What is the treatment method for a dilute salt acid at a concentration of about 10%?

Everyone share their opinions! Let’s see what good ways there are to deal with this
Getting rid of salt and acid through treatment is a good approach; conventional methods generate wastewater and solid waste, so it’s better to sell them directly. . . Are there any special methods?
No. If sold directly, it is mainly aimed at pickling manufacturers. But the water resulting from pickling is likely to be handled in no proper way either; in fact, it has significant drawbacks. It’s just that environmental protection isn’t taken into account.
If it can’t be sold on the market, the neutralization method can be used.
The saline water and solid waste generated by neutralization require extremely high treatment costs. Environmental protection is strictly enforced here.
It can be recycled, but currently, there’s so much of this low-purity salt and acid on the market that no one wants to buy it, even at a premium price.
For small quantities, it is sent directly; for larger quantities, acid recovery is considered. Try the salt-acid hydrolysis method
