Yes, I saw this a few weeks back. Kept meaning to post it here.
Fortunately there are others on the list more on the ball than me.
Thanks, Keith.
There were a one or two things that bothered me about the talk, though.
Firstly, from my recollection he makes no mention of CAFOs. None.

Seriously, tho, what you're doing is great -- FFAs are basically the
final effluent you
have to deal with after neutralizing everything else. They're fairly
strong herbicides,
so you really don't want to just toss 'em in the compost with the
aqueous phase.
Ken, do you
Where can I find info on continuous process for BD?
Thanks

After settling my glycerin, I decided to wash and neutraliza it. I first used
vinegar, but noticed the pH level whent down very slowly, and I was rather
diluting the glyc with too much water from the vinegar acetic acid solution.
So I reached for the HCl 35% (muriatic) acid.
pH started going

Interesting!
Does it always form? And is heating and neutralizaing the usual way of
getting to it?
Thanks

FFAs ionize to some extent (i.e., they form soap) down to
about pH 4.5, according to my expts. If you start with a collected
glycerine phase at around pH 10, and your aim is to get it to
