Filtration: Removes solid particles using mechanical filters.
Centrifugation: Separates contaminants based on density differences through high-speed spinning.
Vacuum Evaporation: Eliminates water and volatile impurities under reduced pressure.
Ultrafiltration: Uses semi-permeable membranes to remove emulsified oils and fine particles.
Chemical Treatments: Applies coagulants or demulsifiers to separate contaminants.
Bioremediation: Utilizes microorganisms to break down organic contaminants.
