Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a professional manufacturer with over 10 years of experience in wastewater treatment equipment. Our Ammonia Nitrogen Wastewater MVR Evaporator is specifically engineered to efficiently treat and concentrate high-ammonia nitrogen streams, reducing volume and recovering valuable water. With a factory spanning 10,000–30,000 square meters and an annual export value of US$10–50 million, we deliver reliable, energy-saving solutions trusted by clients across North America, Europe, Asia, and Africa.
This evaporator uses mechanical vapor recompression (MVR) technology, which recycles the latent heat of vaporization, achieving up to 70–80% energy savings compared to traditional multi-effect evaporation. It is ideal for treating landfill leachate, chemical wastewater, pharmaceutical effluents, and mining drainage containing high ammonia nitrogen. The system operates at low temperatures (70–105°C) to minimize scaling and fouling, and it can concentrate the wastewater to a small volume for easier disposal or further treatment.
- Energy Efficient: MVR technology drastically reduces steam consumption; only electricity is required for the compressor.
- High Concentration Ratio: Achieves up to 50% solid content in the concentrated liquid, reducing disposal costs.
- Low Operating Temperature: Prevents thermal degradation of sensitive compounds and reduces scaling.
- Automated PLC Control: Touch-screen interface allows easy monitoring and adjustment of parameters.
- Compact Footprint: Modular design saves floor space and simplifies installation.
- Corrosion-Resistant Materials: Made of SS304 or SS316L, suitable for aggressive chemical environments.
- Flexible Capacity: Available from 100 L/h to 10,000 L/h, and customizable for larger flows.
| Parameter | Specification |
|---|---|
| Inlet NH3-N Concentration | 500 – 50,000 mg/L (customizable) |
| Outlet NH3-N Concentration | < 50 mg/L (after condensation) |
| Evaporation Temperature | 70 – 105 °C |
| Compressor Power | 30 – 500 kW |
| Water Recovery Rate | ≥ 95% |
| Noise Level | < 85 dB |
The system includes a vapor-liquid separator to effectively remove ammonia gas, which is then condensed and neutralized. Optional stripping columns can be integrated for even tighter discharge limits. Our engineers provide comprehensive support from design to commissioning, ensuring the system matches your specific wastewater characteristics.
Frequently Asked Questions (FAQ)
-
Q: What types of ammonia nitrogen wastewater can be treated?
A: Our MVR evaporator is suitable for high-ammonia streams from landfill leachate, chemical production, pharmaceutical processes, mining, and agriculture. It handles both free ammonia and ammonium salts. -
Q: How much energy does the system save compared to traditional methods?
A: Typically, MVR technology saves 70–80% of energy consumption compared to single-effect evaporation, because it recycles vapor heat instead of using live steam. -
Q: What is the maximum inlet ammonia concentration?
A: The system is designed for up to 50,000 mg/L NH3-N. For higher concentrations, pre-treatment or dilution can be arranged. -
Q: What is the expected lifespan of the compressor?
A: With proper maintenance, the compressor can last 15–20 years. We offer spare parts and remote monitoring options. -
Q: Can the system be automated?
A: Yes, it comes with a PLC-based automatic control system that adjusts temperature, pressure, and flow rates. Remote control via SCADA is available upon request. -
Q: What certifications does the equipment have?
A: Our manufacturing facilities are certified under ISO9001, ISO14000, OHSAS18001, and other quality standards. Specific product certifications can be discussed based on your market requirements. -
Q: What is the typical delivery time?
A: For a standard unit, lead time is 45–60 days. Customized solutions may take 60–90 days depending on complexity. -
Q: Do you provide on-site installation and training?
A: Yes, we offer worldwide commissioning services and operator training. Remote technical support is also available 24/7.
