Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 and located in Qingdao, Shandong, China, is a leading manufacturer specializing in environmental protection equipment. With a factory size of 10,000-30,000 square meters and an annual export value of US$10-50 million, we are committed to delivering high-quality solutions for wastewater treatment. Our Multi-effect Evaporation Concentration Crystallizer for Wastewater Treatment Zero Discharge 304 SS represents the pinnacle of our engineering expertise, designed to achieve complete zero liquid discharge (ZLD) while maximizing energy efficiency. This robust system, constructed from premium 304 stainless steel, is ideal for industries facing stringent environmental regulations and high-concentration wastewater challenges.
This crystallizer utilizes multiple-effect evaporation technology to concentrate and crystallize dissolved solids from industrial wastewater, producing clean water for reuse and solid salt byproducts. The 304 stainless steel construction ensures excellent corrosion resistance and longevity, making it suitable for a wide range of chemical and saline effluents. Below, we detail its features, technical specifications, and the tangible benefits it offers to your operations.
Key Features & Technical Advantages
- Multi-effect Evaporation Design: Utilizes multiple evaporation stages to significantly reduce energy consumption, achieving steam savings of up to 50-60% compared to single-effect systems.
- Zero Liquid Discharge (ZLD) Capability: Completely eliminates wastewater discharge by recovering all water and converting solids into crystalline salts, meeting the most stringent environmental standards.
- 304 Stainless Steel Construction: All wetted parts are made from high-grade 304 SS, offering excellent resistance to corrosion from chlorides, acids, and alkalis, ensuring long service life and low maintenance.
- Automatic Crystallization Control: Integrated control system adjusts temperature, pressure, and feed rate to optimize crystal growth, preventing scaling and fouling for continuous operation.
- Flexible Configuration: Designed for both atmospheric and vacuum operation, allowing customization to match specific wastewater characteristics and energy sources.
- Compact Footprint: Modular design minimizes floor space requirements while maintaining high throughput, ideal for facilities with limited installation area.
