Recommendations for technologies for salt recovery from desulfurization wastewater
Thread Content
Hello everyone, does anyone with experience have any recommendations for a technical provider? Additionally, what are the prospects for the current salt extraction process? Is it the best process for treating desulfurization wastewater?
Ammonium salts or sodium salts? Technical exchange QQ: 1123267744
Never mention salt – it will kill you; it’s better to produce acid instead.
Salt cannot be mentioned; it’s impossible to deal with it. I saw a factory in Tianjin that deals in salt; its freight yards and warehouses are all filled to capacity with no space left. No one wants this thing.

Most mixed salts such as sodium sulfate and sodium thiosulfate are too cheap to sell； The salt extraction equipment has been installed, and the funds cannot be recovered ； There are now also newly developed processes for using desulfurization waste liquid and sulfur paste to produce acid, and these processes can be considered quite mature
Neither ammonium salts nor sodium salts sell well.
