Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. As a professional manufacturer established in 2015, we specialize in advanced wastewater treatment solutions. Our Evaporation Crystallization for Wastewater Treatment system is designed to achieve Zero Liquid Discharge (ZLD), constructed with durable 304 Stainless Steel and controlled by a precise PLC system. This product represents our commitment to environmental protection, resource recovery, and operational efficiency. With a factory size of 10,000-30,000 square meters and annual export value exceeding US$10 million, we have the capability to deliver high-quality industrial equipment to clients worldwide.
Product Overview
Our Evaporation Crystallization unit is a core technology for treating industrial wastewater, especially for high-salinity or complex effluents. By combining evaporation and crystallization processes, it separates water from dissolved solids, producing clean reusable water and solid crystals. This system is ideal for industries such as chemical, pharmaceutical, textile, mining, and power generation, where strict environmental regulations demand zero liquid discharge.
Key Features & Technical Specifications
- High Efficiency Evaporation: Utilizes advanced heat transfer technology to maximize water recovery, reducing energy consumption by up to 30% compared to conventional systems.
- 304 Stainless Steel Construction: Corrosion-resistant and durable, ensuring long service life even in harsh chemical environments. All wetted parts are made of 304 SS or higher grade materials.
- PLC Automatic Control: Fully automated operation with touch-screen interface, real-time monitoring of temperature, pressure, flow rate, and liquid levels. Remote monitoring and data logging are available.
- Zero Liquid Discharge: Efficiently separates water and solids, achieving near-100% water recovery and producing dry crystalline solids that can be disposed of or reused.
- Customizable Design: Capacity ranges from 1 m³/h to 50 m³/h per unit, with modular design for easy expansion. Options include MVR (Mechanical Vapor Recompression) for energy savings.
- Easy Maintenance: CIP (Clean-in-Place) system and anti-scaling design reduce downtime and maintenance costs.

Frequently Asked Questions (FAQ)
-
Q: What types of wastewater can this system treat?
A: It is suitable for high-salinity wastewater, industrial effluents from chemical, pharmaceutical, textile, mining, and power plants. It can handle TDS up to 250,000 mg/L and high organic loads. -
Q: What is the typical water recovery rate?
A: The system can achieve over 95% water recovery, and with proper design, nearly 100% (zero liquid discharge). -
Q: How much energy does it consume?
A: Energy consumption varies with configuration. For standard forced circulation, around 80-120 kWh/m³; with MVR, it can be as low as 30-50 kWh/m³. -
Q: Is the system fully automatic?
A: Yes, the PLC control system manages all operations, including start-up, shutdown, cleaning, and alarm response. Remote monitoring is optional. -
Q: What maintenance is required?
A: Regular cleaning of the heat exchanger and scraper, lubrication of moving parts, and periodic inspection of instrumentation. The system includes a CIP (Clean-in-Place) function to minimize downtime. -
Q: Can I customize the capacity and materials?
A: Absolutely. We offer customized solutions based on your flow rate, wastewater composition, and space constraints. Materials such as 316L stainless steel, duplex, or titanium are available upon request. -
Q: What certifications do you have?
A: Our factory is ISO9001 and ISO14000 certified, and we comply with international standards for electrical and pressure vessels. Specific certifications can be provided per customer requirements. -
Q: What is the delivery time?
A: Typically 30-60 days after order confirmation, depending on configuration and quantity. We can expedite for urgent projects.
