| Abstract |
| For optoelectronic equipment (transformer) to last a long time, insulating oils are essential. The lifespan of a transformer is impacted by the aging and degradation process of insulating oils under specific operation conditions, such as high temperatures, arcing, sparking, or electric faults, which leads to deterioration of its oil. Since insulating oils are costly, regeneration is preferable to replacement. In addition to eliminating dissolved gases and furanic compounds, as well as slags produced in transformer oil during operation, the oil must be reclaimed. The most widely used materials in this manner are aluminum oxides and silicates. In this work, aluminum oxides and silicates are obtained from the sludge produced from drinking water treatment. When water is treated with aluminum sulfate (alum), the produced sludge is enriched with silicon, aluminum oxides, and traces of Fe, Ca, Mg, Na, and K oxides. The produced sludges were thoroughly examined both quantitatively and qualitatively using the dual-pulse laser spectroscopic technique (DLIPS). The performance of the extracted sludges is attributed to the large surface area. In addition, the sensitive DLIPS technique reveals its capability to record elements such as Si, Al, Fe, Ca, Mg, Na, K, and O, which were validated by ICP-OES and EDX systems. This sludge was used as an adsorbent material to improve the properties of the transformer oil. |
