1.  The Invention



 Oil removal from waters


The problem the inventor(s) wanted to solve

 The aim of the invention is to bind oil pollution on the surface of living waters with a natural material.



 A sponge-like material produced from the stems of sunflowers is used as an absorbing stuff to bound oil pollution. The outside of the stem is removed from the inside sponge-like material and it is grinded to get the absorbing material. This product is put in the elements of a filter cordon, then its blocked or porous form is put into the water.



 The appointed task is solved in a complex way by a decantation procedure and using a cordon consisted of special filter elements. During the procedure we use a natural absorbing material to bind the oil. We put this material in cylindrical closed filter elements which swim in the water. We can compass round all or part of the pollution with forming a cordon from these elements. Moreover, if we disperse the absorbing material onto the surface of the water, it binds the pollution and we can decant the compassed round oil with it. The main point of this procedure is that we use the inside sponge-like part of the stems of sunflowers as natural absorbing stuff. This stuff is put in filter elements and sprinkled onto the surface of the polluted water in a grinded or blocked form. The oil which is bound in the filter elements is taken away from the water together with the absorbing material. To make it, we use such filter elements whose filter cloak can be opened and which can’t rotate. Blocking the absorbing material is necessary because in windy weather the sprinkling can be made more precise and more saving. The wet absorbing material can be pressed into blocks, then it dries and stays in one piece. In the case of still water (lakes), we make a chain from cordon elements and compass the pollution round with it. In the case of living water (rivers), the cordon must be expanded in 45° with the bank facing the swimming of the pollution. The grinded or blocked form of the inside part of the stems of sunflowers is sprinkled onto the compassed separated oil pollution in order to bind the pollution extending on large surface.  At the edge of the pollution the stable non-rotating swimming cordon is able to bind the oil by its fill. So it is guaranteed that no pollution can get out of the cordon. The pollutants bound on the surface can be decanted with a filter. The oil can be destroyed if we burn it together with the cordon, or the oil can be squeezed from the cordon as well.



 Environmental protection



We can make a useful environment-friendly material from a needless one to protect the environment.  The procedure from beginning to end is to protect the environment and moreover, it is not expensive.
