FIELD: environment control. SUBSTANCE: this is intended for protection of rivers and their benches from contamination with oil. According to method, oil spread over surface of running water is concentrated within limits of narrow strip along fairway of river and directed into coastal double-chamber settler. This is achieved by means of stream directing devices which divide water flow in depth for creating lateral circulation of water which is counteractive to natural circulation. Chambers of aforesaid settler are subsequently connected by bottom water outflow passage. Water separated from oil impurities is discharged through bottom outflow passage back to water source. Bottom threshold is provided at inlet to settler to protect it from silting. Application of aforesaid method allows for protection of water sources from oil fouling in economical, efficient and easy way. EFFECT: higher efficiency. 1 cl, 1 dwg
