Waste acid adsorption
Thread Content
I would like to ask everyone: in the dye industry, where waste sulfuric acid with a concentration of around 80% is generated, can activated carbon be used to absorb the organic substances present in this acid? If that’s not possible, what materials can be used to remove the organic substances from it?
There are new membrane filtration methods; give it a search. Acid waste recovery is a meaningful project
For dye waste acid, we have a new process; feel free to contact anhaichem@163.com
It also seems suitable for treatment using the pyrolysis and regeneration process. Could the original poster tell us the specific composition as well as the amount of acid?
Has your issue been resolved, OP? There’s no way to add me on QQ: 2922383880.
How to utilize sulfuric acid produced at 78% concentration from caustic soda
For waste acid containing dry chlorine gas, vacuum concentration is generally used, allowing for recycling.
If it is near a bromine plant, it can be sold to that plant, which uses sulfuric acid and chlorine
