As a leading manufacturer specialized in environmental equipment, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Customized MVR Falling Film High-Temperature Vacuum Multiple Effect Evaporator for Wastewater. This advanced evaporator system is engineered to efficiently concentrate wastewater and recover valuable resources, reducing disposal costs and environmental impact. With our factory spanning 10,000-30,000 square meters and a team of 201-300 experienced professionals, we deliver tailored solutions that meet the strictest industrial standards.
Our MVR (Mechanical Vapor Recompression) falling film evaporator operates under high-temperature vacuum conditions, utilizing multiple effect design to maximize energy efficiency. The falling film technology ensures thin, uniform liquid distribution across heat transfer tubes, resulting in rapid evaporation and minimal fouling. Each unit is custom-built to handle specific wastewater characteristics, whether it is high salinity, high COD, or corrosive streams.
The key advantages of this system include significant energy savings (up to 60-70% compared to traditional evaporators), compact footprint, and reliable long-term performance. Below we detail the technical specifications and unique features that make this evaporator an optimal choice for industries such as chemical, pharmaceutical, food processing, and mining.

Product Features and Benefits:
- Energy Efficient MVR Technology: The mechanical vapor compressor reuses latent heat, drastically reducing steam consumption. Typical energy consumption is only 10-15 kWh per ton of evaporated water, compared to 60-80 kWh for traditional single-effect systems.
- Falling Film Design: Liquid flows as a thin film down the heat transfer tubes, ensuring high heat transfer coefficients and short residence time. This minimizes thermal degradation of heat-sensitive materials and reduces scaling.
- High-Temperature & Vacuum Operation: Capable of operating at elevated temperatures (up to 120°C) while maintaining vacuum conditions. This enhances evaporation efficiency and allows processing of high-boiling-point wastewater.
- Multiple Effect Configuration: Up to 6 effects can be connected in series, each utilizing vapor from the previous effect to further improve thermal efficiency. The net evaporation ratio can reach 1:1.2 (steam to water) or better.
- Customized to Your Wastewater: We analyze your wastewater composition (pH, TDS, COD, viscosity) and tailor the evaporator material, tube layout, pre-treatment, and CIP system accordingly. Options for anti-fouling coatings and enhanced cleaning are available.
- Robust Construction & Long Service Life: All wetted parts are made from corrosion-resistant alloys. The evaporator is built to withstand continuous operation with minimal maintenance. Our factory follows ISO9001 quality management to ensure durability.
- Intelligent Control & Automation: The PLC-based control system automatically adjusts temperature, pressure, feed rate, and discharge. It provides real-time data logging, alarms, and remote access via optional cloud platform.
- Eco-Friendly & Zero Liquid Discharge (ZLD) Ready: This evaporator is an integral part of a ZLD system, recovering clean water for reuse and producing concentrated brine or solid waste for disposal or further recovery.
Frequently Asked Questions (FAQ):
-
Q: What types of wastewater can this evaporator handle?
A: It is suitable for high-salinity wastewater, industrial effluents from chemical, pharmaceutical, textile, food processing, and mining industries. It can handle liquids with high TDS (up to 250,000 ppm) and moderate viscosity. Pre-treatment is required for streams with high oil, grease, or suspended solids. -
Q: How does the MVR system save energy compared to traditional evaporators?
A: Traditional evaporators require fresh steam to drive evaporation. MVR recompresses the vapor produced, raising its temperature and pressure, then reuses it as the heating medium. This recycling reduces fresh steam demand by up to 80%, lowering operating costs dramatically. -
Q: Is the system provided with a guarantee and after-sales service?
A: Yes, each unit comes with a standard 12-month warranty (extendable) covering manufacturing defects. Our team provides installation supervision, commissioning, and training. Spare parts are readily available from our Qingdao warehouse. -
Q: Can this evaporator achieve zero liquid discharge (ZLD)?
A: Yes, when combined with a crystallizer or dryer, the concentrated brine can be further processed to produce solid salts, achieving ZLD. Our system is designed for easy integration with downstream equipment. -
Q: What is the typical delivery time for a customized evaporator?
A: Delivery time depends on the capacity and complexity. Standard customized units (500-5000 L/h) are typically delivered within 60-90 days after order confirmation. Larger units may require 100-150 days. -
Q: Do you offer rental or pilot testing services?
A: Yes, we have pilot-scale MVR falling film evaporators available for on-site testing at your facility. This allows you to validate performance on your specific wastewater before committing to a full-scale unit. -
Q: What certifications does your company hold for this equipment?
A: Our manufacturing facility is certified to ISO9001:2015, ISO14001, OHSAS18001, and others. The evaporator can be designed and certified to meet international standards (ASME, PED, etc.) upon request. -
Q: Can the control system be integrated with existing plant SCADA?
A: Absolutely. Our PLC supports Modbus, Profibus, and OPC protocols, allowing seamless integration with your existing control network. Remote monitoring via GSM or Ethernet is also available.
