Titrated Acid water wash.

So if this is correct, and I suspect it is, demething the bio before washing could reduce the amount of washes needed.

How much methanol would you expect from the bio alone? Would the time and effort put in be outweighed by the volume recovered. Bare in mind the reduced methanol now being used in two stage no tit methods.... would it be worthwhile?

I'm absolutely sure that a meth test on consequtive washes will show an incremental reduction everytime.

That would make sense, but it would be good to see if the soaps drop in a fairly linea way, if not is there a meth % that sees an increase in the amount of soaps released?  It would be an elegant answer to what can be seen from time to time, ie 50/50 clear on one wash, with the next wash producing a more cloudy 50/50.  It's not too important as going through HW shavings seems to do the job, but it's nice to be able to explain observations.

Demething does reduce water washing, but with new ways of pump washing with 2 or 3 buckets of water, is it worthwhile?

Steve, tried this I think prior to water washing?? I can't remember what he said about it.

It may not be worthwhile when doing non tit (I'm down to 16% meths now), but for others that are still titrating there may be some gains.

Agreed

What are your conclusions about water washing?

The reason I was going to demeth before washing was simply because I was experiencing methanol fumes with every wash and even when the wash water was clear I got meth fumes when drying !

The next batch I made was with Acetone and it settled so quickly to a clear 50/50 I found it was not worth washing.

I'm only using 10 - 11% virgin + ASM + reclaimed.

And yes I think demething IS worth the time and effort, less than 30p to get 4-5ltr of methanol back.

Now you're potentially on board with us strange water washing types.  What can you do to shorten drying times in a sealed system (simplest possible method) to at least as comparable with a spray bar ring?

I partially dried the wet bio using the condenser AND squirrel and finished off in the settling tank with the Bubbler.

Nothing new then.

How long did this take?  The spray bar / ring thing dries in less than an hour.  In a sealed system it'd be good to have something comparable!

Exactly the same system as most demeth with will work for drying mate.

i would just like to add i just read all this thread, i got nothing to offer, but all the same a very interesting read !

ok im done

Cool!  On the new system then!
