| Summary: | The existing technology for separating oil in water (OIW) can bring harm to the
environment, particularly to marine life. A new environmentally friendly technique has been
proposed, involving the use of milliscale air bubbles. This study was conducted to determine
the suitable retention time for injecting the milliscale air bubbles into the OIW. The
significance of this study lies in its ability to separate OIW through a procedure that is
environmentally safe and does not impact the ecosystem or marine life. The method used in the
study involved mixing palm oil with water on a volumetric hydraulic bench. Retention times of
5 minutes, 15 minutes, 30 minutes, and 60 minutes were used in the study. The results
indicated that separating oil in water required a substantial amount of time when utilizing
milliscale air bubbles. In this study, a 60-minute retention time exhibited a significant number
of separations, producing 512 bubbles compared to 44 bubbles generated in 5 minutes for 200
mL of oil. The longer the retention time, the more bubbles were produced. Overall, milliscale
bubbles can effectively be used for the separation of oil in water |
