Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a leading manufacturer with over 10 years of experience in the environmental technology sector. Our Triple-effect Evaporator Crystallizer is specifically engineered for chemical wastewater treatment with high concentration streams. Built with premium 316L stainless steel and a capacity of 800 L/h, this equipment delivers reliable, energy-efficient evaporation and crystallization for demanding industrial applications. We are proud to serve clients across North America, Europe, Asia, and beyond, with annual export values exceeding US$10 million.
This triple-effect system utilizes a multi-effect evaporation principle to maximize heat recovery and minimize energy consumption. The crystallizer function allows for the separation of dissolved solids, converting liquid waste into solid crystals and clean distillate. Designed for high-concentration chemical wastewater, the unit is corrosion-resistant, durable, and easy to operate. Below, we detail the key features, technical specifications, and benefits that make this evaporator crystallizer a valuable asset for your wastewater treatment processes.
Key Features
- Triple-effect design – Utilizes three evaporation stages, reducing steam consumption by up to 60% compared to single-effect systems.
- 316L Stainless Steel construction – Excellent resistance to corrosive chemicals, acids, and high temperatures, ensuring long service life.
- High concentration treatment – Capable of processing wastewater with high TDS (Total Dissolved Solids) up to 300,000 ppm or more, producing solid crystals.
- Compact footprint – Space-saving design suitable for both indoor and outdoor installation.
- PLC automatic control – Touch screen interface with real-time monitoring, automatic alarms, and remote communication capability.
- Low energy consumption – Thermal vapor recompression (optional) further enhances efficiency.
- Easy maintenance – Modular design for quick cleaning and replacement of parts.

Frequently Asked Questions (FAQ)
-
Q: What types of wastewater can this evaporator crystallizer treat?
A: It is designed for high-concentration chemical wastewater, including those containing salts, acids, alkalis, and organic compounds. The 316L SS material makes it suitable for corrosive streams. We recommend a sample analysis to confirm compatibility. -
Q: How much energy does the triple-effect system save compared to a single-effect evaporator?
A: Typically, triple-effect reduces steam consumption by about 60-70% because each effect reuses the vapor from the previous effect. This results in significant operational cost savings. -
Q: Can the system achieve zero liquid discharge (ZLD)?
A: Yes, when combined with a crystallizer, this system can produce solid crystals and clean distillate, enabling ZLD. The final crystal moisture content can be as low as 5-10%. -
Q: What is the maximum concentration of solids that can be handled?
A: The system can handle feed streams with TDS up to 300,000 ppm or higher, depending on the slurry properties. The crystallizer is designed to produce a pumpable slurry with up to 50-60% solids. -
Q: Do you provide installation and commissioning support?
A: Yes, we offer on-site installation guidance and commissioning services. Our engineers can travel to your site, or we can provide remote assistance via video calls. Training for your operators is also included. -
Q: What is the typical lead time for this equipment?
A: Standard lead time is 8-12 weeks after order confirmation and down payment. Custom designs may require additional time. We will provide a detailed schedule in the proposal. -
Q: Is the system customizable for different feed flow rates?
A: Absolutely. We can design the evaporator crystallizer for capacities ranging from 100 L/h to 10,000 L/h. The 800 L/h model is a standard option, but we can adjust the number of effects and heat transfer area to meet your needs. -
Q: What kind of warranty do you offer?
A: We provide a standard 12-month warranty from the date of shipment, covering defects in materials and workmanship. Extended warranties and spare parts packages are available upon request.
