Qingdao Conqinphi Environmental Technology Group Co., Ltd., a professional manufacturer established in 2015 with a 10,000–30,000 m² factory and over 200 employees, brings you the Industrial Wastewater Treatment MVR Forced Circulation Crystallization Evaporator. This advanced system is engineered to achieve maximum water recovery and salt crystallization from high-salinity industrial wastewater, significantly reducing operational costs compared to traditional multi-effect evaporation. Combining forced circulation technology with mechanical vapor recompression (MVR), our evaporator delivers energy efficiency, stable crystallization, and minimal scaling—ideal for industries pursuing zero liquid discharge (ZLD).
Core Technical Description
- MVR Principle: Latent heat from vapor is recycled by a compressor, raising its temperature and pressure for reuse as heating steam. This eliminates the need for external steam supply under normal operation, reducing energy consumption by up to 70% compared to traditional evaporation.
- Forced Circulation Design: A large-flow axial pump circulates the liquor through the heat exchanger at high velocity (2–4 m/s), effectively preventing salt scaling and fouling on tube surfaces. This ensures long-term stable operation even with high-TDS feed water.
- Crystallization Function: The system integrates a forced circulation crystallizer (FC crystallizer) that promotes controlled nucleation and crystal growth. Salt crystals can be harvested as dry solids, while the mother liquor is recycled for further concentration.
- Material Selection: All wetted parts are constructed from stainless steel 304/316L or duplex stainless steel depending on chloride content and temperature, ensuring excellent corrosion resistance and longevity.
- Customizable Capacity: Standard single-unit evaporation capacities range from 0.5 to 100 tons per hour. Multiple units can be combined for larger flows.

Detailed Advantages & Customer Benefits
- Energy Efficiency: The MVR compressor consumes only electricity (about 20–40 kWh per ton of water evaporated). Compared to single-effect evaporation using live steam, your operating cost can drop by 60–80%. With no external boiler required, carbon emissions are also minimized.
- Zero Liquid Discharge (ZLD) Capable: By concentrating wastewater to supersaturation and crystallizing dissolved solids, the system produces clean distillate (quality suitable for reuse) and dry salt cake. Perfect for meeting strict environmental regulations.
- Anti-Scaling & Anti-Fouling: The forced circulation loop maintains high flow velocity across the heat transfer surfaces. Even with hardness ions (Ca²⁺, Mg²⁺) or silica, scaling is drastically reduced. This extends cleaning intervals from weeks to months, lowering maintenance labor and chemical costs.
- Modular & Compact Footprint: The unit is skid-mounted with pre-piped and pre-wired components. Installation is simple and quick – just connect utilities and feed lines. Minimal site preparation required.
- Automated Operation: PLC-based control automatically adjusts compressor speed, circulation pump frequency, and discharge valves to maintain stable crystallization. Alarms and shutdowns protect the equipment. Remote monitoring via SCADA or cloud is available as an option.
- Proven Reliability: Our evaporators have been installed in dozens of projects across industries such as chemical, pharmaceutical, textile dyeing, landfill leachate, and mining. Customer feedback consistently highlights the robustness of the forced circulation design.

Frequently Asked Questions
-
Q: What is the maximum TDS (total dissolved solids) that this evaporator can handle?
A: The system is designed to handle feed water with TDS up to 250,000 mg/L (saturation point). For extremely high TDS, a pre-concentration step may be recommended. -
Q: How often does the heat exchanger need to be cleaned?
A: With forced circulation maintaining high velocity, typical cleaning intervals range from 1 to 3 months depending on feed composition. An automatic CIP (clean-in-place) system can be integrated. -
Q: Can the system handle waste containing organic compounds or oil?
A: Yes, but organic content may require pre-treatment (e.g., oil separation, biological treatment) to protect the compressor and prevent foaming. Our engineers will evaluate your water sample. -
Q: What is the typical power consumption per ton of distillate?
A: For a standard MVR system with forced circulation, the specific power consumption is approximately 20–40 kWh per ton of water evaporated, depending on the required temperature lift and compressor efficiency. -
Q: Do you offer a laboratory-scale test unit before full-scale purchase?
A: Yes, we have a pilot MVR evaporator that can process 100–500 L/h for on-site trials. We encourage clients to test actual wastewater to confirm performance and crystal quality. -
Q: What is the warranty period for the evaporator?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty options are available upon request. -
Q: Can the output crystals be reused or sold?
A: Many customers produce marketable salt (e.g., NaCl, Na₂SO₄) if purity is high. The crystal purity depends on feed composition and process control. We can design a crystal washing system to meet your purity requirements. -
Q: What is the lead time for a typical order?
A: For a standard model, lead time is 8–12 weeks after engineering approval. Custom large-capacity units may require 14–20 weeks.
