Ok, so at the moment I'm having a go at running a batch of "wash" through my "water purifier" (a still in everything but name).
I haven't measured the % abv of the wash or the resulting distillate (yet), but out of curiosity, I dropped both my wine hydrometer and my spirits hydrometer into some of the "waste" (for info, the purifier instructions say about retaining it i.e. the waste, if you want to experiment further). Anyway, it's still hot, and I'm presuming that I'm supposed to wait until it's cool, but rather strangely, the "waste" was giving a reading of 20% abv on the spirits hydrometer and 0.980 on the wine hydrometer.
The only thing I can presume is that gravity reading is indeed affected by temperature of the liquid being measured (any chemistry grad's out there)?
It also occurred to me as to how long I might need to run the purifier, to strip all the alcohol out of the wash ? even though the "waste" is, apparently, very good to use as "screen wash" for my truck/car etc. From the smell of it, it still contains alcohol, again, presumably in great enough quantity, to be used as screen wash, and I'm also guessing that the addition of some cheap detergent of some sort, would improve it for that purpose.
I'm sure I'm running the purifier properly i.e. 4 litres at a time (though I'm gonna have another look at the instructions after I've finished posting this).
If anyone can shed any light on this, I'd be very grateful.
regards
