How should spent molten salts used in evaporation for alkali fixation be disposed of?
Thread Content
Our factory is a company that produces solid alkali by evaporation. Due to the relocation, the existing waste molten salt used for evaporation-based alkali fixation is now available; how do those with more experience handle it?
Treat it as hazardous waste; there aren’t many good alternatives for handling it.
In accordance with requirement 6.3 of Note 1 in the \"Standards for Controlling Pollution from Hazardous Waste Landfilling (18598-2019)\\", hazardous waste materials with a total content of water-soluble salts exceeding 10% and an arsenic content exceeding 5% must be landfilled in rigid hazardous waste landfills.
