Evaporating Ultrasonic Waste Water

To pump out 2 VMC's I was quoted approx $1200

Or if I pump into 55's, then $275 per 55 to haul away.

Coolants going bad, so need to change out soon. $1200 made my sphincter tighten a bit. There again, nothing as compared to fines if I were dump the coolant.

------------------------------------

Plan B is to pump into 55's add Epsom salts which allegedly 'cracks' the water/soluble into oil and grey water. I guess the question is whether I can legally dispose of the grey water myself.

Ultimately I think I'll get the 55's hauled as is, don't want to draw too much attention to my self. Might have the city or FD come by for the first time in 15 years.

Buy yourself a hobby farm out in the boonies ...then you can irrigate a hundred acres with a watered down mix of anything bar heavy metals.........if the soil is heavily mineralized ,you may even be able to do that........This not environmental ly bad,as there are a million bacteria and fungi that eat whatever is in your waste liquid,provided its spread thinly enough.

All those worried about oil forming at the surface, you can avoid this by setting up an overflow weir. In a 2 chamber system so long as the lower chamber has more volume than the tramp oil, and so long as it can separate, the top chamber surface will remain clean. If a cheap pond pump isn’t destroyed by your coolant there’s an easy solution and the flow rate can be extremely low.

As for processing waste vs using it for a secondary purpose, our waste guy was big on the latter. He regularly reminded me for small quantities that evaporating solvents was forbidden waste processing. On the other hand, if I needed to soak an engineering sample in an open solvent container overnight and happened to leave it in a fume hood that was perfectly acceptable. Somehow there was never any left in the morning.
We also had some sort of device that seemed a bit like an RO filter, but not quite, that would pull oil out of our waste water and let us dispose of the water portion down the drain. We were a big enough place that the county environmental person did a reasonable audit monthly and we always passed.
