Modular Multi-Effect Evaporator for Seawater Desalination, 10-Effect, Automated Control Panel, ISO Standard Compliant
Product Spotlights
Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Modular Multi-Effect Evaporator for Seawater Desalination – a 10-effect, high-efficiency system designed to meet the growing demand for fresh water in coastal and industrial applications. As a manufacturer with over 9 years of experience and a factory spanning 10,000-30,000 square meters, we have engineered this evaporator to deliver reliable performance, energy savings, and easy scalability. The integrated automated control panel ensures precise operation, while modular construction allows for flexible capacity expansion. Backed by ISO standard compliance, this system is built to international quality benchmarks.
Key Features & Technical Specifications
- 10-Effect Thermal Efficiency: Achieves high Gained Output Ratio (GOR) – typically 8-10 kg distillate per kg steam – reducing energy consumption significantly compared to single-effect systems.
- Modular Design: Pre-assembled skid-mounted modules allow for quick on-site installation, minimal civil work, and future capacity upgrades. Each module is factory-tested before shipment.
- Automated Control Panel: PLC-based system with HMI touch screen monitors temperature, pressure, flow rates, and conductivity in real time. Automatic alarms, data logging, and remote monitoring capabilities are available upon request.
- Corrosion-Resistant Materials: Standard construction uses stainless steel 316L for evaporator bodies; titanium tubes are optional for high-chloride environments. This ensures long service life in harsh seawater conditions.
- Low Scaling & Fouling: Advanced spray nozzle design and precise temperature control minimize scaling on heat transfer surfaces, reducing maintenance frequency and chemical dosing.
- Energy Recovery Options: Can be integrated with thermal vapor compression (TVC) or mechanical vapor compression (MVC) to further improve efficiency – customizable per project.
- Compliance with International Standards: Designed and manufactured in accordance with ISO 9001, ISO 14000, and other relevant quality and environmental management systems. Each unit undergoes rigorous inspection.

Frequently Asked Questions
-
Q: What is the typical recovery rate of this 10-effect evaporator?
A: The recovery rate (distillate/feed) is generally 35-45% for seawater, depending on feed temperature and salinity. Higher recovery can be achieved with additional pretreatment. -
Q: Can the system handle high-salinity brine or produced water?
A: Yes, the design can be adapted for brine with TDS up to 70,000 ppm using optional materials and customized operating parameters. Please provide your water analysis for a tailored solution. -
Q: What is the delivery time?
A: Standard lead time is 90-120 days after order confirmation, depending on capacity and customization. Rush orders are negotiable with our production team. -
Q: Do you offer installation supervision?
A: Yes, we provide experienced engineers for on-site installation guidance and commissioning support. Travel and accommodation costs are quoted separately. -
Q: What kind of pretreatment is required?
A: We recommend conventional pretreatment (media filtration + cartridge filtration) to remove suspended solids and chlorine. For seawater with high organic content, additional UF or DAF may be needed – our team can design the full system. -
Q: Is the automated control panel compatible with SCADA?
A: Yes, the PLC supports Modbus TCP/IP protocol, allowing integration with existing SCADA or DCS systems. Remote monitoring via Ethernet is optional. -
Q: What is the warranty period?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty plans are available. -
Q: Can you provide performance guarantee?
A: We guarantee product water quality (
