Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a leading manufacturer of advanced evaporation and crystallization systems. Our Industrial Water Evaporator with MVR Evaporation Crystallization Features combines mechanical vapor recompression (MVR) technology with efficient crystallization, offering a sustainable solution for wastewater volume reduction and salt recovery. Designed to minimize energy consumption, this system reduces operating costs by up to 70% compared to traditional evaporators. With our factory spanning 10,000–30,000 square meters and a team of 201–300 skilled professionals, we deliver robust, customized equipment for global industries.
Key Features & Technical Specifications
Our MVR evaporator uses a compressor to raise the temperature and pressure of vapor, which then serves as the heating medium—eliminating the need for external steam. The integrated crystallization unit allows simultaneous salt precipitation and separation, ideal for achieving zero liquid discharge (ZLD). Below are the core technical parameters:
| Parameter | Value / Range |
|---|---|
| Evaporation Capacity | 500 – 50,000 L/h (customizable) |
| Operating Temperature | 60°C – 120°C |
| MVR Compressor | Centrifugal or Roots blower (energy saving ≥60%) |
| Power Consumption | 20 – 80 kWh per ton of water evaporated |
| Crystallizer Type | Forced circulation / DTB (draft tube baffle) |
| Material of Construction | SS304, SS316L, duplex stainless steel (customer choice) |
| Control System | PLC + HMI (Siemens, Mitsubishi, or custom) |
1. Energy Efficiency
- MVR technology recycles latent heat, cutting steam consumption to near zero.
- Only electric power drives the compressor; simple to operate and maintain.
- Ideal for areas with low electricity costs or abundant renewable energy.
2. Integrated Crystallization
- Simultaneously crystallizes dissolved solids (e.g., NaCl, Na₂SO₄, NH₄Cl).
- Produces dry, free-flowing crystals suitable for reuse or safe disposal.
- Optional centrifuge or filter press for solid-liquid separation.
3. Robust Design & Durability
- Wetted parts made from corrosion-resistant stainless steel or higher alloys.
- Anti-scaling design reduces fouling and cleaning frequency.
- All welding complies with ASME or equivalent standards.
4. Automated Operation
- Full PLC/SCADA control with remote monitoring capability.
- Parameters such as temperature, pressure, and density continuously adjusted.
- Alarm and safety interlock system for unattended running.
5. Flexibility & Customization
- Capacity can be scaled from pilot (500 L/h) to industrial (50,000+ L/h).
- Multi-effect MVR configuration available for extremely high concentration.
- Compatible with various feed sources: brine, RO reject, chemical wastewater, etc.
Customer Benefits
- Reduce operational costs: Save on fuel, steam, and disposal fees.
- Achieve environmental compliance: Meet ZLD regulations effortlessly.
- Recover valuable by-products: Crystalline salts can be sold or reused.
- Minimize plant footprint: Compact design reduces installation space.
- Long equipment life: High-grade materials and quality assurance.

Frequently Asked Questions
-
Q: What types of wastewater can this MVR evaporator treat?
A: It is suitable for high-salinity brines, RO reject, industrial effluents, landfill leachate, and chemical process streams. The system handles chloride, sulfate, nitrate, and other common salts.
-
Q: Is external steam required for startup?
A: No. The MVR system uses electric power to drive the compressor. A small auxiliary heater can be provided for initial warm-up, but steam is not needed during normal operation.
-
Q: What is the typical payback period?
A: Depending on energy costs and disposal fees, many clients achieve payback within 1–2 years. Our technical team can provide a customized ROI analysis.
-
Q: Can the system handle fluctuating feed flow and composition?
A: Yes. The PLC control system adjusts compressor speed and process parameters automatically. However, we recommend a buffer tank for large fluctuations to ensure stable crystallization.
-
Q: How often does the evaporator need maintenance?
A: Routine inspection intervals are 3–6 months, depending on feed quality. Cleaning of heat transfer surfaces may be required every 1–2 months for scaling-prone streams.
-
Q: Do you provide warranty and after-sales support?
A: Yes, we offer a standard 12-month warranty and extended plans. Our service team provides remote troubleshooting, spare parts, and on-site support worldwide.
-
Q: What certifications does your equipment hold?
A: Our manufacturing facility is ISO9001, ISO14000, and OHSAS18001 certified. Specific product certifications (CE, ASME, etc.) are available upon request.
-
Q: Can I test my wastewater on a pilot unit before purchase?
A: Absolutely. We have a pilot MVR evaporator in our factory for feasibility tests. We also offer rental units for on-site trials.
