How many tons of fresh water are needed to produce one ton of chemical water?
By chemical water, do you mean deionized water or demineralized water? For deionized water, in facilities with high production volumes, the rate should be 1.8–2.0 tons per ton of deionized water. Additionally, this figure needs to be determined based on the salt content in the local groundwater or surface water, that is, the hardness and alkalinity of the water, as well as the process technologies used.
The original poster is a bit incorrect; firstly, it should be specified what kind of “chemical water” it is (what an interesting term!) ） ； Secondly, what type of water quality is used in this description?
If by \"chemical water\" as mentioned by the poster we mean desalinated water, then for ordinary industrial water that has only undergone simple treatment, the amount of water that comes out is essentially the same as the amount that goes in; after various anion and cation adsorption processes, very little change occurs in this amount. It is this resin that adsorbs cations and anions which needs to be regenerated; the regeneration process requires a certain amount of acids and bases as well as a relatively large quantity of deionized water. If the original poster wants to know the cost of chemical water (which I assume refers to desalinated water), the main factors to consider are the acid and alkali used for regenerating the resin, as well as the cost of desalinated water.
The general system recovery rate is around 75%
