DI water plant (Deionized Water Plant) is a facility or system designed to produce deionized water, which is water that has had most of its mineral ions, such as cations (sodium, calcium, iron) and anions (chloride, sulfate, nitrate), removed. Deionized water is used in various industries and applications where extremely pure water is required.
Key Components of a DI Water Plant:
- Pre-Treatment System:
- Removes larger impurities and prepares the water for deionization.
- Includes sediment filters, activated carbon filters, and possibly softeners.
- Ion Exchange Resins:
- The heart of the system, where the deionization process occurs.
- Cation exchange resins replace positive ions (like Na⁺, Ca⁺⁺) with hydrogen (H⁺).
- Anion exchange resins replace negative ions (like Cl⁻, SO₄⁻²) with hydroxide (OH⁻).
- The H⁺ and OH⁻ combine to form pure water (H₂O).
- Reverse Osmosis (Optional):
- Often used as a pre-treatment to reduce the ionic load on the ion exchange resins, increasing efficiency and lifespan.
- Regeneration System:
- Uses acids (for cation resins) and bases (for anion resins) to recharge the ion exchange resins after saturation.
- Polishing Filters:
- Ensures ultra-pure water by removing any remaining impurities.
Applications of DI Water:
- Pharmaceuticals: Used in drug manufacturing and cleaning.
- Electronics: Essential for rinsing semiconductor wafers and electronic components.
- Automotive: Used in battery water and coolant formulations.
- Laboratories: Required for experiments and equipment cleaning.
- Power Plants: For steam production in boilers to avoid scaling and corrosion.
DI water is highly pure and free of conductive ions, making it critical for applications where contaminants can cause issues. However, it’s not suitable for drinking due to the lack of essential minerals.
