Safely treat your condensate before disposal into storm-water drains to avoid damaging contamination.
Condensate is an unavoidable result of air compression. It is a chemically aggressive fluid that mainly consists of water, but also contains oil and dirt particles.
Oil carryover is unavoidable if you have compressors that use oil in the compression chamber.
The lubricant will mix with the condensation and create an oily water that must be properly handled to avoid violating environmental regulations.
Just one litre of used oil can contaminate up to one million litres of fresh water.
This is the reason that environmental regulations strictly prohibit the discharge of oily wastes and chemicals, including the condensate drained from a compressed air system.
Compressed air condensate must be treated in accordance with water resource legislation to achieve prescribed safety levels before it can be disposed of in the waste water system.
No! Not unless it has been pre-treated, and the oil has been removed.
By installing a water/oil separator, the oil will be removed leaving the water at a safe level for disposal in the storm-water system.
This will vary depending on how much condensate you have in your compressed air system but it should be at least every 12 months regardless of compressor operating hours. If your factory is operating 24/7, the oil/water separator should be serviced every 4000 hours.
Water quality testing should be performed at least monthly to ensure the oil is being removed to a safe level. If a high oil concentration is reached before the normal service interval, the filter cartridges should be changed.
