Qingdao Conqinphi Environmental Technology Group Co., Ltd., since its establishment in 2015, has been dedicated to delivering advanced environmental solutions. Our Cocurrent MVR Evaporator is specifically engineered for the demanding needs of chemical industry wastewater treatment, offering true 24/7 continuous operation. This system utilizes mechanical vapor recompression technology to dramatically reduce energy consumption while achieving high-concentration brine treatment, making it an ideal choice for zero liquid discharge (ZLD) processes. With a factory spanning over 10,000 square meters and a team of 201–300 skilled professionals, we ensure every unit is built to the highest standards of reliability and efficiency.
Our MVR evaporator operates on a cocurrent flow principle, where feed liquid and vapor move in the same direction, enhancing heat transfer and preventing scaling. This design, combined with advanced compressor technology, allows the system to reuse latent heat from vapor compression, cutting energy usage by up to 60–80% compared to traditional multi-effect evaporators. Below are the key technical specifications of our standard model:
| Parameter | Specification |
|---|---|
| Feed Flow Rate | 500 – 50,000 L/h (Custom) |
| Evaporation Temperature | 50 – 110 °C |
| Compressor Power | 45 – 500 kW (Depends on capacity) |
| Electricity Consumption | 20 – 50 kWh per ton of water evaporated |
| Material Options | SS304, SS316L, Duplex, Titanium, Hastelloy |
| Control Mode | Automatic PLC + Touch Screen (Remote monitoring optional) |
| Noise Level | ≤85 dB(A) |
Product Features & Benefits:
- Energy-Saving Design: The cocurrent flow pattern minimizes temperature differences and reduces fouling, while MVR technology recovers 95% of vapor latent heat, leading to significantly lower operational costs.
- 24/7 Continuous Operation: Robust compressor and heat exchanger design, combined with automatic cleaning cycles (CIP optional), ensure uninterrupted production for weeks or months without shutdown.
- High Concentration Ratio: Achieves up to 20–30% solids concentration in brine, facilitating downstream crystallization or disposal.
- Corrosion Resistance: Multiple material selections tailored to handle acidic, alkaline, or high-chloride wastewater typical in chemical processes.
- Compact Footprint: Modular skid-mounted design saves valuable floor space and simplifies installation.
- Intelligent Control: Real-time monitoring of temperature, pressure, and flow; data logging and remote alarm functions available.
This evaporator is specifically optimized for chemical industry wastewater containing salts, organics, or heavy metals. It can be integrated into existing treatment lines or used as a standalone unit for ZLD projects. The system complies with international safety standards and is fully customizable to meet specific site requirements.

Frequently Asked Questions (FAQ)
-
Q1: What is the typical energy saving compared to multi-effect evaporators?
A: Our MVR evaporator can reduce energy consumption by 60–80% because it compresses and reuses the vapor, requiring only electricity for the compressor rather than steam. -
Q2: Can the system handle highly corrosive wastewater from chemical plants?
A: Yes, we offer various material options including SS316L, duplex stainless steel, titanium, and Hastelloy to withstand aggressive chemicals like HCl, H2SO4, and NaClO. -
Q3: What is the maximum feed concentration allowed?
A: The system can handle feed TDS up to 150,000 mg/L, depending on the specific chemistry. Higher concentrations require pre-concentration or special design. -
Q4: How often does the evaporator need maintenance?
A: With automatic CIP cleaning and robust compressor, routine maintenance is recommended every 3–6 months. Major overhauls are typically needed every 2–3 years. -
Q5: Is the evaporator easy to integrate into an existing wastewater treatment plant?
A: Yes, our design is modular and skid-mounted. We also provide installation supervision and can customize inlet/outlet connections to match your current piping. -
Q6: What certifications does your product comply with?
A: Our evaporators are manufactured under ISO9001 quality system, and we can provide CE, ASME, or other regional certifications upon request. -
Q7: Can you provide a performance guarantee for continuous operation?
A: We guarantee 24/7 continuous operation for at least 30 days of steady running, with a 95% uptime rate under proper operating conditions. Extended warranties are available. -
Q8: What is the lead time for a standard unit?
A: Typical lead time is 8–12 weeks after order confirmation, depending on capacity and customization. Rush orders can be discussed for special projects.
