What is the effect of surface tension on oil-water separation?
Thread Content
I know that oil-water separation is greatly influenced by factors such as residence time, the density difference between oil and water, and viscosity! Does anyone know how surface tension affects the separation of oil and water? The surface tension of oil is much lower than that of water. To improve the separation effect, we add a solvent to water – does this increase or decrease the surface tension of water? Please give an example! !
If separated, it should increase the surface tension of water :$
Just read \"Adsorption, Specific Surface Area, and Porosity\" and you’ll know; there’s no need to explain it to you

It depends on your separation principle; either increasing or decreasing the surface tension of water will work
1# hy-hg2005: The greater the surface tension, the higher the surface energy; as a result, the suspended liquid droplets tend to aggregate into larger droplets in order to reduce their specific surface area. Therefore, increasing surface tension helps with separation.
Increasing surface tension helps with separation
I would also like to ask: when carrying out oil-water separation, does temperature increase or decrease the density difference between oil and water? Are there any professional and detailed explanations available?
