Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a leading manufacturer specializing in advanced zero liquid discharge solutions since 2015. Our Salt Wastewater Skid-Mounted Triple-Effect Evaporation Crystallizer is engineered to efficiently treat high-salinity wastewater, achieving near-total water recovery and solid salt crystallization. With a factory spanning 10,000–30,000 square meters and an annual export value exceeding US$10 million, we deliver robust, reliable systems trusted by industries across North America, Europe, Asia, and beyond.
This innovative system combines triple-effect evaporation with crystallization technology in a compact skid-mounted design. It is ideal for applications requiring zero liquid discharge (ZLD), such as brine concentration, petrochemical wastewater, and desalination concentrate treatment. The modular footprint saves valuable floor space while simplifying installation and maintenance.
Key Features & Technical Specifications
- Triple-Effect Evaporation: Optimized heat utilization reduces energy consumption by up to 30% compared to single-effect systems.
- Skid-Mounted Design: Pre-assembled and tested at our factory, enabling rapid on-site installation and minimal downtime.
- Automatic Control: PLC-based system with touchscreen interface allows real-time monitoring of temperature, pressure, and flow rates.
- High Recovery Rate: Achieves more than 95% water recovery, leaving dry salt crystals suitable for disposal or reuse.
- Corrosion-Resistant Materials: Constructed with 304/316L stainless steel or optional higher alloys, ensuring long service life even in aggressive saltwater environments.
- Energy Integration: Optional heat pump or mechanical vapor recompression (MVR) for further efficiency gains.
- Modular Scalability: System capacity can be customized from small pilot units to large industrial trains.

Frequently Asked Questions
-
Q: What is the typical payback period for this system?
A: Payback depends on feed TDS, energy cost, and water disposal fees. Many clients see ROI within 2–3 years due to water recovery and reduced effluent volume. -
Q: Can the crystallizer handle wastewater with organic contaminants?
A: Yes, but pre-treatment (e.g., oil separation, pH adjustment) is recommended. We design integrated pre-treatment skids upon request. -
Q: What is the expected maintenance frequency?
A: Routine inspection every 3–6 months; major cleaning of heat exchangers once per year. Our PLC system sends alerts for preventive maintenance. -
Q: Is the system compatible with existing plant utilities?
A: Absolutely. We can adapt steam supply (low pressure steam), cooling water, and electrical requirements to match your facility. -
Q: Do you provide on-site installation support?
A: Yes, we offer commissioning services with experienced engineers. Remote troubleshooting is also available 24/7. -
Q: What is the maximum feed flow rate possible?
A: Standard modules handle up to 50 m³/day per train. Multiple trains can be paralleled for larger capacities. -
Q: What certifications does the evaporator carry?
A: The system is designed and manufactured under ISO9001, ISO14001, and OHSAS18001 certified processes. Pressure vessels meet ASME/GB standards. -
Q: Can I get a sample salt analysis before purchasing?
A: We can run a lab-scale test using your actual wastewater sample to predict salt quality and crystallizer performance.
