As a leading manufacturer specialized in environmental technology since 2015, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents the Multi-Effect Falling Film MVR Evaporator with Forced Circulation – a high-efficiency solution designed to tackle the toughest industrial wastewater challenges. With our factory spanning over 10,000 square meters and a dedicated team of 200+ professionals, we deliver precision-engineered evaporation systems that reduce energy consumption while maximizing recovery rates. This evaporator combines the proven benefits of multi-effect falling film technology with forced circulation to handle high-viscosity, scaling, and fouling streams, offering you a reliable path to zero liquid discharge (ZLD).
Our evaporator is built to meet rigorous international standards, backed by certifications including ISO9001, ISO14001, OHSAS18001, and more. Whether you're treating petrochemical, pharmaceutical, or food processing wastewater, this system provides exceptional thermal efficiency (up to 95% energy savings compared to traditional evaporators) thanks to mechanical vapor recompression (MVR). The forced circulation design ensures stable operation even with high solids content, while the falling film configuration minimizes residence time and fouling. Below we break down the key specifications and benefits.

Frequently Asked Questions
-
Q: What is the difference between falling film and forced circulation designs?
A: Falling film uses a thin liquid film flowing down heated tubes, ideal for low-viscosity, non-scaling liquids. Forced circulation adds a pump to recirculate the liquid at high velocity, preventing scaling and handling higher solids content. Our evaporator combines both for versatility. -
Q: Can this evaporator handle wastewater with high salt content?
A: Yes. The forced circulation design effectively manages crystallization and scaling. We recommend using SS316L or duplex stainless steel for corrosive saline feeds. The system can concentrate salt solutions up to near saturation. -
Q: What is the typical energy savings compared to traditional evaporators?
A: MVR technology saves 80-95% of steam energy. For every kilogram of vapor compressed, you recover a large amount of latent heat, drastically reducing operating costs. -
Q: What is the minimum and maximum processing capacity?
A: Standard capacities range from 500 L/h to 5000 L/h. Customized units up to 50 m³/day are available upon request. -
Q: Do you provide after-sales service and spare parts?
A: Absolutely. We offer installation supervision, training, remote support, and a full inventory of wear parts. Our global service network ensures minimal downtime. -
Q: What certifications does the product have?
A: Our manufacturing facility is ISO9001, ISO14001, OHSAS18001, and SA8000 certified. The evaporator components comply with relevant international standards. -
Q: Can the evaporator be integrated with existing wastewater treatment systems?
A: Yes. Our engineering team can design the unit to fit your footprint and connect to existing piping, power, and controls. Skid-mounted design simplifies integration. -
Q: How long is the delivery time?
A: Typical lead time is 45-60 days after order confirmation, depending on capacity and customization level. We work closely with logistics to ensure timely delivery.
