Detailed Description

Protein Skimming, or Foam Fractionation, is a valuable mode of filtration when used with closed recirculating systems

Protein Skimming, or Foam Fractionation, is a valuable mode of filtration when used with closed recirculating systems. Both saltwater and freshwater systems can benefit from protein skimming especially in those carrying intense fish loads.

    How Protein Skimmers / Foam Fractionators Work
  • Protein Skimming is accomplished
    by injecting (with a venturi injector) "Micro-Fine" air bubbles into the water stream as it enters the contact reactor.
  • The "Water-Air" mixture is held inside of the contact reactor for a predetermined retention time (60-120 seconds). During this retention time, the fine air bubbles are given the chance to accumulate dissolved organic wastes and tiny particles on their bubble walls.
  • The many "Micro-Fine" air bubbles,
    laden with organic waste, eventually
    rise to the top of the contact reactor where a dense foam collimates.
  • Once the foam accumulates at the top
    of the reactor, it begins to slowly, but continuously, climb upward through
    the foam collimation tube where it
    works its way out of the reactor and
    into the waste collector. When foam
    exits the reactor, the protein skimming process is complete.
  • Note: Waste effluent will vary from a light colored, yellowish liquid to a dark green. A dark color effluent has less water content, representing a more concentrated waste. Lowering the water level inside the reactor and increasing the foam collimation time will produce a more concentrated waste effluent.
