Demineralized (DM) water, also known as demiwater, is characterized by low conductivity (typically 0.1-1.0 µS/cm)

 Demineralized (DM) water, also known as demiwater, is characterized by low conductivity (typically 0.1-1.0 µS/cm) and low total dissolved solids (TDS) (less than 10 mg/L) due to the removal of minerals and salts. 

Here's a more detailed breakdown of DM water quality:

What is DM Water? 

DM water is produced by removing minerals and salts (ions) from regular tap water. 

This process is achieved through techniques like ion exchange or distillation. 

Key Characteristics: 

Low Conductivity: DM water has a very low electrical conductivity, typically ranging from 0.1 to 1.0 µS/cm. 

Low TDS: The total dissolved solids (TDS) content is also very low, usually below 10 mg/L. 

Neutral pH: DM water has a neutral pH, typically between 6.5 and 7.5. 

Applications: 

DM water is used in various applications, including: 

Rinse water 

Boiler water 

Cooling water 

Test water 

Battery water 

Industrial processes 

Aquariums 

Comparison to Deionized (DI) Water: 

While both DM and DI water are highly purified, DI water is produced using more advanced methods like mixed-bed resins or electro-deionization (EDI) for even higher purity. 

DI water typically has a conductivity less than 0.5 µS/cm. 

Note:

While DM water is highly purified, it may still contain trace amounts of non-ionic impurities and organic contaminants like viruses or bacteria, which can be removed through further purification processes.
