ABSTRACT:
This invention relates to a concentrator for the recovery of a water-immiscible liquid pollutant floating on the surface of a sheet of water, which comprises a duct of flexible material having an inlet orifice with a larger and a small dimension along mutually perpendicular axes for locating with its larger dimension substantially parallel to the surface of the sheet of water, the shape of the duct varying along its length such that at its end remote from the inlet orifice it has a section with a larger and a smaller dimension along mutually perpendicular axes, its larger dimension being in a plane substantially perpendicular to the surface of the sheet of water when the larger dimension of the inlet orifice is parallel to the surface of the sheet of water, and at least one outlet orifice for the outflow of the liquid pollutant from the concentrator, and to systems using such concentrators.
