You can use air from glad hand but a separate air compressor Pto driven is much better.....

Like a septic truck that vacuums up the liquid to self load ....

 

Vacuum trailers are often used to haul things like grease trap and grit trap waste or oilfield produced water, but they can haul hazmat and hazardous waste. I have used one to transport oil-based drilling mud, which was Class 3 flammable liquid.

 

More the clean up and clean out side. though most vacuum trailers are built to SPEC for haz mat use...

regarding air compressors, Emglo was one brand, Quincy was another..

Matlack had 4 cyl [Ross] engine compressors on the Macks and a PTO driven pump. Worked OK but replacing the compressor was complicated as they went back to only one supplier

Compressors and pumps [and DB Blowers] each have their own specific RPM range so the PTO or Hydraulic drive need to be matched to the application. Pumps usually run slower than compressors. DB Blowers need to scream so they turn faster than both...

 

Air compressor on passenger side, unit bolts to frame and has a driveshaft that runs underneath to the transmission. Pump on drivers side. Same thing.

You run a hose to the trailer flip a switch on the dash and voila blow air into the tank. Pressure pushes the crap out.

Alternative is to suck it out with the pump, in which case you vent the tank so air can come in to offset the product leaving.

Flammables typically have an enclosed system where instead of cracking a vent valve you have a vapor line hose. Occasionally you’ll air off a flammable with nitrogen instead of compressed air.

But that’s the general gist of how it goes, aside from the valve details.
