Can you use a Vortex unit with a septic tank?

Do you think taking the waster outlet from Marsh septic tank into a Vortex unit would actually work. I was wondering if the lack of solid material would be a problem in the Vortex unit. Cheers

Why both? So now you have two units to pump out. Would you not just by-pass the septic tank?
