What is the working process of a floating weir oil skimmer in India?

The working process of a floating weir oil skimmer in India is that the water that is pumping gets an equalized flow created in the skimmer’s mouth. This, skim or the waterfall further takes the loosely floating materials like the weed or the algae into the skimmer. So, this is how an oil skimmer or we should say a floating oil skimmer efficiently works on the removal of duckweed. Other than this these oil skimmers are taken into use at many other places for the removal of oil from the water.
