As a leading manufacturer in the environmental protection equipment industry, Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established in 2015) proudly presents our state-of-the-art Chemical Plant Wastewater Treatment MVR Evaporator, specifically engineered for high salinity brine concentration. Our factory, spanning 10,000–30,000 square meters, with over 200 skilled employees and an annual export value of US$10 million – US$50 million, ensures that every unit we deliver meets rigorous quality standards. This MVR evaporator utilizes mechanical vapor recompression technology to dramatically reduce energy consumption while achieving efficient concentration of high-salinity wastewater, turning a costly disposal problem into a recoverable resource. Trust our proven expertise to provide a reliable, cost-effective solution for your chemical plant's wastewater challenges.
Key Product Features & Technical Specifications
Our MVR evaporator is designed with the chemical industry's most demanding conditions in mind. Below are the core features that set it apart from conventional evaporation systems:
- Energy Efficient: The mechanical vapor recompression process recycles latent heat, consuming only 30–60 kWh per ton of water evaporated — up to 80% less energy than traditional multi-effect evaporators.
- High Concentration Capability: Handles feed brine with TDS (Total Dissolved Solids) from 3% up to near saturation (25%–35% depending on salt type), producing a concentrated slurry or crystal slurry for further processing.
- Corrosion-Resistant Materials: All wetted parts are made from premium stainless steel (304, 316L, or duplex 2205) or customized alloys, ensuring long service life even with aggressive chlorides.
- Fully Automatic PLC Control: Integrated Siemens or Schneider PLC with touch-screen interface allows remote monitoring, real-time data logging, and automatic adjustments to maintain stable operation under varying feed conditions.
- Compact Modular Design: Skid-mounted units minimize on-site installation time and footprint, making it ideal for retrofit projects or limited space.
- Low Maintenance: Self-cleaning options (e.g., forced circulation or scraped surface) reduce scale formation, and the robust compressor design ensures years of trouble-free service.

Advantages & Customer Benefits
Our MVR evaporator delivers tangible benefits for chemical plant operators:
- Reduced Operating Costs: By recovering up to 95% of the latent heat, you slash steam consumption by 70–80%, leading to rapid payback periods (often under 2 years).
- Zero Liquid Discharge (ZLD) Ready: Combined with a crystallizer, the system can achieve near-total water recovery, minimizing waste volume and meeting stringent environmental regulations.
- Increased Plant Uptime: Robust construction and intelligent anti-scaling design reduce cleaning frequency; typical uptime exceeds 95%.
- Flexible Processing: Handles a wide range of salt types (NaCl, Na₂SO₄, MgCl₂, etc.) and can be tuned for different wastewater chemistries.
- Safe & Environmentally Friendly: Closed-loop operation minimizes emissions, and the system is equipped with multiple safety interlocks (pressure, temperature, vibration).
With over 100 units successfully installed worldwide in industries such as petrochemical, pharmaceuticals, textile dyeing, and landfill leachate treatment, our MVR evaporator has proven its reliability and efficiency.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum salinity the MVR evaporator can handle?
A: Our system can handle feed brine with TDS up to 28% (near saturation) depending on the salt type. For higher salinity, a pre-concentration or crystallizer stage can be integrated. -
Q: How much energy does it consume compared to traditional evaporators?
A: Typical power consumption is 30–60 kWh per ton of water evaporated, which is 70–80% less than conventional multi-effect evaporators. Actual savings depend on feed characteristics and operating conditions. -
Q: Can the system handle multiple salt mixtures?
A: Yes, the MVR evaporator is designed for complex brine chemistry. We can customize the heat exchanger design and anti-scaling measures based on your wastewater analysis. -
Q: What materials are used for corrosion resistance?
A: Standard options are stainless steel 304, 316L, or duplex 2205 for chloride-rich streams. For extremely aggressive environments, we can use titanium or high-nickel alloys upon request. -
Q: Is the system fully automatic? Can I monitor it remotely?
A: Yes, the PLC-based control system supports remote monitoring via Ethernet or optional wireless modules. You can track performance, set alarms, and adjust parameters from a control room or mobile device. -
Q: What is the typical delivery time for a unit?
A: For standard capacities, delivery is usually 60–90 days after order confirmation. Custom configurations may require 90–120 days depending on complexity. -
Q: Do you provide installation and commissioning services?
A: Yes, we offer on-site supervision, installation guidance, and commissioning by our experienced engineers. Training for your operators is also included in the package. -
Q: Can I get a pilot test before purchasing?
A: Absolutely. We have a mobile test unit available for on-site trials, or you can send a sample to our test center for a feasibility report. This helps us design the optimal system for your specific brine.
