As a leading manufacturer specialized in environmental protection equipment, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Low-Temperature Evaporation and Crystallization Equipment designed for efficient wastewater treatment and chemical recovery. With over 8 years of experience and a factory spanning 10,000–30,000 square meters, we have delivered reliable solutions to clients across North America, Europe, Southeast Asia, and more. This equipment utilizes advanced low-temperature evaporation technology to separate water from dissolved solids, enabling both clean water reuse and valuable chemical recovery—all while minimizing energy consumption and operational costs.
Our system operates at temperatures as low as 40–70°C, which significantly reduces scaling and fouling compared to traditional high-temperature evaporators. It is ideal for treating high-salinity wastewater, industrial effluents, and chemical process streams. The integrated crystallization module allows for the recovery of high-purity salts or chemicals, turning waste into profit. Whether you need to achieve zero liquid discharge (ZLD) or recover costly raw materials, this equipment offers a robust, scalable solution.
Key Features & Technical Specifications
- Low-Temperature Evaporation: Operating at 40–70°C, reducing energy consumption by up to 30% compared to conventional systems.
- Efficient Crystallization: Forced circulation or falling film design ensures uniform crystal growth and easy solid-liquid separation.
- Modular & Scalable: Customizable capacities from 100 L/h to 10,000 L/h, suitable for both small and large-scale operations.
- Automated Control: PLC-based system with HMI interface allows remote monitoring, data logging, and automatic adjustment of parameters.
- Corrosion-Resistant Materials: Constructed from SS304, SS316L, or titanium alloy to handle aggressive chemical environments.
- Energy Recovery: Optional heat pump or mechanical vapor recompression (MVR) integration for further energy savings.
- Zero Liquid Discharge Ready: Designed to achieve complete water recovery and solid waste minimization.
