Qingdao Conqinphi Environmental Technology Group Co., Ltd. is proud to present our Industrial Plate Evaporator Crystallizer for Wastewater Treatment Zero Liquid Discharge — a high-performance solution designed to help industries achieve complete water reuse and salt recovery. As a manufacturer with over 8 years of experience (established 2015), we have delivered advanced evaporation and crystallization systems to clients across North America, Europe, Asia, and Africa. Our plate-type design ensures superior heat transfer efficiency, reduced scaling, and lower energy consumption, making it the ideal choice for challenging wastewater streams such as brine, RO concentrate, and industrial effluents. With a factory size of 10,000–30,000 m² and a dedicated team of 200+ professionals, we combine engineering excellence with reliable after-sales support.
This plate evaporator crystallizer is specifically engineered for zero liquid discharge (ZLD) applications, where every drop of water is recovered and solids are crystallized for disposal or reuse. The system features a modular plate design that maximizes heat transfer surface area while minimizing footprint and maintenance. It is suitable for treating high-salinity wastewater, chemical process streams, and mining effluents. Below we detail the key features, technical specifications, and benefits that make our product a trusted choice for global industrial clients.
Key Features & Benefits
- High Efficiency Plate Heat Exchanger Design: The plate evaporator uses corrugated plates to create turbulent flow, achieving heat transfer coefficients up to 3–5 times higher than conventional shell-and-tube designs. This results in faster evaporation and lower energy consumption.
- Zero Liquid Discharge Capability: The system evaporates water to produce distilled water (permeate) and concentrates salts to near-dryness, enabling complete water recovery and minimal solid waste. The crystallizer section further reduces moisture content to below 5%.
- Anti-Scaling and Anti-Fouling Design: Special plate geometry and smooth surfaces reduce scaling and fouling, even when treating high-hardness or high-silica wastewater. Optional automatic cleaning cycles (CIP) ensure long-term stable operation.
- Modular and Compact: The plate stack is compact and can be expanded by adding or removing plates, offering flexible capacity from 1 m³/h to over 50 m³/h. The system occupies 30–50% less floor space compared to traditional evaporators.
- Low Operating Cost: With high thermal efficiency (up to 95% heat recovery when using MVR or multiple-effect configurations), the system reduces steam consumption by up to 40% compared to conventional evaporators. Optional mechanical vapor recompression (MVR) further cuts energy costs.
- Durable Material Construction: Wetted parts are made of stainless steel 316L or higher-grade alloys (e.g., duplex stainless steel, titanium) to withstand corrosive brines and high temperatures. Gaskets are available in EPDM, Viton, or PTFE.
- Automated PLC Control: The system includes a touch-screen HMI and PLC controller that monitors temperature, pressure, flow rate, and conductivity in real time. Automatic alarms and shutdown functions ensure safe operation with minimal operator intervention.
- Customizable Configuration: Available in single-effect, multiple-effect, or MVR configurations. The crystallizer can be integrated with a centrifuge, filter press, or dryer for solid handling. Tailored to meet specific wastewater chemistry and capacity requirements.

Frequently Asked Questions
-
What types of wastewater can this plate evaporator crystallizer handle?
It is suitable for high-salinity brines, RO concentrate, industrial effluents from chemical, pharmaceutical, textile, and mining industries, as well as landfill leachate. The system can handle TDS up to 250,000 ppm and is customizable for specific scaling or corrosive components. -
How does the plate design help prevent scaling?
The plate geometry creates turbulent flow and high shear stress at the surface, which reduces the precipitation of scale. Additionally, smooth plate surfaces and optional periodic cleaning mitigate scaling. For severe scaling conditions, we offer special surface coatings or plate materials. -
What is the typical water recovery rate?
In a zero liquid discharge configuration, water recovery can exceed 98% – meaning almost all incoming water is recovered as distillate, with the remaining concentrated brine sent to the crystallizer to produce dry solids. -
Can this system be integrated with existing wastewater treatment plants?
Yes, our evaporator crystallizer is designed as a modular add-on unit. It can be retrofitted into existing ponds or tanks, and the PLC control system can communicate with the plant's DCS or SCADA for seamless operation. -
What is the energy consumption compared to traditional evaporators?
Our plate design reduces energy consumption by 30–40% compared to conventional shell-and-tube evaporators. When combined with MVR (mechanical vapor recompression), the electrical energy required is only about 20–30 kWh per ton of water evaporated, depending on temperature lift. -
What after-sales support do you provide?
We offer a one-year warranty on all equipment, lifetime technical support, and a readily available spare parts inventory. Our engineers can provide on-site commissioning and training, and we offer remote diagnostics via internet connection. -
How long does it take to manufacture and deliver?
Standard lead time is 8–12 weeks from order confirmation, depending on customization and capacity. Urgent orders can be accommodated with expedited production schedules. -
Do you provide pilot testing before purchasing?
Yes, we offer rental and pilot-scale units for on-site testing. We recommend a trial to verify the performance with your actual wastewater. Typical pilot test duration is 2–4 weeks.
