| A METHOD OF OIL PRODUCTS COLLECTION AND REMOVAL FROM THE SURFACE OF GROUND WATERS |
| The known method of oil products collection and removal from the surface of ground waters includes construction of an anti-filtering barrier and a drain installation. In the method being patented, an internal dam from mineral ground is first built over the perimeter of an area being cleaned, and an external dam is then constructed at a distance from the internal dam. Thereafter, an anti-filtering barrier, passing through the internal dam at a depth below the level of the formed oil product lens sole but which doesn’t reach the water confining stratum, and through the external dam at the water confining stratum level, is built. Then, water is delivered to the space formed by the dams, and the ground is saturated with water, thus expelling oil products to the ground surface where a drain installation, lowered below the root level layer and the depth of the foundation of constructions and facilities, operates.

| A METHOD OF AND DEVICE FOR MOTOR FUEL MODIFICATION |
| In a traditional motor fuel modification method provides for injection of an ozone-air in a fuel and their consequent mixture.
In the newly-developed technology, ozone-air mixture is injected and mixed with a fuel in the fuel ejection process. Then, current is supplied to a part of the prepared mixture to produce additional turbulent flows in the mixture during its transition through a mixing chamber. The prepared mixture is delivered to a constant pressure tank and then filtered to remove foam, solid particles and fuel hydroxyl water solutions. After that, the process is repeated at least once more. |
