Demineralize Su Nedir? | What is Demineralized Water?

Kısa cevap / Short answer: Demineralized water is water from which dissolved minerals (cations and anions) have been removed, typically achieving conductivity of 1–10 µS/cm depending on the treatment design.

What is Demineralized Water?

Demineralized (deionized) water protects boilers, turbines and process equipment from scale and corrosion. It is produced by ion-exchange demineralization (cation + anion columns), RO-based demin plants or RO + EDI combinations.

Eurotech Water supplies boiler feed water treatment packages for industrial and power applications.

How is Demineralized Water Produced?

1. Ion Exchange Demin Plant

Strong-acid cation resin in H⁺ form and strong-base anion resin in OH⁻ form remove Ca²⁺, Mg²⁺, Na⁺, Cl⁻, SO₄²⁻ and silica. Twin-bed or mixed-bed polish stages refine quality.

2. RO-Based Demin

High-rejection RO reduces TDS by 97–99%; optional EDI or mixed bed achieves boiler-grade conductivity.

Quality Targets

Storage and Handling

Demineralized water absorbs CO₂ from air, increasing conductivity. Use lined tanks, nitrogen blanket or on-line polish loops for critical applications.

Sıkça Sorulan Sorular (FAQ)

What is demineralized water?

Demineralized water (deionized water) has most dissolved minerals removed, typically achieving conductivity below 10 µS/cm depending on the treatment train.

Demineralize su nasıl elde edilir?

RO + iyon değişimi (kation/anyon reçine veya EDI) veya çift kademeli RO ile üretilir.

Demineralize su ile saf su farkı?

Saf/ultrapure su daha sıkı kalite limitleri (çok düşük iletkenlik, düşük TOC) gerektirir; demineralize su kazan besleme ve genel proses için yeterli olabilir.

Hangi endüstriler demineralize su kullanır?

Enerji santralleri, kazan daireleri, kimya, gıda ve otomotiv sektörleri demineralize su tüketir.

Demineralize su depolama?

CO₂ absorpsiyonunu önlemek için nötr aniyon reçineli polish veya azot blanketing önerilir.
