Electrodialysis Technology for Industrial Use

Electrodialysis is a process that uses a potential difference to drive ion migration through selective ion exchange membranes, separating salts from non-charged components in water. This technology enables processes such as desalination, concentration, purification, and more.

Electrodialysis is widely applied in various sectors, including:

• Power Generation: Enhancing efficiency in power plants.
• Thermal Automation: Optimizing thermal processes.
• Chemical and Metallurgical Industries: Improving chemical processing and metal purification.

Electrodialysis leverages direct current (DC) to facilitate the selective passage of anions and cations through ion exchange membranes, thereby transferring ions from one aqueous solution to another. This process involves:

1. Utilizing Advanced RO Membranes: The world’s most advanced reverse osmosis (RO) membranes from the USA are employed, with a filtration precision of 0.001 microns, ensuring high-quality water suitable for industrial applications.
2. Applications:
   • Suitable for industries such as manufacturing, schools, hotels, hospitals, food and beverage production, pharmaceuticals, electronics, and chemical processing.
   • Provides ultra-pure water for laboratories, power plants, glass cleaning, microelectronics, and more.

• Advanced Quiet Operation: Imported ultra-quiet diaphragm pumps ensure long service life and reliable operation.
• Multi-Stage Filtration and Purification:
  • Pre-treatment involves quartz sand, activated carbon, softening resin, and ultrafiltration membranes.
  • High-precision RO membranes remove sediments, suspended solids, colloids, organic matter, heavy metals, soluble solids, bacteria, viruses, ions, and other impurities, retaining only water molecules and dissolved oxygen.
• Automated High-Pressure Flushing: Extends the life of RO membranes through automatic flushing and control during water production.
• On-Demand Water Production: Delivers high-purity water at low cost, meeting diverse drinking and usage needs.
• Wide Range of Applications: Ideal for various settings, including industrial plants, educational institutions, hotels, hospitals, food and beverage industries, and household applications.
• Versatility: Can be integrated with end-use devices like water boilers, coffee machines, and ice makers to address water purification needs.
• Small and Large Capacity Models:
  • Small-scale models for household and commercial use include RO-50GPD, RO-100GPD, RO-150GPD, RO-200GPD, RO-400GPD, RO-500GPD, and RO-6000GPD.
  • Large-scale industrial RO systems offer capacities ranging from 0.25 tons/hour to 500 tons/hour in single and double stages.
• Customizable Solutions: Equipment can be tailored to specific water usage requirements, ensuring optimal performance for various applications.
