Condensate from Air Compressors
Condensate from Air Compressors
(OP)
All,
Regarding air compressors where the condensate (water/oil mixture) is collected in a knock out drum just after the compressor.
My question is can anyone confirm the ppm of oil in the water/oil mixture that is allowed to be piped to the waste water treatment facility?

RE: Condensate from Air Compressors
I think that the oil-in-air content going *to* the waste water treatment facility probably doesn't have a hard and fast limit, but the oil-in-water content coming *from* the waste water treatment facility will be more of a concern. It depends what you are doing with the water, i.e., where is it going? That would be a Regulatory matter.
I think that you need a bit more detail in the question; for eample, what is the capability / limitation in the water treating side?

Oil is relatively easy to trap out of water flow anyway using simple gravity traps, but adds a maintenance item. Service stations use them for forecourt drains.

If it's a publicly owned treatment works (POTW), most sewer regs limit the amount of free product you can discharge to zero. You are expected to have oil/water separators on anything that can discharge any quantity of mineral oil and grease to the drains.
