[Terrapreta] Terrapreta Digest, Vol 16, Issue 25

Typically, these educators are steam powered. The specific volume of steam
reduces drastically upon condensation. Air would simply explosively disrupt
the soil.

 

A progressing cavity pump with a thick, hard-chromed rotor and a nitrile
stator would pump this slurry nicely, I think. Or a recessed-impeller
centrifugal pump, at lower head pressures.  There are many synergistic
coatings that are more resistant to abrasion than titanium.

Hi Jeff,

 

Yes, eductors, otherwise known as venturi ejectors can be used to move
solids entrained in fluids or even dry solids.

I haven't been fallowing this so I don't know if this will provide the
proper head but I've ised an air lift to pump some nasty stuff.
