Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a 10,000–30,000 sqm factory and 201–300 employees, proudly presents our Industrial Wastewater Treatment MVR Evaporation System — a complete Zero Liquid Discharge (ZLD) and Salt Crystallization Solution. This system is engineered to help industries meet stringent environmental regulations while recovering valuable water and salt byproducts. With annual exports exceeding US$10 million, our MVR evaporator has been trusted by clients across North America, South America, Europe, Asia, and Africa.
Our MVR (Mechanical Vapor Recompression) technology uses a compressor to recycle the latent heat of vapor, dramatically reducing energy consumption compared to traditional multi-effect evaporators. The result is a compact, efficient, and reliable system that can treat high-salinity wastewater, achieving zero liquid discharge with solid salt crystallization. Whether your effluent comes from chemical processing, oil & gas, textile dyeing, or desalination, this solution offers a sustainable path forward.
Key Features & Technical Specifications
- Energy Efficiency: MVR technology consumes only 20–30 kWh per ton of evaporated water, up to 70% less than traditional evaporators.
- Zero Liquid Discharge: All wastewater is converted into clean distillate (≥95% recovery) and dry crystalline salt, eliminating pollution discharge.
- Salt Crystallization: Integrated crystallizer produces high-purity salt suitable for reuse or safe disposal; customizable crystal size control.
- Modular Design: Skid-mounted or containerized options for easy installation and scalability from 1 TPH to 100 TPH.
- Corrosion Resistance: Constructed from stainless steel 316L or duplex materials, with optional anti-scaling coatings for harsh brines.
- Intelligent Control: PLC + HMI system with remote monitoring capability, automatic start/stop, and real-time alarms.
- Low Maintenance: Self-cleaning cyclone separator and anti-fouling heat exchanger design reduce downtime.
- Environmental Compliance: Helps meet ZLD regulations (China GB, EU, US EPA) — certifications available upon request.

Frequently Asked Questions (FAQ)
- Q: What is the minimum and maximum capacity of your MVR system? A: Our standard designs range from 1 ton per hour (24 TPD) to 100 TPD. Custom capacities can be engineered upon request.
- Q: Can the system handle high organic content or scaling-prone wastewater? A: Yes, we offer pre-treatment options (like softening, anti-scalant dosing) and advanced heat exchanger designs to minimize fouling. Each system is tailored to your specific water chemistry.
- Q: What is the typical energy consumption? A: For most brine streams, the system consumes 20–30 kWh per ton of evaporated water. The exact figure depends on TDS level and operating temperature.
- Q: Do you provide turnkey installation and commissioning? A: Absolutely. We can supply modular skids or full plant integration. Our service team supervises installation, conducts performance tests, and trains your operators.
- Q: What certifications does the equipment hold? A: Our manufacturing process complies with ISO9001, ISO14000, and OHSAS18001. Specific product certifications (e.g., CE, ASME) can be arranged at extra cost and lead time.
- Q: How long does delivery take? A: Typical lead time is 45–90 days after down payment, depending on system size and complexity. We ship from Qingdao port, China.
- Q: Can you provide references? A: Yes, we have installed systems in multiple countries. Reference lists and case studies are available upon signing an NDA.
- Q: What is the warranty period? A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranties available.
