Discuss the composition and value of concentrated water
Thread Content
After passing through disk filtration, ultrafiltration, and reverse osmosis, deep well water generates a certain amount of \"concentrated water\" during the reverse osmosis process. So what are the main components in this concentrated water? Is there any other value that can be utilized? Please start the discussion.
After passing through disk filtration, ultrafiltration, and reverse osmosis, deep well water generates a certain amount of \"concentrated water\" during the reverse osmosis process; this concentrated water contains mainly concentrated salts such as calcium, magnesium, chlorine, sulfate, carbonate, and other ions, which have little immediate practical value.
After passing through disk filtration, ultrafiltration, and reverse osmosis, deep well water produces a certain amount of \"concentrated water\" whose main components are high concentrations of salts, as well as ions such as calcium and magnesium. This concentrated water can only be used as spray water to eliminate dust. If utilization is to be achieved, triple-effect evaporation using steam to separate ions from concentrated water is the only option; this approach requires substantial investment, with the treatment cost reaching hundreds of yuan per ton of concentrated water. So, no one invests in utilizing it.
The concentrated water from our company is mainly used as fire-fighting water, water for cleaning equipment, and water for washing purposes in domestic use.
Concentrated water needs to be treated differently based on its grade; if it is grade 1 concentrated water, it can be recycled as makeup water for circulation systems. For grade 2 concentrated water, it can be heated with steam and stored in an open tank, after which it can be reused after sedimentation.
