Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a professional manufacturer with over 200 employees and a factory spanning 10,000–30,000 square meters. As an experienced supplier in the environmental protection industry, we are proud to present our MVR and TVR Evaporator for Industrial Effluent Treatment System — a highly efficient solution designed to meet the most demanding wastewater treatment requirements. Our evaporators combine advanced mechanical vapor recompression (MVR) and thermal vapor recompression (TVR) technologies to achieve significant energy savings, reduced operational costs, and reliable zero-liquid-discharge (ZLD) performance. These systems are built to handle complex industrial effluents, ensuring compliance with stringent environmental regulations while maximizing water recovery and minimizing waste.
The MVR/TVR evaporator series offers exceptional flexibility for various industries including chemical, pharmaceutical, textile, food processing, and mining. Whether you need to concentrate high-salinity wastewater, recover valuable by-products, or achieve complete water reuse, our customized solutions can be tailored to your specific effluent composition and flow rate. With robust construction using corrosion-resistant materials like SS316L or duplex stainless steel, these evaporators guarantee long service life even in aggressive environments.
Key Features & Technical Specifications
- Energy Efficiency: MVR technology reduces energy consumption by up to 70% compared to conventional multi-effect evaporators by recycling vapor latent heat. TVR systems offer an economical option when steam is available, with a typical steam economy of 1.8–2.5.
- Wide Capacity Range: Standard models from 500 L/h to 50,000 L/h water evaporation rate, with custom designs available for higher capacities.
- Automatic Operation: Fully PLC-controlled with touch screen HMI, enabling real-time monitoring, data logging, and remote control. Minimal operator intervention required.
- High Recovery Rate: Achieve up to 95–98% water recovery as high-quality distillate, suitable for reuse or discharge. Concentrated brine can be further processed or disposed of safely.
- Multi-Effect Design (TVR): 2–4 effect configurations to optimize steam usage and lower operating costs. Each effect utilizes waste heat from the previous stage.
- Anti-Scaling & Anti-Fouling: Forced circulation or falling film designs with special distributors to minimize scaling. Automatic CIP (clean-in-place) system available.
- Material Options: 316L stainless steel, duplex 2205, titanium, or Hastelloy depending on feed corrosiveness and temperature.
- Compact Footprint: Skid-mounted design for easy installation and integration into existing treatment lines.

| Steam Economy (kg water/kg steam) | N/A (equivalent to 20–30) | 1.8 – 2.5 per effect |
| Power Consumption | 30–80 kWh per ton water | 5–15 kWh per ton water |
| Maximum TDS in Feed | Up to 200,000 mg/L | Up to 150,000 mg/L |
| Control System | PLC + HMI (auto) | PLC + HMI (auto) |
Benefits to Your Business
- Lower Total Cost of Ownership: The combination of high energy efficiency and minimal maintenance leads to rapid payback — often within 12–18 months.
- Environmental Compliance: Achieve strict discharge standards (e.g., 95%.
- Scalability: Modular design allows future expansion without major re-engineering.
- Low Operator Skill Required: Automatic start/stop, self-diagnostics, and remote support make operation simple.

Frequently Asked Questions (FAQ)
-
Q: What types of industrial effluent can be treated with MVR/TVR evaporators?
A: These evaporators are suitable for a wide range of wastewater including high-salinity brine, chemical process streams, pharmaceutical mother liquor, textile dyeing effluents, landfill leachate, and mining wastewater. They can handle TDS up to 200,000 mg/L and high COD loads. -
Q: How do I decide between MVR and TVR technology?
A: The choice depends on local energy costs and steam availability. MVR is more efficient if electricity is cheap/high steam cost, while TVR is ideal when low-pressure steam is readily available. We can perform a techno-economic comparison for your specific case. -
Q: What is the typical payback period for your evaporator system?
A: Payback period varies based on capacity and operating conditions, but many customers achieve full ROI within 12–24 months due to water recovery savings and reduced disposal costs. -
Q: Can the evaporator handle scaling-prone wastewater?
A: Yes, we offer forced circulation designs with anti-scaling distributors and optional automatic CIP systems. For extremely scaling fluids, we can integrate pre-treatment like softening or anti-scalant dosing. -
Q: What is the water quality of the distillate produced?
A: Distillate typically has conductivity -
Q: Do you provide turnkey installation and commissioning?
A: Absolutely. We offer full engineering, procurement, and construction (EPC) services including civil works, piping, and electrical integration. Our team supervises start-up and trains your operators. -
Q: What is the maintenance requirement?
A: Routine maintenance includes checking compressor oil, cleaning heat exchange surfaces (if needed), and inspecting seals. With proper operation, the system runs reliably for 15–20 years. -
Q: Can the system be expanded later?
A: Yes, our modular skid design allows adding extra evaporation capacity or integration with other technologies (e.g., reverse osmosis, crystallizers) without extensive modifications.
