文摘
- •
Resin bonded filter media were prepared with in situ generated surface roughness.
- •
Media wettability was fine-tuned by resin solidification control for emulsification.
- •
Media were able to coalesce 3 surfactant-stabilized oil-in-water emulsions.
- •
Separation was surfactant type dependent due to differed adsorption intensity.
- •
Ethanol was identified as an alternative solvent to IPA for resin emulsification.
