Energy-Saving Efficient Industrial Grade 0.5-Ton Edi Ultrapure Water System

Energy-Saving And Efficient Industrial-Grade 0.5-Ton Edi Ultrapure Water System

Production Description

1. Deionization exchange: After water enters the EDI system, it first passes through the anion exchange membrane and cation exchange membrane. Under the action of the electric field, the cations in the water (e.g. Na⁺, Ca²⁺, etc.) are adsorbed by the anion exchange membrane, while the anions (e.g. Cl-, SO₄²-, etc.) are adsorbed by the cation exchange membrane. This process effectively reduces the concentration of ions in the water.

2. Desorption: After the initial deionization exchange, some of the ions that are not completely removed are further desorbed through the charged exchange resin. The resin, which is loaded with ions, is flushed by an electrolyte solution with a fixed opposite charge, causing the ions to dissociate from the resin and be replaced in the desorption solution by convection and diffusion.

3. Ions through the ion exchange membrane: under a certain current, water molecules are ionized into H⁺ and OH- ions, and these ions regenerate the failed resin, thus realizing the process of continuous water production and continuous regeneration. At the same time, the removed ions fall through the ion exchange membrane into the thick water chamber and are eventually discharged centrally.

4. Pre-treatment and post-treatment: In practice, EDI ultrapure water equipment usually also includes pre-treatment and post-treatment steps. Pre-treatment is designed to remove suspended solids, colloids, organics and other impurities in the water to protect the subsequent equipment; post-treatment may include UV sterilization, polishing resin filtration, etc. to further improve water quality.

Equipment Advantage

1. High efficiency and energy saving: EDI ultrapure water equipment does not need to regularly replace the ion exchange resin, and there is no need to add chemical reagents in the operation process, thus reducing energy consumption and environmental pollution, and improving the processing efficiency.

2. Stable water quality output: EDI process can effectively remove ions, microorganisms and organic substances in the water, to ensure that the produced ultrapure water quality is stable and in line with the relevant standards and requirements of various industries.

3. Simple operation and easy maintenance: EDI ultrapure water equipment adopts fully automatic control system, which is easy to operate and requires no professional management personnel. At the same time, its maintenance work is relatively simple, only need to carry out basic maintenance and maintenance can ensure the stable operation of the equipment for a long time.

4. Small footprint, compact structure: Compared with traditional water treatment equipment, EDI ultrapure water equipment is smaller in size and more compact in structure, which is more suitable for enterprises with limited space.

5. Environmental protection and safety: EDI ultrapure water equipment in the operation process does not produce chemical waste and secondary pollution, and has an automatic monitoring system to ensure the safety and reliability of equipment operation.
