Oil Free Compressed Air Condensate Disposal

No idea of Indian Law, but there is nothing in the water produced that is not already in the air that you are breathing, so disposal should not be a problem.

You are right there is nothing in the air already that we breath that would not be in the water condensate. Then again we do not heat the air we breath to the high temperature of compression. Then cool it to a dew point of -40°F. Some of the contaminates can be concentrated in this condensate. We also do not know what the air in the environment holds. With out test on the condensate we do not know what hazards it holds.

To Nayek most compressor manufactures produce a filter that will filter the water. They are excepted by agencies in the USA for disposal of condensate down a sanitary drain. I do not know if this would meet India's standards or not.

Condensate water is not a bad water. In fact you can use it for several applications and help in water conservation in small way. The easiest I can suggest is to use it as mke-up water for cooling system (gas coolers or oil coolers) or washing.

You would be putting concentrated gunk into a clean water system. Often these compressors are not in the cleanest of areas.

As of 3 years back there were no rules on this subject - at least none any inspector had ever heard of.

Let it go to the drain.
