Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer with over 10 years of experience in wastewater treatment and evaporation systems. Our 1 Year Warranty Vacuum Evaporator-Crystallizer is designed to deliver reliable, high-efficiency concentration and crystallization of industrial wastewater, ensuring zero liquid discharge (ZLD) while recovering valuable by-products. With on-site commissioning and training included, you can be confident that your team will operate the system safely and effectively from day one.
This advanced evaporator-crystallizer combines vacuum evaporation technology with forced circulation crystallization, enabling the treatment of high-salinity, high-hardness, and corrosive waste streams. The system operates under reduced pressure to lower the boiling point of the liquid, significantly reducing energy consumption compared to atmospheric evaporators. The crystallizer section then separates pure crystals from the concentrated brine, achieving a solid waste that is easy to handle or reuse.
Key Features & Technical Specifications
- Energy-Efficient Vacuum Operation – Operates at 40-80°C, reducing steam or electricity consumption by up to 30% compared to traditional evaporators.
- High Recovery Rate – Achieves over 95% water recovery, with the crystallizer producing dry, free-flowing crystals.
- Robust Construction – Made from high-grade stainless steel (SS304/SS316L) or other corrosion-resistant alloys, ensuring long service life even in aggressive chemical environments.
- Fully Automatic Control – PLC-based system with HMI touch screen allows for real-time monitoring, alarm management, and remote operation.
- Low Maintenance Design – Anti-scaling and anti-fouling features reduce cleaning frequency; all components are accessible for easy service.
- Customizable Capacity – Available in various sizes from 200 L/h to 20,000 L/h, tailored to your specific flow rate and concentration requirements.

Frequently Asked Questions (FAQ)
-
What types of wastewater can this evaporator-crystallizer handle?
It is suitable for high-salinity brines, RO concentrates, industrial effluents from chemical, pharmaceutical, textile, food processing, and mining industries. The system can handle solutions with high TDS, hardness, and corrosive components. Please provide a water analysis for a customized recommendation. -
How long does the on-site commissioning take?
Typically 5-10 working days, depending on the system size and site conditions. Our engineers will also train your operators for 2-3 days during the commissioning period. -
What is the energy consumption?
Energy consumption varies based on capacity and heating source. For a typical steam-driven system, the steam consumption is about 0.4-0.6 kg per kg of water evaporated. For electric heating, the power consumption is approximately 0.8-1.5 kWh per liter. We can provide energy recovery options to further reduce costs. -
Do you offer customization for different crystal sizes?
Yes, the crystallizer design can be adjusted to produce specific crystal size distribution by controlling the supersaturation, residence time, and agitation. Our process engineers can optimize the system for your target crystal quality. -
What is the maintenance requirement?
Routine maintenance includes periodic cleaning of heat exchanger surfaces, inspection of vacuum pumps, and replacement of seals. The system is designed with easy access points. We provide a detailed maintenance manual and spare parts list. -
How does the 1-year warranty work?
The warranty covers all manufacturing defects for 12 months from the date of commissioning. It includes free replacement of faulty parts (excluding consumables) and remote technical support. Extended warranty options are available. -
Can this system achieve zero liquid discharge?
Yes, combined with a pre-treatment step (if needed), the evaporator-crystallizer can achieve ZLD by evaporating all water and producing dry solids. The condensate water can be reused in your process. -
What is the delivery time?
Standard units: 30-45 days. Custom systems: 45-60 days, depending on complexity. We can also arrange expedited shipping for urgent projects.
