Qingdao Conqinphi Environmental Technology Group Co., Ltd. presents our advanced 304 Stainless Steel High-Salt Wastewater Treatment Evaporator with PLC Automatic Control — a robust, intelligent solution designed for industries facing challenging saline effluents. Since 2015, our factory spanning 10,000–30,000 sqm has delivered over 200 units globally, backed by certifications including ISO9001 and ISO14000. This evaporator combines premium 304 stainless steel construction with precise PLC automation, ensuring reliable performance and minimal operator intervention for treating high-salinity streams such as RO concentrate, brine from chemical processes, and landfill leachate.
Our engineers have optimized this system to achieve consistent evaporation rates while reducing scaling and corrosion — a common pain point in salt-rich environments. The unit is modular, skid-mounted, and pre-wired for quick on-site installation. Whether you need to concentrate waste to reduce disposal costs or recover distilled water for reuse, this evaporator offers a scalable, customizable platform. Explore the technical features below.
Key Features & Technical Specifications
- Material Excellence: All wetted parts are 304 stainless steel, providing excellent resistance to chloride-induced stress corrosion in moderate salinity conditions. Optional 316L upgrade for extreme chloride levels.
- PLC Automatic Control: Siemens or equivalent PLC with HMI touchscreen provides real-time monitoring of temperature, pressure, feed flow, and liquid level. Auto-start/stop, alarm history, and remote connectivity via optional Ethernet.
- Energy-Efficient Design: Equipped with a mechanical vapor recompression (MVR) system (optional) or forced circulation to minimize steam consumption. Typical specific energy consumption: 30–60 kWh/m³ of evaporated water (dependent on feed salinity).
- Anti-Scaling Mechanism: Patented recirculation pattern and periodic auto-flush sequences reduce scaling on heat transfer surfaces, extending operational cycles between cleanings.
- Compact Footprint: Skid-mounted design reduces floor space requirement by 30% compared to conventional evaporators. Standard capacities: 1–50 m³/day (customizable).
- Easy Maintenance: Quick-opening access ports for tube bundles, removable covers, and modular pump arrangement. Maintenance downtime reduced to under 4 hours per month.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum salt concentration this evaporator can handle?
A: Our standard 304 stainless steel unit can handle feed with TDS up to 100,000 mg/L. For higher concentrations, we recommend an upgrade to 316L or duplex stainless steel, which can handle up to 250,000 mg/L. -
Q: Does the PLC control require special training for operators?
A: No. The HMI interface is intuitive with graphic screens in multiple languages. We provide a 2-day on-site training program for all operators, plus a comprehensive manual. -
Q: What is the typical evaporation efficiency (kW/m³)?
A: For an MVR system, the typical specific energy consumption is 30–50 kWh/m³. For steam-driven units, it depends on the number of effects; our multi-effect design achieves 0.2–0.4 kg steam per kg evaporated water. -
Q: Can this evaporator be used for other liquids besides brine?
A: Yes. It is suitable for various industrial wastewater streams such as chemical process liquids, pharmaceutical effluents, and landfill leachate, as long as the pH is between 4 and 10 and scaling potential is moderate. -
Q: What maintenance is required weekly?
A: Weekly tasks include checking pump seals, cleaning the mist eliminator pad, verifying calibration of temperature and pressure sensors, and inspecting the PLC panel for error logs. Detailed schedule provided in the manual. -
Q: How long does delivery take?
A: Standard units (capacity up to 10 m³/day) ship within 30–45 days after order confirmation. Custom designs require 60–90 days. We ship FOB Qingdao port. -
Q: Do you offer a performance guarantee?
A: Yes. We guarantee the evaporation capacity and effluent quality as specified in the contract. We also offer a 12-month warranty on all components and lifetime technical support. -
Q: Is remote monitoring available?
A: Yes, an optional SCADA interface allows remote monitoring and control via Ethernet or cellular modem. You can receive real-time alarms and performance reports on your smartphone or PC.
