Question

What are the similarities and differences between water that has been distilled and water that has been deionized using a RO device?

Answer 1

Distilled water

• Water that has been treated through the process of distillation is known as distilled water.
• involves boiling water and collecting the steam that forms in a container
• Since the components of water have different boiling points, the process is carried out multiple times.
• distillation, on the other hand, can remove more impurities than just ions.
• Distillation will remove nonvolatile molecular species, but not volatile ones
• Distillation systems are not designed to remove chlorine and other chemicals completely from water.
• water that is completely devoid of impurities and minerals.
• Distilled water systems can be more costly to maintain than RO systems.
• It needs to operate using electricity for water heating.
• it is used not just for everyday drinking or to put in appliances, it is even used in the medical field for cleaning wounds and more.
• it’s very important to have additional purification technologies—besides only distillation—to make sure all the bad stuff is removed

Deionized water

• Deionization process, only removes ions – charged non-organic particles – from the water.
• DI water is water that has had all of the ions removed
• The water should be filtered first to remove organic material, and additional filtering with a reverse osmosis (RO) system will remove a significant number of additional contaminants. This leaves only a small amount of ionized minerals for the DI system to remove.
• Deionized water is used in many industrial processes, as well as in the cosmetic and pharmaceutical industries and for laboratory purposes.DI water is typically only used for commercial purposes.

• Deionization, on the other hand, can be performed relatively quickly – especially if a mixed bed resin is used, so the water only needs to pass through one time

• Deionization does not remove molecular species (e.g., sugar) or uncharged organic particles (most bacteria, viruses).

• DI systems do not remove dissolved O2, as it is a molecular species.

Both distilled water and deionized water are pure water,but they are produced in different ways
