Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 and operating from a 10,000–30,000 m² factory, is a trusted manufacturer specializing in advanced wastewater treatment solutions. Our 220V 50Hz, 500L/h Capacity Zero-Discharge Wastewater Treatment System with MVR Evaporation is designed to help industries achieve strict environmental compliance while recovering valuable water resources. Combining mechanical vapor recompression (MVR) technology with a compact footprint, this system delivers reliable, energy-efficient zero-liquid-discharge (ZLD) performance for a wide range of industrial effluents.
This system is ideal for sectors such as chemicals, pharmaceuticals, textiles, food processing, and metal finishing, where reducing wastewater volume and eliminating discharge are critical. With a processing capacity of 500 liters per hour and operation on standard 220V/50Hz power, it offers a practical, low-energy solution for small to medium-scale operations. The MVR evaporator recovers heat from vapor, significantly lowering energy consumption compared to conventional thermal evaporation methods.
Key Features & Technical Specifications
- Zero Liquid Discharge (ZLD): Eliminates wastewater discharge by recovering clean water and concentrating waste into dry solids or slurry.
- MVR Evaporation Technology: Uses a mechanical compressor to raise vapor temperature and pressure, recycling latent heat for up to 70% energy savings compared to traditional evaporators.
- Plug-and-Play Design: Pre-assembled skid-mounted unit with integrated PLC control, requiring minimal on-site installation.
- Wide pH & Salinity Tolerance: Handles feed water with pH 2–12 and TDS up to 200,000 ppm.
- Automatic Control & Monitoring: Touch-screen interface with real-time data logging, alarms, and remote monitoring capability (optional).
- Corrosion-Resistant Construction: Main components in SS304 or SS316L, with titanium options for aggressive brines.
- Low Maintenance: Self-cleaning cycles and easy-access design reduce downtime.

Detailed Advantages & Customer Benefits
- Energy Efficiency: MVR technology reduces electricity consumption by 50–70% compared to single-effect evaporators. Typical operating cost is only $0.5–$1.0 per ton of water treated, depending on local electricity rates.
- Zero Environmental Liability: Achieve complete compliance with stringent discharge regulations. No liquid effluent means no pollution fines or reputational damage.
- Water Reuse: Recovered distilled water can be reused in processes, cooling towers, or as boiler feed, reducing fresh water intake by up to 95%.
- Compact Footprint: Skid-mounted design saves valuable floor space – ideal for plants with limited room.
- Simple Operation: Automated start/stop, self-diagnostics, and remote monitoring minimize operator intervention.
- Scalability: Single unit handles 500 L/h; multiple units can be combined for higher throughput.
- Robust After-Sales Support: Our engineering team provides commissioning, training, and 24/7 technical support.
For example, a chemical plant processing 500 L/h of high-salinity wastewater can reduce its annual disposal cost by over $50,000 while recovering 4,000 m³ of clean water per year. The system pays for itself within 18–24 months in most applications.

Frequently Asked Questions (FAQ)
-
Q: What types of wastewater can this system handle?
A: It is suitable for industrial effluents with high salinity, high COD, or high TDS, such as from chemical, pharmaceutical, textile, and food processing industries. Pre-treatment (e.g., oil removal, pH adjustment) is recommended for certain streams. -
Q: What is the typical energy consumption per hour?
A: At 500 L/h feed rate, the system consumes approximately 15–25 kW of electrical power, depending on feed characteristics and target concentration. This results in about 30–50 kWh per cubic meter of distillate. -
Q: How long does the compressor last?
A: The MVR compressor is designed for a service life of 20,000–30,000 operating hours under normal conditions. Regular maintenance (oil changes, seal inspection) can extend its life. -
Q: What is the solid content of the concentrate?
A: The system can concentrate the brine up to 20–30% total solids (depending on feed composition). With an optional crystallizer, dry solids can be achieved. -
Q: Do you provide installation and commissioning services?
A: Yes, our engineers can provide on-site installation guidance and commissioning. We also offer remote technical support for troubleshooting. -
Q: Can the system handle varying feed flow rates?
A: The PLC control adjusts the evaporation rate automatically within a range of 50–110% of the nominal capacity. For sustained higher flows, a larger unit or multiple units are recommended. -
Q: What certifications does your company hold?
A: Our factory is certified under ISO9001, ISO14001, OHSAS18001, and other international standards. Specific product certifications can be provided upon request. -
Q: What is the typical delivery time?
A: For standard 500L/h units, delivery is 30–45 days after order confirmation. Customized systems may take 60–90 days.
