Recycling of salt sludge in the chlor-alkali industry
Thread Content
I would like to ask everyone: how is the salt sludge produced by the filter presses used in the chlor-alkali industry handled, and is there any potential for reusing it? ? ? ?
Magnesium fertilizer can be produced after removing sodium chloride.

There are people who specialize in collecting salt sludge, in order to recover metals such as barium from it
Poster: Here, we have a separate filter press for the tanks, and the resulting barium sludge is taken away. The salts of other components are taken to the desulfurization and denitration areas in power plants for use.
Under normal circumstances, it should be handed over to qualified companies for landfill disposal; handling it oneself is illegal and will attract scrutiny from environmental protection authorities.
Barium salt sludge is filtered using specialized filter presses, and the resulting sludge cake is taken away; other types of salt sludge can be returned to the system for reuse
How to recycle it? Could you be more detailed?
It’s an old topic, but the problem has yet to be effectively solved.
