Hauling sludge and the smell

talk about smell....I did 2months in the 80s hauling solid human sludge in tippers dug out of an old quarry where it had been dumped for 20yrs( the ground water level was rising so it was to be dug out and taken 50miles to a lined landfill .....dear god on our first run the lights turned to red in a small town we ran through ,people were throwing up in the street ..we used a can of air freshener in the cab every run! anyway by the time we (4 truck convoy) came back through town we had a police escort, for the rest of the contract going through town john law was waiting to rush us through . Not once were we stopped by john law /checked out. by the way this was back in the auld country(Scotland ) at my first truck job. jimmy

I've been hauling sludge for the last 3.5 years. As far as I've experienced, there is no way to stop it from smelling completely. Then again, I dont notice it anymore lol

 

This sounds a little more explanatory!!

I ran a honey wagon as a teenager,
If you don't drain the exhaust trap regularly, and clean it good every so often, I'mean unhook the hose, degreaser and steam jenny right down it's throat!!
It will dribble all over, and make a mess, like a drip droit would do!!

Depending on your tank setup, condition, and valving? and haul distance?
You could pull a vacuum on the tank after you blow your load...
Sorta Precharge it for pickup!!
If it'll hold vacuum till you go to load it should greatly reduce your gravity load time!! still won't get a full load but the first half will pull in....

Also Vacum or dry pump loading is so much neater and cleaner than product pump loading!! you can suck the lines dry and not spill any when you disconnect.

On another note,
Have heard of, but never used or seen an exhaust filter bag for odor??
If memory serves me right it was for the top hatch on a dry bulk tanker???
No Idea if it's true or worked or made in other "shapes"!! be worth a search.
