PCB removal from transformer oil can be achieved through several methods such as adsorption, chemical treatment, or advanced filtration techniques. The most effective method often involves using activated carbon or specialty adsorbents that can effectively bind to PCBs, allowing for the separation of contaminants from the oil. The oil is typically subjected to a combination of vacuum dehydration and filtration to remove water and particulates simultaneously, further ensuring a clean end product. In some cases, chemical agents may be added to facilitate the breakdown of PCBs into less harmful substances, although this approach requires careful handling and adherence to environmental regulations. After treatment, thorough testing is essential to confirm PCB levels have dropped to acceptable limits, as improper handling of PCB removal from transformer oil can pose significant environmental risks.
