Continuous Electrodeionization System for Ultrapure Water Production | 2-Stage RO + EDI Process

Our electrodeionization system is installed downstream of a reverse osmosis (RO) system to produce stable ultrapure water, replacing the traditional mixed bed ion exchange (MB-DI) technology. Compared with conventional ion exchange methods, this electrodeionization system offers several advantages:

  • Stable water quality for sensitive applications.
  • Easy to implement fully automated control.
  • Continuous operation without shutdowns for regeneration.
  • No chemical regeneration required, making it environmentally friendly.
  • Low operating costs.
  • Compact footprint, saving installation space.
  • No wastewater discharge.
    This electrodeionization system is widely used in industries where ultrapure water is essential, providing reliable, cost-effective, and low-maintenance water treatment solutions.

Continuous Electrodeionization system—are mainly applied in industries with extremely high water quality requirements, including:

  • Electronics industry: Semiconductor and integrated circuit manufacturing require ultrapure water for wafer cleaning to prevent impurities from affecting product performance.

  • Photovoltaic industry: In solar cell production, ultrapure water is used for silicon wafer cleaning and etching processes.

  • Pharmaceutical industry: Certain high-end pharmaceutical applications require ultrapure water as raw water or for critical cleaning procedures.

  • Laboratory research: Analytical experiments and precision instrument cleaning demand strict water quality, and EDI systems provide a stable source of ultrapure water for these environments.

FAQ

Are your water treatment systems all standard, or do they need to be customized?

For small capacities from 250 LPH to 3000 LPH, most systems are standard, but we adjust the production according to the customer’s local voltage and frequency. For larger capacities, we design the system based on the raw water quality.

Yes, that’s possible. Some of our customers already operate this way. It can significantly reduce your sea freight cost, and in some countries it can even help lower import duties.

For small systems, installation is very simple, and we provide detailed documentation so customers can handle the installation themselves. For large systems, we can provide on-site installation services, but the customer needs to cover the travel and accommodation expenses for the installation personnel.

Yes, we provide a free goods inspection service. If your supplier is within 200 km of our company (Chengdu), even the transportation cost will be covered by us. If the distance is more than 200 km, only the transportation and hotel costs will be borne by you.

Yes, for each item, there will be a minimum order quantity, and then we can produce an OEM order for you.

  • Yes, whether they are water- or wastewater-related products, we can source them for you. We have been working in the water and wastewater fields for more than 10 years.
