Question

Chemical used for sedimentation and decantation​

Answer 1

Answer:

Adding chemical or natural coagulants to the water can quicken the sedimentation process. Aluminium sulphate, polyaluminium chloride (also known as PAC or liquid alum) and ferric sulphate are three common types of chemicals used for coagulation.

The process of deriving vinegar also requires decantation to remove fats and biomolecular antioxidants from the raw substance. Plasma can be separated from blood through decantation by using a centrifuge. Mercury is disposed of in water bodies during mining, turning the water unfit and toxic.
