I.Overview
Deionized water equipment plays a key role in medium- and low-pressure boiler feedwater systems. Its core objectives are to prevent scaling, slow corrosion, improve thermal efficiency, and ensure the safe and economical operation of boilers.
II.Basic Process Flow
Raw Water→ Pretreatment → RO Reverse Osmosis →Mixed Bed (or CEDI) → Deoxygenation→ Boiler Make - up Water
III.Key water quality indicators
| Parameter | DI indicators | ||
| Hardness | 0 mmol/L | ||
| Dissolved Oxygen | <0.01 mg/L | ||
| SiO₂ | <0.01 mg/L | ||
| TDS | <0.1 ppm | ||
| pH (25°C) | 9.0–9.6 |
IV.Equipment Selection Recommendations (By Boiler Scale)
| Boiler Evaporation Capacity | Recommended Process | Water Production Reference | Payback Period | |||||
| ≤10 t/h | Softening + Mixed Bed + Thermal Deaeration | 2–5 m³/h | 1–2 Years | |||||
| 10–50 t/h | UF + RO + Mixed Bed +Membrane Degassing | 5–20 m³/h | 2–3 Years | |||||
| >50 t/h | UF + Double - stage RO + CEDI + Membrane Degassing | 20–100 m³/h | 3–4 Years | |||||
V.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
