METHOD OF WATER SURFACE PURIFICATION FROM OIL PRODUCTS Russian patent published in 2008 - IPC B63B35/32 E02B15/04 

FIELD: purification.

SUBSTANCE: method of water surface purification from oil products lies in directing layer of polluted outside water into inlet tank and in intake of oil products into hermetically sealable at least one chamber. Before beginning purification of water surface outside water is poured into chambers and hermetically sealed. After that inlet tank is filled with polluted water in such way that its layer is higher than level of lower holes of chambers, after that they are opened and water is poured out, until water columns are balanced in each chamber by means of outside atmospheric pressure taking into account dependence of their height on chamber volume. Oil products from polluted water go up and displace heavier water from chambers. After complete replacement of chambers content with oil products, lower holes of chambers are closed, disconnected from inlet tank and transported to place of pollutants discharge.

EFFECT: increase of productivity of technological process of water surface purification from oil products.
