Removal of oils from water surfaces with modified Linden sawdust

Abstract

The paper investigated the possibility of using modified woodworking waste to remove heavy oil products from the water surface by sorption. Sawdust of a heart-shaped linden tree (Tília cordáta) was used as sorption materials and used diesel engine oil was used as a sorbate. In order to improve the sorption capacity and increase the sorption capacity of wood waste, they were treated with ultrasound at a frequency of 35000 Hz in an aqueous medium for 4 hours. The physical and mechanical characteristics of modified sawdust have been determined: bulk density, ash content, buoyancy. Experiments on modeling engine oil spills on the water surface have shown that linden sawdust, subjected to ultrasonic action, are effective sorption materials in relation to used diesel engine oil. The degree of water purification under static adsorption conditions reaches 99%.
