74Metal part coating金属へのコーティング事例Content： A magical device is proposed to recover the floating A magical device is proposed to recover the floating media, such media, such as floating oil spilled from tanker, carbon-scum as floating oil spilled from tanker, carbon-scum accumulated inaccumulated in water-soluble coolant tank, microplastic water-solublecoolant tank, microplastic mixed with seawater and mixed with seawater and river water.river water.Common filer has been often clogged while the micro-sludges are Common filer has been often clogged while the micro-passing through the porous media. This means that it is difficult to sludges are passing through the porous media. This means recover the micro-sludges using the filter.that it is difficult to recover the micro-sludges using the filter.The recovery of floating oil and microplastics from sea and river The recovery of floating oil and microplastics from sea and water is also difficult, because they are tended to move as the liquid river water is also difficult, because they are tended to move moves not as the solids, like a goldfish in the “goldfish scooping; as the liquid moves not as the solids, like a goldfish in the KingyoSukui”.“goldfish scooping; Kingyo Sukui”.Well then, what should we do ? Well then, what should we do ? Appealing point：Collecting micro-sludge on the surface of porous media while the liquid containing micro-sludge is flowing on porous media.Example１１Recovery of floating oil from waterExample2Recovery of carbon-scum from water-soluble coolantRoom temperature atomic layer depositionPlease put your photograph.
