Having an issue with our coolant/ waste oil from our 3 VMC which is baffling me.
For the past 2 years the lab reports for our waste oil and coolant disposal have come back with SUPER high levels of Cl which means they have to take the stuff in sealed drums and cannot suck it out with a vac truck. Its way more of a hassle with the drums and more expensive too.
Allowable levels are <1000 ppm, 2 years ago we were over 13000 and last month they measured over 9000. They say anything over 100 can cause corrosion on the machine and parts, which we do see.
I don’t understand where the chlorine (or chloride) is coming from. We started completely fresh two years ago so I don’t think there is any way the chlorine in the water has built up that much.
We use Trim E206 coolant, and Mobil Vactra way oil, occasionally spray things down with WD-40 but that’s really it.
Anybody else had similar issues? Trying to figure out what is causing it so hopefully we can make a change and keep the levels down.
