Qingdao Conqinphi Environmental Technology Group Co., Ltd. presents our advanced Printing Dyeing Wastewater Treatment MVR Evaporation Crystallizer, engineered specifically for zero liquid discharge (ZLD) applications. As a dedicated manufacturer with over 200 employees and a 10,000–30,000 m² factory, we combine proven thermal separation technologies with robust mechanical design to help textile and dyeing facilities recover clean water and valuable salts. Our system reduces liquid waste volume by over 95% while producing high-purity condensate that can be reused directly in production processes.
Key Features and Technical Advantages
- Mechanical Vapor Recompression (MVR) Core – Uses a low-energy compressor to recycle latent heat, achieving energy savings of 60–75% compared to traditional multi-effect evaporation.
- Custom-Engineered Crystallization – Optimized for high-salinity printing dyeing wastewater (TDS up to 200,000 mg/L), producing separable crystal salts suitable for industrial reuse or safe disposal.
- Anti-Fouling and Scaling Design – Forced circulation configuration with special anti-scaling coatings and periodic flushing cycles ensures stable long-term operation even with complex organic/inorganic mixtures.
- Fully Automated Operation – PLC-based control with remote monitoring capability, minimal manual intervention, and real-time data logging for compliance reporting.
- Modular and Compact Footprint – Pre-assembled skid-mounted units available for capacities from 5 m³/day to 200 m³/day, reducing on-site installation time.

FAQ
-
What is the typical payback period for this system?
Based on water savings and salt recovery, most clients see a return on investment within 2–4 years, depending on local water and electricity costs. -
Can the system handle fluctuating wastewater composition?
Yes, our PLC automatically adjusts temperature and circulation rate. Pre-treatment is recommended for high organic loads to protect the compressor. -
What maintenance is required?
Routine checks include compressor oil levels, heat exchanger pressure drop, and salt discharge mechanism. A preventive maintenance schedule can be provided. -
Is the system suitable for high-turbidity or viscous waste?
We can integrate a forced-circulation design with enlarged tubes and a self-cleaning strainer to handle up to 5% solid content in feed. -
Do you offer a warranty and after-sales support?
Yes, standard warranty is 12 months from commissioning. Extended warranty and remote monitoring services are available upon request. -
What is the footprint of a 50 m³/day unit?
Approximately 12 m × 8 m × 6 m (L×W×H). Custom layouts are possible to fit existing plant space. -
Can the recovered salt be used directly in the dyeing process?
Depending on the purity (typically ≥95% NaCl equivalents), many customers reuse the salt as a dyeing auxiliary after simple refining.
