Disposal regeneration and recycling

25 November, 2014

from the filtration process should be disposed of through a specialised contractor. Most water glycol fluids are readily biodegradable and are therefore amenable to disposal through the waste water treatment plant. As stated earlier, this would have to be in agreement with the local utility. The fluid can be supplied to the waste water treatment plant either by tanker or through the sewer network. Heavy metals and other contaminants would have to be removed from the waste fluid (e.g., by filtration) prior to disposal. HFC fluids should never be discharged to a watercourse as this could cause a major pollution incident due to the high biological oxygen demand. This is also true for environmentally acceptable fluids (HETG, HEES and HEPG). Containers Medium - large containers, such as 200-litre drums or IBCs (intermediate bulk containers), should be emptied and returned to the supplier or a specialist reconditioner. It is important that the container still retains its original label or markings to identify the previous contents.
