How do Coalescing Filters remove water from oil?

Coalescing filters basically operate on the same principle as water separability - make small water droplets connect and form large droplets which fall to the bottom of the reservoir faster.
With coalescing filters, we simply use an accelerator. For mechanical coalesces, this means a filter media that is oil-wet and prevents water from getting through, for electrostatics its about changing the shape and charge of water such that the droplets attract one another.
This is a really important technology for large hydraulic, turbine, compressor oil systems.

My dad was an old timer aviator. He used to filter his fuel with suede cloth to remove water. It worked wonderfully for 2 stroke premixed fuel/oil. You could see droplets of water on it at the end, possibly because of the oil. Then it doesn't work for cars nowadays, because the ethanol added makes the water diluted in alcohol, pass throught the suede cloth... You need to know some polarity, coalescense and solvability stuff.

Fantastic explanation. Thank you for sharing.

Thank you for the great explanation.

Thank you very much for this lecture. Indeed, you are a doctor in this field. But I have a question, please, dear. What is the alternative solvent for sulfur acid in the setting of the bitumen?

[@colecarlson335]

Why do Glide lubricating Oils and Diesel Fuel Gel . Is it Because the additives / or Cold Temperatures . Is it possible the Low pour point was C°/F° was exceedingly To Low . Is there any chance to additives of anti Gelling agents applied .

Does coalescing work with water emulsified oil also?

so wont the water particles be attracted to the metal plates which will be inducing charges

[@educationalporpoises9592]

water is polar, the metal plates individually are not. So the closer a water molecule's localized positive side of the dipole is to a negative plate, so too is water's localized negative side of the dipole which decreases water's attractedness to the plate, even if the positive side is slightly closer to the negative plate. While in solution, there are other, much more local and smaller water dipoles to be attracted to one another, so the positive and negative charges of each individual water molecule can be satisfied in those attractions. Does that make sense?
