Regarding “well water””

Do you mean “one dose of water”?

Literally, it means “well water”. It probably refers to relatively clean water that is used for water treatment, cooling, and water replenishment; it is recommended to refer to the system’s water source.

There is also “cooling water”, “chilled water”, “demineralized water”, “fire water”, and so on

Well water, cooling water, chilled water, demineralized water, and fire water refer to well water, circulating cooling water, frozen water (which is chilled water, not chillied water), desalinated water, and fire-fighting water respectively.

Well water, that is groundwater, is better

Demineralized water is also known as soft water

Well water refers to water from wells, and is generally used as a source of water. Water that is used for various purposes after undergoing various necessary treatments.

Can well water be considered raw water? So what is the difference between chilled water and cooling water?

Cooling water is a general term for water used for cooling; things such as the circulating water used to cool machinery pumps and fresh water can all be referred to as cooling water； Chilled water generally refers to an ethylene glycol aqueous solution, which is the case with the cooling system in our workshop.

Well water is generally used as drinking water in factories; it comes from deep wells. Sometimes it is also used as a source of water for eye wash stations.

\"Cooling water\", \"chilled water\", \"demineralized water\", \"fire water\"; in my opinion, \"well water\" refers to raw water, usually groundwater. In some places, only groundwater can be used, while in other places river water is applicable. If the location of the project is not near rivers, then groundwater is the only option. “\"Cooling water\" is usually recycled cooling water, and chemicals are added to reduce corrosion in the heat exchangers. They generally contain chloride ions. Some heat exchangers are made of stainless steel. To reduce the corrosion of stainless steel caused by chloride ions, these heat exchangers are cooled using self-circulating water or specific water, which is also cooling water; however, this water is referred to as “chilled water,” with some also translating it as recycled cooling water. “\"Demineralized water\" refers to water that has had its minerals removed; it is mainly used in the United States. It is water of high purity with very low salt content, obtained by using ion exchange resins to remove ions such as calcium, magnesium, chlorine, and sodium from the raw water. This results in water that contains only a small amount of oxygen and trace ions. In Europe, such water is referred to as \"polished water\". Fire water is the commonly used water for firefighting. Water that has been slightly purified from raw water and is used for extinguishing fires.

I first heard that DW is mainly used in the USA, while PW is used in EURO. Chillied? The word construction is quite similar.

In large-scale chemical plants, the water systems are quite complex. Cooling water is circulating cooling water that is cooled using outdoor air-cooled towers; chilling water is chilled water that circulates through refrigeration units, with a temperature generally below 12 degrees. DM water is demineralized water with a high level of purity, and it is also different from the soft water used in boilers.

Sorry, “chilled water” was typed incorrectly; it should be “chilled water”. The “well water” as I understand it appears in a melamine manufacturing process. In this process, the amounts of “CW”, “Demi W” and “well water”, etc., are mentioned.

well water: water from wells

That is, softened water, or it can also be called deionized water?
