A protein skimmer, foam fractioner or protein skimmer is a device used in marine aquariums to remove organic compounds from the water before breaking into nitrogenous waste.
Protein skimming is the only form of aquarium filtration that physically removes organic compounds before they begin to decompose, reducing the load on the biological filter and improving the redox potential of the water.
Although the foam division process is known for the removal of waste from aquariums, in fact a rapidly developing chemical process in the large-scale removal of contaminated waste water streams and enrichment of solutions of biomolecules is important.

Protein skimming removes certain organic compounds, including proteins and amino acids, with the polarity of the protein itself. Because of their intrinsic charge, waterborne proteins are either repelled or attracted by the air-to-water interface and these molecules can be described as hydrophobic (e.g., fats and oils) and hydrophilic (such as salt, sugar, ammonia, most amino acids and most inorganic compounds). However, some larger organic molecules have both hydrophobic and hydrophilic portions. These amphipatic molecules are called or amphiphilic. Commercial protein skimming works by generating a large air / water interface, in particular by injecting large numbers of bubbles into the water column. In general, the smaller the bubbles, the more effectively the protein skims because the surface of small bubbles occupy the same volume as larger bubbles of the same size. A large number of small bubbles provides a large air / water interface for hydrophobic organic molecules and amphiphatic organic molecules to collect on the bubble surface (the air / water interface). Water movement speeds up diffusion of organic molecules, which in fact allows bringing more organic molecules to the air / water interface and the organic molecules accumulate on the surface of the air bubbles. This process continues until the interface is saturated, unless the bubble bursts, with the accumulated molecules returning freely into the water column.

All of the foam that has been collected at the top of the protein skimmer water column starts to drain and causes the foam to carry the organic molecules to the skimmate collection cup or a separate skimmate collector.
Organic molecules, and all inorganic molecules that may be bound to the organic molecules, will be drained from the water system.
In addition to the proteins removed by skimming, there are a number of other organic and inorganic molecules that are typically removed. These include a variety of fats, fatty acids, carbohydrates, metals such as copper, and trace elements such as iodine. Particles and other waste is also removed, along with phytoplankton and bacteria. This removal is highly desirable by the aquarist and is often enhanced by the placement of the skimmer for other forms of filtration, so that the load on the filter system as a whole is reduced.
Protein skimmers are used to preserve algae and phytoplankton for cultivation or for commercial sale as living cultures.

Qualities of the Royal Exclusive Bubble King Series

  • Diameter varies from 200 to 650 mm.
  • All pipes are made of GS plexiglass, with a wall thickness of 4 to 6 mm.
  • Load manifold with tapered holes for extra turbulence in the reactor pipe.
  • The foam cup can easily be loosened by hand, and thanks to the inserted 2.5 mm silicone ring, it can easily be sealed without salt crystals forming on the outside.
  • The foam cup only needs 20 mm to be able to remove it.
  • By slightly rotating the outlet pipe, the water level in the foamer can be adjusted very precisely.
  • The foams are supplied with converted Red-Dragon pumps. These are constructed in such a way that no limescale can take place between the rotor and the housing, this by means of an anti-scale bypass.
  • The rotor has been fully adapted, it has received teeth from titanium and with this air and water are mixed in the ideal way.
  • The bearings and the screws are also made of titanium, which makes it very strong.
  • Because everything is made so accurately, it makes little noise at all.
  • The power consumption is between 38 and 78 watts, the amount of water is from 3,000 to 10,000 liters, and the amount of air is between 1,000 and 3,000 liters of air per hour. All this has been measured at a water height of 45 to 65 cm.
  • The standard foams go up to a maximum of 10,000 liters
