Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a professional manufacturer with over 8 years of experience in environmental equipment. Since 2015, we have been dedicated to providing high-quality low-temperature evaporation and crystallization systems that help industries achieve zero liquid discharge (ZLD) while reducing energy consumption. Our system comes with a Mill Test Report (MTR) for every unit, ensuring material traceability and quality assurance. Backed by our comprehensive after-sales service support, you can rely on us for long-term operational efficiency.
This low-temperature evaporation and crystallization system is designed to treat industrial wastewater, brine solutions, and chemical streams at temperatures as low as 40°C, significantly reducing energy costs compared to traditional thermal evaporators. The system utilizes advanced heat pump technology or mechanical vapor recompression (MVR) to achieve efficient water evaporation, leaving behind concentrated crystals that can be reused or disposed of safely. The entire process is automated, requiring minimal operator intervention.
Our equipment is built with corrosion-resistant materials (e.g., SS316L or duplex stainless steel) to handle aggressive fluids. The system includes a crystallization unit that produces dry, free-flowing crystals, eliminating the need for further dewatering. Flexible customization is available to match specific flow rates, inlet compositions, and space constraints.
Key Features & Benefits:
- Low-Temperature Operation: Evaporates water at 40-80°C, reducing scaling and fouling, and allowing use of low-grade heat sources.
- Energy Efficient: Heat pump or MVR technology recovers latent heat, cutting energy consumption by up to 70% compared to conventional systems.
- High Recovery Rate: Achieves over 95% water recovery, minimizing liquid waste volume.
- Automatic Control: PLC-based system with touch screen interface enables real-time monitoring and remote operation.
- Corrosion Resistance: All wetted parts are made of high-grade stainless steel or optional titanium for extreme conditions.
- Mill Test Report Included: Each system is supplied with a detailed MTR for all critical components, ensuring material quality and compliance.
- Comprehensive After-Sales Support: Our team provides installation supervision, commissioning, operator training, and 24/7 technical support. Spare parts are readily available.

Frequently Asked Questions (FAQ)
-
Q: What is the typical payback period for this system?
A: The payback period depends on your current disposal costs and energy prices. Many clients achieve payback within 1–3 years due to reduced waste volume and lower energy consumption. -
Q: Can the system handle high-salinity wastewater?
A: Yes, the system is designed to handle TDS up to 250,000 ppm. For extremely high salinity, we can incorporate additional pre-treatment or multiple effect stages. -
Q: Do you provide installation and commissioning services?
A: Absolutely. Our after-sales service includes on-site installation supervision, commissioning, and operator training. We also offer remote support via video calls. -
Q: What is the Mill Test Report (MTR) and why is it important?
A: The MTR is a document certifying the chemical and mechanical properties of the materials used in the system. It ensures traceability and compliance with your quality standards, which is especially important for regulated industries. -
Q: Can the system be customized for specific space constraints?
A: Yes, we offer skid-mounted and modular designs that can be tailored to fit limited footprints. Our engineers work with you to optimize the layout. -
Q: What maintenance is required?
A: Regular inspection of seals, pumps, and heat exchanger surfaces is recommended. The system is designed for low maintenance, with automatic cleaning cycles available as an option. -
Q: How long is the warranty period, and what does it cover?
A: Standard warranty is 1 year covering manufacturing defects. Extended warranties up to 3 years are available upon request. We also keep a stock of common spare parts for quick delivery. -
Q: Do you have references from similar projects?
A: Yes, we have installed systems in over 20 countries. We can provide case studies and contact references upon request, subject to confidentiality agreements.
