We offer effective method of biological purification of water surface from oil spill of any size. In the surface of oil film as adsorbent (nozzle) is placed light, porous, cheap, little sized scraps of matter, with immobile microorganisms – oil destroyers. The oil penetrates into all pores of the adsorbent (nozzle) and becomes the catch for microorganisms. When the oil adhered to the adsorbent is completely destroyed it is again penetrated by oil. Each part of the nozzle functions as a small factory – as a result we have continuous oil destruction.

Already from the third day from the experiment commencement it was observed oil film cell-decision and then almost its full utilization by microorganisms. By helping of aviation, nozzle with immobile microorganisms could be sprayed the oil spill of any size. For the purification of reservoir surface, such as rivers, lakes, seas and oceans from oil film we need approximately one month, the adsorbent (nozzle) with immobile selection microorganisms may be collected and then it can be used again for several tens of years.
