As a leading manufacturer with over 8 years of expertise in environmental technology, Qingdao Conqinphi Environmental Technology Group is proud to introduce our advanced Skid-Mounted Evaporator Crystallizer Unit for Salt Recovery. Engineered for precision and reliability, this PLC-controlled system represents our commitment to providing turnkey solutions for industrial wastewater treatment and resource recovery. Designed for efficiency and ease of integration, our unit helps clients transform waste streams into valuable salt products, significantly reducing disposal costs and enhancing environmental compliance. Our experience serving global markets across North America, Europe, Asia, and beyond ensures this product is built to meet international operational standards.
Core Product Features & Technical Advantages:
Our skid-mounted evaporator crystallizer is a complete, pre-engineered package designed to simplify complex separation processes. Below are its defining characteristics:
- Integrated Skid Design: The entire evaporation and crystallization system, including pumps, heat exchangers, controls, and piping, is mounted on a single structural steel skid. This modular approach drastically reduces field installation time and costs, minimizes on-site assembly errors, and ensures system integrity.
- Intelligent PLC Control: At the heart of the unit is a sophisticated Programmable Logic Controller. This automation system allows for precise monitoring and control of critical parameters such as temperature, pressure, level, and density. Operators can run pre-set programs, receive alarms, and generate operational reports, ensuring consistent product quality and process stability with minimal manual intervention.
- High-Efficiency Evaporation: The system utilizes forced-circulation or falling-film evaporation technology (customizable based on feed) to efficiently concentrate brine solutions. This design maximizes heat transfer, minimizes energy consumption, and prevents scaling, leading to lower operational expenses.
- Controlled Crystallization: Following evaporation, the supersaturated solution enters the crystallizer where salt crystals are grown under controlled conditions. This results in uniform crystal size distribution, high purity, and easy solid-liquid separation, yielding a marketable salt product.
- Superior Material Selection: Constructed primarily from corrosion-resistant materials like 316L stainless steel or higher-grade alloys for critical wetted parts, the unit is built to handle aggressive brine chemistries and ensure a long service life, reducing maintenance frequency.
- Resource Recovery Focus: The primary benefit is the recovery of high-purity salts (e.g., sodium chloride, sodium sulfate) from industrial wastewater, turning an environmental liability into a potential revenue stream while achieving Zero Liquid Discharge (ZLD) objectives.

Frequently Asked Questions (FAQ):
-
Q: What types of wastewater or brine is this unit suitable for?
A: This unit is highly effective for treating saline wastewater from industries like chemical processing, pharmaceuticals, textile dyeing, landfill leachate, and power plant flue gas desulfurization. The specific design (materials, evaporator type) is customized based on your feed's salt composition, concentration, and impurities. -
Q: How does the skid-mounted design benefit international buyers?
A: The pre-assembled, containerized design simplifies logistics, reduces import complexity, and minimizes the need for highly specialized local installation contractors. It ensures you receive a system that has been fully tested and commissioned at our factory, significantly de-risking your project. -
Q: What is the typical lead time for such a unit?
A: Lead time depends on the capacity and customization level. Standard medium-capacity units typically have a lead time of 16-24 weeks from order to shipment, which includes detailed engineering, procurement, fabrication, and comprehensive factory acceptance testing. -
Q: Can the system achieve Zero Liquid Discharge (ZLD)?
A: Yes, this evaporator crystallizer is a core component of a ZLD system. It concentrates the brine to the point of crystallization, producing solid salt and clean water condensate. For complete ZLD, it can be integrated with a downstream dryer or additional concentrator. -
Q: What kind of after-sales support and training do you provide?
A: We provide detailed operation & maintenance manuals, P&ID drawings, and electrical schematics. We offer comprehensive training for your operators at our factory or via online sessions. Remote technical support and a supply of critical spare parts are also available. -
Q: How energy-efficient is this system compared to traditional evaporation ponds?
A: It is substantially more efficient. Mechanical evaporation recycles latent heat and operates in a closed loop, using significantly less energy per kilogram of water evaporated than open ponds, which are subject to high heat losses and large land requirements. -
Q: Is the PLC system user-friendly for operators without extensive programming knowledge?
A: Absolutely. The human-machine interface (HMI) is designed with intuitive graphics, pre-configured recipes, and clear alarm messages. Standard operations like starting, stopping, and monitoring require only basic training. Advanced parameter changes can be password-protected. -
Q: Can you assist with the initial process design and feasibility study?
A: Yes, as a solution provider, we offer preliminary engineering services. We can analyze a sample of your wastewater, conduct lab or pilot tests if needed, and provide a process flow diagram and feasibility report to ensure the system design meets your recovery and purity targets.
