My big score is not so big anymore [img]/ubbthreads/images/graemlins/blush.gif[/img]
My resteraunt produced over 100 gallons of "fluid" in the tank I put out in a week.
I got some of it the other day, and let it sit in a 200 gallon tank. I put in about 80 gallons. I just drained the water off the bottom, and am down to about 25 gallons of oil. [img]/ubbthreads/images/graemlins/frown.gif[/img]
We haven't had any rain since I put the tank out. How could they get that much water in the tank? [img]/ubbthreads/images/graemlins/shrug.gif[/img]
Check the pH. If you still have that water you can use pH paper as it is mostly water. If it is mostly oil the pH paper doesn't work due to the absence of water. I'd be fearful that they have been rinsing out their fryers and dumping the water with the oil. Not good. There is a significant possibility that this water will have a really high pH due to the cleaners.
Kitchen cleaners are along the lines of Castrol Super Clean... but even more alkaline. And this can really eat up your injectors even if you have stripped out most of the water from the oil. The traces of highly alkaline water in the oil can be catastrophic to injectors.
Good used oil will be slightly on the acid side and I doubt ever alkaline due to the Free Fatty Acids (FFA's).

i have found they don't use a cleaner just plain hot water, and they mix this into the waste oil as long as you get the oil off the top and don't mess with the water you should be ok.
Toddt: I don't get the deal with the PH levels. Nobody should be processing oil with any quanity of water in it anyway as the conversion to biod will fail or at the very least not produce good biod as the methanol will be diluted by the water. There are everal ways to drain the water including heat, settleing etc. But once the water is gone the PH of the oil should not matter...once the convsersion to biod takes place he should be washing the biod anyway with "good" water to get rid of all the soaps & glycerine castrol super clean or whatever. If not it ain't washed enough! . At that point the PH should be the same as whatever rinse water he is using.
I test the wash water...once it is close to my tap water I know I have washed enough.
I'm not saying he didn' get some bad oil but the water can be removed...I heated 35 gallons & ended up with 12 good gallons of oil. Talk to the resturant owner...most likely they will stop dumping water with it if you ask. If not move on....

Get some pH paper at the spa or pool store or even the hardware store.
Don't accept any oil that has any quantity of water added to it. It is expected to find a small amount of water and crispy crumbs at the bottom of the barrel. Ask them to only pour the oil from the fryer into your barrel, but none of the rinse water. Tell them that adding water ruins your fuel process and you can't use that stuff.
The truth is that once a large quanity of water is mixed in (1-2 gallons), it takes a lot longer to settle the water back out and also adds to the byproduct reactions in making bio-diesel.
Good luck, Hugh

Sorry, my mistake. The damage I was talking about was a guy doing heated WVO in a dual tank setup rather than biodiesel. Yes, the biodiesel blending and washing should take care of any water and yes... any caustic cleaner would totally screw up your initial titration.
Does anybody know if alky contaminated oil could be used? I'd suspect it would have to be washed and de-watered as WVO before even going to the biodiesel blending. And then, with the alky components washed out, the titrations shouldn't be much over the base amount. Sound reasonable?
Boy... only 1/3 oil in the water. That hurts.
