Industrial Deionized Water Systems for Cosmetics & Manufacturing (2025 Guide)
1. What is a Deionized Water System?
Deionized (DI) water = RO-purified water with ions removed
• Key purity levels: 0.1–18 MΩ·cm (ultrapure)
• Industry names:
• Cosmetics: "Purified water" (USP/EP standards)
• Electronics: "18 Megohm water"
✔ Replaces traditional distillation – 60% lower operating costs
2. How RO/DI Systems Work
Core Technology
• Reverse Osmosis (RO): Removes 99% impurities (TDS <10ppm)
• Ion Exchange/EDI: Polishes to ultrapure levels
System Recovery Rates
| System Size | Recovery Rate |
|---|---|
| Small-scale | 50-60% |
| Industrial | 75-90% (optimized membrane staging) |
*Design Tip: Multi-stage RO + EDI achieves >95% recovery*
3. 5 Standard Process Flows
Option 1: Basic RO System
Source → Sand Filter → Carbon Filter → RO → DI Tank
*(For cosmetics, 1-5 MΩ·cm)*
Option 2: RO + Softening
Source → Softener → RO → DI Tank
*(Prevents scaling, 5-10 MΩ·cm)*
Option 3: RO + Mixed Bed
RO → Mixed Bed Resin → 15-18 MΩ·cm
(Electronics/Pharma grade)
Option 4: Two-Stage RO
1st RO → pH Adjustment → 2nd RO → 10-15 MΩ·cm
Option 5: Full Ultrapure (RO+EDI)
RO → EDI → 18 MΩ·cm
(Highest purity, zero chemicals)
4. Key Technical Specifications
