Oilish impurities present the effluent discharged from the electroplating industry is normally not removed by _____________________?
Correct answer: A. Chemical coagulation
- A. Chemical coagulation
- B. Floatation & skimming
- C. Centrifugation
- D. Ultra filtration
Explanation
Chemical coagulation is primarily used to destabilise suspended and colloidal contaminants, whereas oily impurities are commonly separated by flotation, skimming, centrifugation, or membrane filtration. Coagulants can assist with emulsified oil, but they are not normally the primary oil-removal method in this context.
