Abstract: The present disclosure relates to a fence having a hydrophilic material, and according to an embodiment of the present disclosure, there is an effect in collecting oil or hazardous & noxious substances quickly and efficiently while minimizing the pressure caused by water, by forming the fence from a material that allows water to penetrate while disallowing oil to penetrate.Additionally, there is an effect in preventing oil spill phenomena caused by damage or unbalance of the fence by reducing the water pressure applied to the fence due to water penetration even when a strong water pressure acts on the fence, for example, strong tidal currents occur and the fence is towed at high speeds to collect oil.

Abstract: Provided are spilled oil collecting apparatus and method. The spilled oil collecting apparatus includes: a filter portion made of a porous substrate with hydrophilicity and having an open upper portion so as to collect oil; a frame portion provided at an upper end of the filter portion to support the filter portion; and a handle portion connected to the frame portion. According to the spilled oil collecting apparatus and method, it is possible to collect, separate, and store simultaneously spilled oil spilled from rivers or seas by using a porous substrate having hydrophilicity and optimize immediate collection of spilled oil by maximizing oil collection efficiency and minimizing labour force in an oil collecting process.
