Milk centrifuge for wvo and black diesel
 

Could a milk separator work for filtering fuel instead of a special biodiesel centrifuge? Even if it requires a few modifications (probably does) that still would do great cost savings, buying a used oil centrifuge locally is basically impossible. Milk ones on the other hand are widely available.

I don't know but looked into i enough to find this:

Do you want to clarify (remove solid particles) or separate (i.e., water)?

I guess clarifying would be the better choice? Proper waste oil centrifuges deal with the water too, but maybe I could just boil it away.

Generically:

I worked on these things for years. Yeah it would likely work. I would be surprised if it didn't.
Yes you would want a clarifier.

As oil floats on water, couldn't you just have a tap at the bottom of a settling container?
Preferably a container that conical at the bottom.
