So, I got this PM this morning, and I figgered I may as well answer this out front:
Well, if you saw a thread that I had last fall about the tote with the spigot issues?
That was a tote that had old coolant and waste water/oil from the skimmer on the parts worsher.
By letting that sit around a while - it mostly separates - which I'm sure that your 55 gal drums have as well.
Every so many years, in the winter I will crank up the heater in my batch type worsher (for like tranny cases and whatnot? - we don't normally runs production parts through it. Mostly for worshing up our parts trays.) And then I start dumping the waste water back in there. The heat is not wasted as it is winter, and the skimmer on that worsher pulls the oils out as you go. You get a lot of colored water that doesn't have much oil content usually by this point. But it can smell the place up for a bit.
As you evap off the old water, any oils that were in suspension have to go somewhere, and so they float to the top. If you are not able to skim them off, you just sealed your evap surface. The commercial evaporators that I have seen at the trade shows never have any skimmers, so I guess they are only good for mop water? Certainly not machine shop fluids.
Now this will still leave me with the oils when done, and at that point (there are a few buckets of really nasty stuff tho too) but when I get a good job in an Acme sometime (seem evasive these days) then I will likely just pour it in there and it will clean it right up - if it's a hot running job anyway. Otherwise - option B is that I can always just give the oils (maybe not the real nasty stuff) to a chum with a waste oil furnace.
As for the real nasty stuff (that doesn't like to skim well) I might just pour it over a cardboard and waste paper fire before and after the crops go in / come off.
... and then recharge the worsher when done eh?
One other trick that I use, as much of the stuff that I deal with is already skimmed oil that have water that pulled out with it as well, is that I have a 15 (?) gallon drum with the top off of it. I dump it in there, and I have a pump in the bottom and a skimmer on top. I try to keep the water level below the reach of the skimmer and that yields me a pretty good start to having oil and water, and not drums of mixed all over.
It would be swell to one day land a nice coolant recycle machine with a centrifuge and all, but I'm not sure that I would ever be able to justify that, but it's a goal...
So - that's what I have been dooing...

Xxxx said:Ox, Good thread.
I wish I had seen this a month ago. We are in the process of switching over to Blaser. What are you doing with your old coolant ? We used Rustlick WS 5050 for the past 25 years, water based. I have 16 55gal drums of old coolant and I'm having trouble getting rid of it.
I want to build something to boil it off or buy something. I'll probably save money long run if we can build something efficient. I got quoted north of $2500.00 to take it away and a four week wait, then the guy backed out of the job so I'm back to square one and pissed off.
What do you do ?
Thanks, Xxx
