Post by: Rotary-Motion on November 04, 2012, 07:48:16 PM
hi all

had an odd one today after 4 years filtering, went to the crud container to tip some more in and the thing was blown up like a balloon! i took the top off and it blew out some air. i looked into the top and saw lots of bubbling like i was bioling it or something the whole amount was bubbling...

Was there water in there?  I've seen oil like that before, which has been rained into.  Would worry about filtering for fuel but it makes fine bio.

yeah prolly alot of water suspended as its me crud from bed sheets... etc...

you cant see it there but the bubbles were quite big bubbling up through looked like a couldron lol...

picked up alot of rained in barrels lately idiots dont replace lids (and i paid for rain water too)

you can just see the poppadoms floating in there.

also one contact uselly leaves half lemons/grapes/ and all manner of pims making parafanailier inthere barrels smells quite sweet...

Indian oils are usually quite rank... one place I used to collect from the oil was bright orange and I'd have to drive back with the window down and my head out of it, even when raining in winter.  Horrid stuff!

Did the oil get warm when it was bubbling like that? The leaves and cr@p decomposing would produce bubbles, but thats a fair reaction going on, I'd say. I was putting animal muck and leaf mulch into a drum to make fertiliser for tomatoes over summer, and it never bubbled.

Give it to Vince and we can drink it at next years BBB, but you get to try it first.

no, its stored in a cool place under a leanto roof so no sun on it either, also no leaves in there just poppadoms...

shouldnt your mulch create heat? we used to cover our crap on the farm with tarpaulins (tea bags and all in there) mostly straw and animal poop, and in winter could warm ya hands on it steaming away, (must keep turning over introduce oxygen to mound) once a day or something...

my 1 indian i pickup from once in a blue moon is 20/30 ltrs is crystal clear but loaded with poppadom crisps... but still alot of fat in it, this one lot has always confused me as no layering in the oil as clear see through but filtering gets it out...

wonder if its that GHEE stuff they cook with?

There was on news article about a farmer that ran pipes through his manure mound, to keep his house warm.

Just had a google and it seems the idea is not new, in fact this french farmer took it further with Methane collection as well:

kool nice idea use the natural resources...

when we finished raping the world and destroying it of its own resources, we will all have to do this and live in biospheres with allotments for food...

I have had this happening in cubies that have some of the cleaning fluid in them that places use to clean out the fryers.

For sure. I've seen an iron bar pushed into a muck heap, that was almost to hot to touch after a week or so. I was just wondering if RMs oil was getting warm from some kind of chemical reaction. I guess in smaller quantitys the heat is not significant.
