FLUID SEPARATOR

The subject of this invention relates to liquid separation equipment according to the invention generally for the separation of the components of a liquid mixture having two components of different density, especially for filtering oil-type contamination from water, e.g.: precipitation water, exceeding many times its own quantity, especially for trapping oil on the surface of trace-line engineering structures mixed with precipitation water and/or oil sticking to solid grains, and preventing by this water-courses receiving precipitation water from becoming contaminated with oil, which liquid separation equipment is built in the way of the precipitation moving towards the receiving water-course, generally in an open-surface channel or ditch and it is paired with a receiving structure installed in the channel or ditch, the receiving structure has a reception side suitable for letting in the contaminated mixture, an intermediate space suitable for separation, and an outlet side suitable for letting out clean water, and the intermediate space does not have a filter or in a different case it has an oleophilic and hydrophobic filter and/or it contains a replaceable filter-box having such filter favourably encased in a framework. The distinctive feature of the invention is that in front of the filter-box, on its part facing the reception side of the equipment, a replaceable frontal delimiting board is inserted, or in a given case the filter-box is encased between the frontal delimiting board and a replaceable additional filter unit situated on the part facing the outlet side of the equipment, the joint unit of the frontal delimiting board, the filter-box and, in a given case, the additional filter unit applied is set in the intermediate space of the reception structure, and in a given case the filter-box is supplemented with a secondary overfall wall on the outlet side of the equipment.
