love this page!

very imformative

do you think waste oil filtering system on vegetable oil pages link would also be benifcial in biodiesel pages link?

[Julian]

Don't know.  I filter my oil for bio through home made landscaping fabric sock filters, and I've been accused of going over the top!

Filtering oil for bio to the same extent as use for straight veg may be going too far.

It might make another bio page though ... different ways people prepare oil for bio production.

yes see what you mean, not tottally 100% on how bio peeps work there systems

yes leave as is, see how it pans out...

Nothing as sophisticated as that - oil is only very coarse filtered for processing and the final product only some people bother to filter at all (usually a single 10" filter).

Don't really need to filter finely for biodeiesel, you only needs to catch anything that will clog the pump, mine is an old fire guard screen, many use a kitchen seive or wire basket from waste/pedal bin.

Most of the reason for filtering to that extent was ignorance when I first started making bio.  But latterly I recon it's not a bad thing as the socks are easer to clean out than the barrel and by catching every small food particle I now recon you are removing thousands of potential little water containers.

Each to their own I guess, but I think it will make a great page with all the different methods people use.

the better the filtering has got to make a better batch...

i hear ya on the water particles, i just scooped out 20ltrs of mush, what the cold weather has made, most of it being WATER! trying to freeze... not mainly fats, its the suspended water is causing me hassles....

[Tony]

Shouldn't be too much of a problem if the oil is settled after course filtering and all the little bits settle to the bottom.  In that respect, that's good biodiesel related advice that could be taken from the filtration pages.
