Two-Stage Reverse Osmosis EDI Ultrapure Water Equipment - Meets High Standard Water Requirements

In an EDI device, various ions in the incoming water are removed through the resin, purifying the water. At this stage, the principle of ion exchange is used to remove ions from the water. Since a voltage is applied across the ion exchange membrane, water molecules are electrolyzed into H⁺ and OH⁻ ions to regenerate the resin, while the ions exchanged by H⁺ and OH⁻ ions are migrated to the concentrate chamber for discharge under the action of a regulated power supply, thereby achieving continuous regeneration and continuous use.

Advantages of Two-Stage RO EDI Ultrapure Water Equipment

1. The complete set is fully equipped, with an integrated structure, occupying little space, and easy to install and use.
2. Advanced technology, reasonable design, capable of continuous production of pure water without the need for acid or alkali regeneration.
3. Good equipment performance, simple maintenance, and low operating costs.
4. Fully automatic operation with safety protection devices such as water shortage protection and low-pressure protection.
5. Efficient water production, water quality meets standards, effectively removing heavy metals, bacteria, suspended solids, etc., with water quality suitable for drinking pure water and various industrial pure water applications.
