Customized MVR Single/Double/Triple Effect Thin Film Evaporator for Forced Circulation Wastewater Concentration
Product Spotlights
Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a professional manufacturer with over 10 years of experience in environmental equipment. Our Customized MVR Single/Double/Triple Effect Thin Film Evaporator for Forced Circulation Wastewater Concentration is engineered to deliver exceptional performance in industrial wastewater treatment. Combining advanced mechanical vapor recompression (MVR) technology with thin film evaporation, this system offers high energy efficiency, compact footprint, and reliable concentration of challenging wastewater streams. Whether you need a single-effect unit for small-scale operations or a triple-effect configuration for maximum throughput, our team tailors every evaporator to your specific process conditions.
Key Features and Technical Advantages
- Multi-Effect Flexibility: Choose from single, double, or triple effect evaporation to balance energy consumption and capacity. Triple effect can reduce steam usage by up to 70% compared to single effect.
- Thin Film Technology: The rotating wiper system creates a thin, turbulent liquid film on the heat transfer surface, ensuring high heat transfer coefficients and minimal fouling – ideal for viscous or scale-prone wastewater.
- MVR Integration: Mechanical vapor recompression recycles latent heat, lowering operational costs significantly. Typical energy savings range from 30% to 60% compared to conventional evaporators.
- Forced Circulation Design: A dedicated circulation pump maintains high flow velocity across the heating surface, preventing solids deposition and ensuring stable concentration for high-salt or high-solids wastewater.
- Customized Configuration: Our modular design allows adjustments in material, heating area, control system, and auxiliary components (e.g., pre-heaters, condensers, vacuum systems) to match your wastewater chemistry and target concentration.
- Durable Construction: Available in stainless steel 304 or 316L, with optional anti-corrosion coatings for aggressive media. All welds meet international standards.
- Intelligent Control: PLC-based automation with touchscreen HMI enables real-time monitoring of temperature, pressure, flow rate, and concentration. Remote access and data logging are available upon request.
- Compact & Scalable: The vertical thin film design minimizes floor space, making it suitable for retrofitting into existing plants. Multiple units can be paralleled for larger capacities.

Client Benefits
- Lower Operating Costs: Reduced steam and electricity consumption through MVR and multi-effect design.
- Reduced Waste Volume: Concentrate wastewater to 20-50% solids, minimizing disposal costs.
- Improved Reliability: Forced circulation and thin film technology resist fouling and scaling, extending maintenance intervals.
- Environmental Compliance: Effective pre-concentration before downstream treatment (e.g., crystallizers, dryers) helps meet discharge or zero-liquid-discharge goals.
- Fast ROI: Typical payback period of 12-24 months based on energy and waste savings.

Frequently Asked Questions
-
Q: What is the difference between single, double, and triple effect configurations?
A: The number of effects indicates how many evaporation stages are used. Triple effect consumes the least steam per kg of water evaporated but has higher capital cost. Single effect is simplest and suited for small capacities. Double effect offers a balanced trade-off. Our engineers recommend the optimal configuration based on your feed characteristics, target concentration, and energy cost. -
Q: Can this evaporator handle high-salinity wastewater?
A: Yes, the forced circulation design maintains high flow velocity and prevents salt deposition. For extremely high salinity or scaling potential, we can add a salt removal system or use special materials (e.g., duplex stainless steel). Please provide your water analysis for a customized recommendation. -
Q: What is the typical energy consumption per ton of water evaporated?
A: It varies. For a triple-effect MVR system, the equivalent steam consumption can be as low as 0.1-0.2 tons of steam per ton of water evaporated (including electrical energy converted to steam equivalent). Single effect without MVR may consume 1.0-1.2 tons of steam. MVR reduces energy by recompressing vapor. -
Q: How long does a custom evaporator take to manufacture?
A: Typical lead time is 60-90 days after design approval, depending on complexity and current production load. We offer expedited delivery for urgent projects (subject to availability). -
Q: Do you provide installation and commissioning services?
A: Yes, we can provide on-site supervision by our engineers or detailed installation manuals. Commissioning and training are also available as optional services. Our team can also assist with integration into your existing process. -
Q: What certifications does this product have?
A: Our manufacturing facility is certified under ISO9001, ISO14000, OHSAS18001, and other management systems. The specific evaporator can be designed to meet CE, ASME, or other regional codes as requested – please specify during inquiry. -
Q: Can the evaporator be automated?
A: Absolutely. We equip the system with a PLC and HMI for automatic control of temperature, pressure, feed rate, and discharge. Remote monitoring and data logging are available options. -
Q: What is your after-sales warranty policy?
A: We offer a standard 12-month warranty on manufacturing defects and provide technical support via email, phone, or video call during the lifecycle of the equipment. Spare parts can be supplied quickly from our warehouse.
