Please tell me about the more economical waste disposal method.

I would like to ask you about the method of treating chemical cleaning waste liquid, especially what method is used to treat COD, suspended solids and fluoride, which is more economical and easy to operate? Thank you in advance!
Fluoride can be precipitated and discharged by adding quicklime and flocculant to stir. . .
If the suspension is high, coagulation sedimentation or air flotation can be used. If the pH value is high, neutralization treatment is required. If the organic matter is soluble, biochemical treatment is required. Of course, if the biodegradability is poor, pretreatment is required to improve the biochemical ratio.
