturing facility holds ISO9001 (quality), ISO14000 (environment), OHSAS18001 (occupational health), SA8000 (social accountability), and others. Specific product certificates can be provided based on destination country requirements. -
How is the crystalline solid discharged?
The crystallized salt is continuously discharged via a bottom outlet. A centrifuge or filter press can be integrated for dewatering, depending on the required dryness.
