We, Qingdao Conqinphi Environmental Technology Group Co., Ltd., have been a leading manufacturer since 2015, specializing in advanced wastewater treatment solutions. Our MVR Skid-Mounted Evaporator is designed to achieve zero liquid discharge (ZLD) in chemical plants, combining mechanical vapor recompression technology with a compact skid-mounted design for efficient and reliable operation. This system effectively reduces wastewater volume while recovering high-quality distillate, minimizing environmental impact and lowering operational costs.
At the core of our solution is Mechanical Vapor Recompression (MVR) technology, which recycles the latent heat of vaporization by compressing the vapor produced during evaporation. This process dramatically improves energy efficiency, consuming up to 80% less electricity compared to conventional multi-effect evaporators. The skid-mounted configuration integrates all critical components—evaporator, compressor, preheater, separator, and control panel—into a compact, factory-tested unit that simplifies on-site installation and minimizes footprint.

Key Features and Advantages:
- Energy Efficiency: MVR technology recycles vapor compression heat, reducing energy consumption by 60-80% and lowering operational costs significantly.
- Zero Liquid Discharge: Complete separation of solids and water produces a solid waste cake and pure distillate, meeting strict environmental regulations and enabling water reuse.
- Skid-Mounted Integration: Pre-assembled, piped, and wired in our factory, delivered as a single unit for quick on-site installation and reduced project timelines.
- Low Maintenance: Designed with anti-scaling and anti-fouling features such as forced circulation and self-cleaning mechanisms, minimizing downtime and maintenance costs.
- Customizable: Tailored to specific wastewater characteristics (pH, TDS, organic content) and required flow rates, with optional materials for corrosive streams.
- Advanced Control: PLC-based automation with touchscreen HMI provides real-time monitoring, data logging, and remote access via Ethernet, enabling predictive maintenance.
- Robust Construction: Built from high-grade stainless steel or titanium for long service life even in aggressive chemical environments.
Benefits to Customers: By adopting our MVR Skid-Mounted Evaporator, chemical plants can achieve compliance with ZLD regulations while reducing water consumption and disposal costs. The distillate can be reused in process or cooling, cutting fresh water intake. The compact skid design saves valuable floor space, and the plug-and-play nature reduces engineering and installation expenses. Additionally, the energy efficiency results in rapid payback periods, often within 1-2 years, depending on local energy prices and wastewater volume.

Frequently Asked Questions:
Q1: What is the minimum and maximum capacity range for your MVR evaporator?
A1: Our standard design covers 10-100 m³/day, but we offer customization for smaller or larger capacities based on project requirements. Pilot testing is available to validate performance for specific flows.
Q2: How does MVR technology achieve energy savings?
A2: Unlike traditional evaporators that use live steam, MVR compresses the vapor from the boiling process, raising its temperature and pressure. This compressed vapor then condenses, releasing latent heat back into the evaporator, drastically reducing external energy input.
Q3: Can the system handle wastewater with high TDS or scaling potential?
A3: Yes. We employ forced circulation or fluidized bed designs to prevent scaling, along with periodic cleaning modes. For extremely high TDS, we can incorporate pre-treatment or integrate with crystallizers to produce solid waste.
Q4: What is the typical power consumption per cubic meter of feed?
A4: Power consumption ranges from 20-60 kWh per cubic meter, depending on feed concentration and desired recovery. This is significantly lower than multiple-effect evaporation which can exceed 100 kWh/m³.
Q5: Do you provide remote monitoring and control?
A5: Yes. Our control system supports Ethernet connectivity and can be integrated with SCADA or cloud platforms for 24/7 remote monitoring, alarm notification, and data analytics. This feature is optional and customizable.
Q6: What are the installation requirements?
A6: The skid-mounted unit requires only a concrete foundation, electrical power supply (typically 380V/50Hz or 480V/60Hz), and connections for feed inlet, distillate outlet, and concentrate/blowdown. We provide detailed installation drawings and on-site commissioning support.
Q7: How long does manufacturing and delivery take?
A7: Standard lead time is 8-12 weeks after order confirmation and design approval. For customized systems, it may extend to 14-16 weeks. We coordinate with logistics to ensure timely shipment from Qingdao port.
Q8: What after-sales support do you offer?
A8: We provide 12-month warranty, spare parts availability, remote technical support, and optional maintenance contracts. Our service team can visit site for troubleshooting or scheduled inspections. We also offer training for operators.
