Filter Modified with Hydrophilic and Oleophobic Coating for Efficient and Affordable Oil/Water Separation

To mitigate the damage of oil spills, a filter modified with hydrophilic and oleophobic coating is proposed for affordable efficient separation recovery from water. The sol–gel method was chosen to produce colloidal suspension titanium dioxide particles its ease production versatility in application many different substrates, including paper cloth fabric. After immersing substrates into titanium-containing solution, three techniques were applied increase dioxide—microwave-assisted, refrigeration, ultra-sonication. Contact angle tests done investigate change filter’s oleophobicity. present on surface amorphous, but all treatment methods showed an improvement All treated filters improved filtration performance by up eighty percent. isolated motor mixture while allowing water pass through. coated also displayed photocatalytic activity degrading methylene blue when exposed sunlight, demonstrating self-cleaning ability. For real-world applications, can be supported stainless mesh enhanced strength durability. While being dragged through water, collects oil, via gravity.
