Pro Tips: Bigger Isn’t Always Better & Smaller Isn’t Always Cheaper

Posted by Tom Hobson on Feb 8, 2017 8:30:00 AM

Choosing a skimmer based on size speculation can be a costly mistake. Buying the smallest skimmer available because it is the cheapest or purchasing the biggest skimmer because you think it will work faster will not lead to successful skimming results.

What Size to Buy?

  • Oil skimmers should be selected by the size of the area that needs to be skimmed, not just by the amount of oil needing to be removed.
  • Choosing an oil skimmer that has the capacity to remove at least 2 times the capacity needed by the application should be the deciding factor.
  • Oil skimmer capacities are based on optimum conditions and homogeneity of oil.
  • Viscosity, temperature of the water, and other factors can affect the amount of oil picked up by an oil skimmer.
  • It is impossible to accurately predict how fast your oil will be picked up.
  • Therefore, as a rule of thumb, purchase an oil skimmer that is rated at least twice the capacity needed.

Make A Plan!

  • Planning is important! Before spending money on a concrete pad and mounting arrangements, check where the oil actually collects in your process.
  • Oil skimmers should be located opposite from the inflow and the tail pulley should be submerged two inches below the surface of the liquid in order to be as effective as possible.
  • Using a tank that does not allow enough time for the oil to rise and float will not permit successful oil skimming.
  • Always make sure your tank gives enough residence time for the oil to float.
