The futility of 1u filtering

[Tony]

The bio was very foamy pumping into a drum - turns out I'd dipped the pickup into the glyc at the bottom of the settle drum.



See that black layer at the bottom? This went straight through a 1u filter without any issues at all.

Perhaps useful for keeping grit and waxes out of the final fuel, but definitely not soap or glyc!

[Manfred]

That explains why I've seen fallout in my stood cubbies then. At least it won't block the filter but not good if it settles in the bottom of the tank.

I know you like the 20 ltr drums for cold weather acclimatisation, but a bigger storage tank, floating pickup and a dispensing hose would prevent it happening.

That or may the way to go is centrifuging ... where's Nathan!

[Julian]

No second thoughts that's a lot of glycerin to be dropping out of finished bio.  How about water washing?

Is that why my first wash water is always brown

Not a commentary on fuel finishing, just pre-tank filtration.

The 25l drums I have to use to carry the 35m from the outbuilding to the car

The level of brownness could well be due to glyc carry over. I'm pretty careful with mine but the first water wash is a dark beige due to soap migration.

A good looking bitch was she?

Isn't that illegal though?

Paddy has always maintained that to get the bio to pass all the regs you need to allow it to settle for 72 hours before moving on to washing / settling

I can undertstand this with dry washing, but with water washing surely the water will remove anything that would settle anyway.
